Tornado Lizard enemy line

The Tornado Lizard, Storm Lizard, and Tempest Lizard are species of monsters battled in Golden Sun. These monsters, resembling very large, powerfully built bipedal lizards, are palette-swapped variants of each other that have differing levels of power and defense and are fought in different locations in the games. This monster line has several noteworthy aspects: All three variants are fought individually in scripted encounters, two of those are actual Boss encounters, and one of those bosses is the only boss in either game that can be fought repeatedly for fun and profit.

Plot significance
This monster line has a slight bearing on the plot of Golden Sun. As resident monsters in the Suhalla Desert, these whirlwind-making beasts made the desert blustery to begin with, but were formerly not so violent, which made passage through the desert turbulent but doable. They are viewed by the people of the town of Suhalla as the spirits of the desert which have become angered by the colonization of the northern part of Gondowan by the Angaran city of Tolbi. The eruption of Mt. Aleph rains Psynergy Stones down across the world, driving many beasts in general mad and violent, including these monsters, making the desert impassable to normal folk.

Babi, the lord of Tolbi, had previously held the Laliveran girl Sheba captive in his palace, but eventually he orders his soldiers escort her back to her hometown, which requires a trip across the desert. Most of the soldiers escorting Sheba across the desert perish from attacks by ravenous Tornado Lizards cloaked in their powerful whirlwinds, while Sheba herself becomes lost in the desert, but the few soldiers that survive watch as Saturos' group then crosses through the desert, then appear to use water to make the lizards drop their whirlwinds before slaying the beasts. (This would mean that the Mercury Adept Alex uses water-based Psynergy on a Tornado Lizard to make it reveal itself, then Saturos and Menardi slay it with their own powerful abilities.) The surviving soldiers then gather buckets of water from Suhalla and douse it on a Tornado Lizard's whirlwind in an attempt to get back to Sheba, but are no match for the monster's combat abilities, and end up in Suhalla badly wounded and in bed.

Isaac's party, having been in pursuit of Saturos' group for a long time, stop in Suhalla and hear the wounded soldiers' accounts of their experiences in the desert and what might have happened to Sheba in there. That clues them in as to how, when they try to cross the desert and get caught up in a whirlwind, they are to cast the Douse Psynergy to allow themselves to properly battle the monster within. The foursome of Adepts defeat each Lizard they come across, and make it through the desert. They find later that Sheba was captured by Saturos' group in the desert.

Tornado Lizard
A Tornado Lizard is a comparatively small, orange variant with a green underbelly and light blue eyes. Statistically, this monster has 530 HP, 37 PP, 267 Attack, 74 Defense, 104 Agility, and 18 Luck, and it acts twice per turn. In terms of resistance, it has a Jupiter Resistance rating of 152, Mercury and Mars Resistance ratings of 100 each, and a Venus Resistance rating of 48, and in regards to its abilities it uses its available Jupiter-based attacks with a Jupiter power rating of 110.

The Tornado Lizard uses these battle commands:
 * Wing Flutter: Used 53 out of 256 times, this is a Monster Skill that shoots out small sets of sharp glowing yellow plumage through multiple Adepts, dealing a Jupiter-based attack with a power rating of 70 and a range of 3 (the Adepts at either side of the specifically targeted Adept will only take 50% of the attack's force, instead of the normal 80%, however).
 * Attack: Used 52 out of 256 times, this is this monster's standard physical attack.
 * Wind Slash: Used 47 out of 256 times, this is a Psynergy spell that projects wide glowing swaths of energy through the party of Adepts, dealing a Jupiter-based attack with a power rating of 50 and a range of 3. This costs 9 of its user's PP.
 * Storm Ray: Used 35 out of 256 times, this is a Psynergy spell that strikes the party of Adepts with lightning, dealing a Jupiter-based attack with a power rating of 65 and a range of 3. This ability consumes 10 of its user's PP.
 * Impact: Used 29 out of 256 times, this is a Psynergy spell that buffs up 1 target on the user's side of the field by increasing the target's current Attack rating by 25%. This ability consumes 7 of its user's PP.
 * Tornado: Used 23 out of 256 times, this is a Psynergy spell that causes two large, electrically charged tornadoes to cycle through the positions of the party of Adepts, dealing a Jupiter-based attack with a power rating of 80 and a range of 5. This consumes 14 of its user's PP.
 * Ward: Used 17 out of 256 times, this is a Psynergy spell that buffs up 1 target on the user's side of the field by increasing each of the target's Elemental Resistances by 40. This ability consumes 3 of its user's PP.

