Wyvern enemy line

The Wyvern Chick, Pteranodon, and Winged Lizard are species of monsters found in Golden Sun: The Lost Age. These monsters, resembling flying winged reptiles with bird-like talons, are palette swaps of each other and have differing levels of power and defense. The members of this monster line are notable for their high Agility ratings compared to most other enemies in the areas where they are fought. Despite the similar names, Wyvern Chicks are not in the same monster line as Wyverns.

Wyvern Chick
A Wyvern Chick is a yellow member with a cyan underbody and wings, and a blue head and talons. Wyvern Chick has 124 HP, 128 Attack, 36 Defense, 76 Agility, and 6 Luck. It is most resistant to Venus Psynergy and has decreasing resistance values to Mercury, then Mars, and lastly Jupiter, to which it is extremely susceptible. Wyvern Chick can attack with either a physical attack or the Monster skill Fire Breath, for moderate Mars damage to multiple targets.

Felling a Wyvern Chick yields 83 EXP, 76 Gold, and in uncommon cases, a Weasel's Claw. Wyvern Chicks are battled on Gondowan Cliffs and the World Map area between the cliff and Kibombo. Despite their high Agility rating, they're easy to slay due to their abysmal Jupiter resistance.

Pteranodon
A Pteranodon is a cyan member with a light-green underbody and wings, and a red head and talons. Pteranodon has 242 HP, 291 Attack, 100 Defense, 166 Agility, and 8 Luck. It is most resistant to Venus Psynergy and has decreasing resistance values to Mercury, then Mars, and lastly Jupiter, to which it is extremely susceptible. Pteranodon can attack with a physical attack or the Monster skills Ice Breath, for moderate Mars damage to multiple targets and Banshee Howl, which damages a single party member, possibly inflicting them with Stun.

Felling a Pteranodon yields 341 EXP, 174 Gold, and in uncommon cases, a Nut. Pteranodons are battled on the western side of the World Map as well as Shaman Village Cave and Trial Road.

Winged Lizard
A Winged Lizard is a purple member with a tan underbody and wings, and a light-green head and talons. Winged Lizard has 337 HP, 452 Attack, 160 Defense, 202 Agility, and 6 Luck. It is most resistant to Venus Psynergy and has decreasing resistance values to Mercury, then Mars, and lastly Jupiter, to which it is extremely susceptible.

Winged Lizards are only fought in the optional Yampi Desert Cave dungeon and are one of the weaker enemies in the area.