Felling a Tornado Lizard yields 620 Experience Points and 477 Coins, and there is a 1/8 chance that it will drop a Weasel's Claw. If it is felled with the effect of an offensive Venus Djinni, its rewards increase to 806 EXP and 620 Coins, and the chance it will drop its item becomes 1/2. In Golden Sun it is battled throughout Suhalla Desert, but not as a random monster. As hinted in cutscenes both in the desert and in the nearby town of Suhalla, the various whirlwinds that pop up to block off vital paths throughout the desert are caused by these monsters. Stepping into a whirlwind will lift you up into the air, and after a moment you will be flown out of the desert and plopped back onto the overworld in front of the entrance to the desert, forcing you to go through the desert all over again. To pass beyond each whirlwind, you have to defeat the monster, and to initiate a battle with a Tornado Lizard, let yourself get caught up in a whirlwind, open your Psynergy menu, and cast the Douse Psynergy. Once defeated, the Tornado Lizard and its accompanying whirlwind will remain gone from that screen of the desert until you exit Suhalla Desert and reenter it, in which case all defeated Tornado Lizards will respawn.

Obviously the Tornado Lizard's stats and ability to act multiple times in a turn, almost like a boss, are adjusted to provide multiple enemies' worth of challenge in a battle. Its rather powerful abilities and the fact it likely can't be defeated in one turn like many random monsters even though you're focusing all four Adepts on it means it can do a rather hefty amount of damage before going down.

Storm Lizard
The Storm Lizard is a huge, light-green variant with a violet underbelly and violet eyes. Statistically, this is a Boss monster, having 2900 HP, 42 PP, 291 Attack, 86 Defense, 112 Agility, and 22 Luck, and it acts twice per turn. In terms of resistance, it has a Jupiter Resistance rating of 152, Mercury and Mars Resistance ratings of 100 each, and a Venus Resistance rating of 48, and in regards to its abilities it uses its available Jupiter-based attacks with a Jupiter power rating of 110.

The Storm Lizard uses these battle commands:
 * Wing Stroke: Used 53 out of 256 times, this is a Monster Skill that shoots out wide sets of massive glowing yellow feathers through multiple Adepts, dealing a Jupiter-based attack with a power rating of 140 and a range of 3 (the Adepts at either side of the specifically targeted Adept will only take 50% of the attack's force, instead of the normal 80%, however).
 * Attack: Used 52 out of 256 times, this is this monster's standard physical attack.
 * Sonic Slash: Used 47 out of 256 times, this is a Psynergy spell that projects huge glowing swaths of energy through the party of Adepts, dealing a Jupiter-based attack with a power rating of 120 and a range of 5. This costs 20 of its user's PP.
 * Storm Ray: Used 35 out of 256 times, this is a Psynergy spell that strikes the party of Adepts with lightning, dealing a Jupiter-based attack with a power rating of 65 and a range of 3. This ability consumes 10 of its user's PP.
 * Impact: Used 29 out of 256 times, this is a Psynergy spell that buffs up 1 target on the user's side of the field by increasing the target's current Attack rating by 25%. This ability consumes 7 of its user's PP.
 * Tempest: Used 23 out of 256 times, this is a Psynergy spell that causes four large, electrically charged tornadoes to cycle through the positions of the party of Adepts, dealing a Jupiter-based attack with a power rating of 160 and a range of 5. This consumes 27 of its user's PP.
 * Ward: Used 17 out of 256 times, this is a Psynergy spell that buffs up 1 target on the user's side of the field by increasing each of the target's Elemental Resistances by 40. This ability consumes 3 of its user's PP.

Felling the Storm Lizard yields 1300 Experience Points and 6100 Coins, and it is guaranteed to drop a Psy Crystal. If you manage to fell it with the effect of an offensive Venus Djinni, its rewards increase to 1690 EXP and 7930 Coins. In Golden Sun, near the end of Suhalla Desert, you'll find a much larger whirlwind that pursues you until you either get caught up in it like a normal whirlwind or exit the desert (this technically makes this boss fight skippable with fast enough running, but the tornado will remain in its starting location in the desert for if you go back to it, so you can come back for the boss battle later). It operates just like a Tornado Lizard's whirlwind - it will transport you to the beginning of the desert unless you cast Douse while caught up in it, beginning the battle with the boss.

Particularly to a party that has missed a good number of the game's Djinn up to this point (ideally there should be 6 Djinn for each party member at this point), this can be a legitimately difficult boss battle, as the monster is essentially an enhanced Tornado Lizard with several abilities made twice as strong and with a huge amount of HP. The fact its small PP meter allows limited usage of its Psynergy spells hardly detracts from its challenge, because it alternates between its attack and its powerful, multi-target, PP-free monster skill Wing Stroke, and since it acts twice per turn it's entirely possible for it to use Wing Stroke twice per turn. This emphasis on power and repetition makes even a full Summon rushing tactic - where all Adepts use their most powerful summons on the first turn and try to fell the boss afterwards while in a weakened state - very risky and possibly unsuccessful, as the Storm Lizard would very likely down the whole party before it is defeated, at least if each Adept does not have two extra Djinn Set onto them to increase their classes. Helpful measures would include having Mia use Wish Well, getting the Mars Djinni Flash nearby and using it for important group protection (and possibly using Granite for the same purpose), and having Adepts in general use a Set Djinni on one turn and use a 1-Djinni Summon on the next for a more flexible blend of offensive and defense.

Tempest Lizard
The Tempest Lizard is a huge, dark-purple variant with a red underbelly and light green eyes. Statistically, this is a Boss monster just like the Storm Lizard, quite literally: It has almost the same stats, but slightly higher, having 3000 HP, 45 PP, 295 Attack, 94 Defense, 114 Agility, and 26 Luck, and it acts twice per turn. In terms of resistance, it has a Jupiter Resistance rating of 152, Mercury and Mars Resistance ratings of 100 each, and a Venus Resistance rating of 48, and in regards to its abilities it uses its available Jupiter-based attacks with a Jupiter power rating of 110.

The Tempest Lizard is also completely identical to the Storm Lizard in terms of its available battle commands:
 * Wing Stroke: Used 53 out of 256 times, this is a Monster Skill that shoots out wide sets of massive glowing yellow feathers through multiple Adepts, dealing a Jupiter-based attack with a power rating of 140 and a range of 3 (the Adepts at either side of the specifically targeted Adept will only take 50% of the attack's force, instead of the normal 80%, however).
 * Attack: Used 52 out of 256 times, this is this monster's standard physical attack.
 * Sonic Slash: Used 47 out of 256 times, this is a Psynergy spell that projects huge glowing swaths of energy through the party of Adepts, dealing a Jupiter-based attack with a power rating of 120 and a range of 5. This costs 20 of its user's PP.
 * Storm Ray: Used 35 out of 256 times, this is a Psynergy spell that strikes the party of Adepts with lightning, dealing a Jupiter-based attack with a power rating of 65 and a range of 3. This ability consumes 10 of its user's PP.
 * Impact: Used 29 out of 256 times, this is a Psynergy spell that buffs up 1 target on the user's side of the field by increasing the target's current Attack rating by 25%. This ability consumes 7 of its user's PP.
 * Tempest: Used 23 out of 256 times, this is a Psynergy spell that causes four large, electrically charged tornadoes to cycle through the positions of the party of Adepts, dealing a Jupiter-based attack with a power rating of 160 and a range of 5. This consumes 27 of its user's PP.
 * Ward: Used 17 out of 256 times, this is a Psynergy spell that buffs up 1 target on the user's side of the field by increasing each of the target's Elemental Resistances by 40. This ability consumes 3 of its user's PP.

Felling the Tempest Lizard yields 1360 Experience Points and 6400 Coins, and it is guaranteed to drop a Potion. If you manage to fell it with the effect of an offensive Venus Djinni, its rewards increase to 1768 EXP and 8320 Coins. In Golden Sun in Suhalla Desert, you'll see a large pink whirlwind visible at the right of the second screen, which is near a cave exit. To reach this somewhat hidden portion of the screen, use Reveal to get yourself to where you find the Mars Djinni Flash, enter the nearby cave, and follow it until you get to the pink whirlwind. It operates similar to a Tornado Lizard's whirlwind - unless you cast Douse while you're up in midair, which will initiate a boss battle, you will be transported out of the desert.

However, this boss has several very notable characteristics to it in field terms. If you defeat the boss in the desert, its pink whirlwind disappears - but if you leave the desert and reenter it, the boss and its whirlwind reappears the same way normal Tornado Lizards reappear in the desert, making it the only repeatedly fightable boss in the Golden Sun series. What's even more interesting is what happens if you let it carry you off-screen: You are dumped onto the overworld map not around Suhalla, but at the secret dungeon Crossbone Isle, with the Tempest Lizard's tornado nearby at the beach portion. This is the "main" way of accessing Crossbone Isle. Here, you may either enter Crossbone Isle by walking into its center portion and explore, or get caught up in the whirlwind and either use Douse to fight the Tempest Lizard here or ride it back to Suhalla. Like in Suhalla Desert, if you defeat the boss here, its whirlwind disappears from the overworld portion of Crossbone Isle, but immediately respawns upon entering and exiting the nearby Crossbone Isle location, and you can fight it and slay it as many times as you like this way.

Since the repeatedly fightable Tempest Lizard is located so close to the location on Crossbone Isle that causes it to reappear after it is defeated, this makes for a very good way to level-grind for EXP, coins, and Potions. If you have all Djinn and are at a high enough level, it becomes easy to repeatedly slay the monster by having everyone use 4-Djinn summons on the first turn to reduce it to near-zero health, then have Isaac down it with a usage of an offensive Venus Djinni like Flint or Bane, so that you get the enhanced EXP and Coin rewards for your kill. Then heal and walk around the overworld until your Djinn have recovered, put as many Djinn On Standby as needed, battle the Tempest Lizard again with your four summons and one Venus Djinni attack, reap your rewards, and repeat. You can be at a very statistically high level with a lot of free Potions to play around with using this method.

As an actual boss monster, since this boss is a slightly enhanced version of the already powerful and durable Storm Lizard, if you battle it as soon as you are able to (and you can battle it even before the Storm Lizard when you first explore Suhalla Desert), you'll likely have a very difficult time. It is the toughest boss monster outside the game's final boss encounters and the optional battle with Deadbeard at the bottom of Crossbone Isle, but pretty much the same strategies and battling conduct used for the Storm Lizard apply here. Since it can be fought anytime, many players wait until after having been powered up by endgame content (getting more Djinn, equipment like Dragon Scales and Gaia Blade from Venus Lighthouse, etc) before coming back to Suhalla Desert for the Tempest Lizard to either fight it or let it take them to Crossbone Isle.
