Lizard Man enemy line

The Lizard Man, Lizard Fighter, and Lizard King are species of monsters found in Golden Sun and Golden Sun: The Lost Age. These monsters, resembling bipedal humanoid lizards armed with armor and axes, are palette swaps of each other and have differing levels of power and defense. All are associated with the Mercury element.

Lizard Man
A Lizard Man' is a moderately large member with green skin. The Lizard Man has 129 HP, 106 Attack, 31 Defense, 30 Agility, and 2 Luck. Its resistances are more-or-less balanced; Mercury attacks damage it less while Mars attacks damage it more.

Lizard Men can only attack with either a physical attack or the Monster skill Water Blessing, a strong Mercury spell that strikes up to three Adepts.

Felling a Lizard Man yields 42 EXP, 52 Gold, and in uncommon cases, a Nut. Lizard Men are battled in the Mercury Lighthouse and the area of Angara above Mogall Forest and below Kolima Bridge.

Lizard Fighter
A Lizard Fighter is a large member with blue skin. The Lizard Fighter has 212 HP, 204 Attack, 61 Defense, 60 Agility, and 2 Luck. Its resistances are quite balanced, being only somewhat weak to Mars attacks.

Like their earlier counterparts, Lizard Fighters can only attack with either a physical attack or the Monster skill Water Blessing, a strong Mercury spell that strikes up to three Adepts.

Felling a Lizard Fighter yields 89 EXP, 124 Gold, and in relatively uncommon cases, a Nut. One single Lizard Fighter is battled in Golden Sun, accompanied by two Rabid Bats in a scripted battled on the Tolbi-bound Ship. In The Lost Age on the other hand, Lizard Fighters are fought randomly in the interior of Aqua Rock.

Lizard King
The Lizard King is a large member with orange/brown skin. Only one exists in the game; it is battled as the fifth sub-boss in Crossbone Isle and is therefore far more powerful than its lesser counterparts. It is also accompanied by a Harridan and two Stone Soldiers. The Lizard King has 2000 HP, 54 PP (for launching magic attacks, both which its counterparts do not have), 285 Attack, 93 Defense, 92 Agility, and 13 Luck.

Lizard King has a far stronger arsenal of abilities; It can attack physically, cast Hail Prism and the Monster skills Water Blessing and Ice Blessing as strong multi-Adept Mercury attacks, improve its Attack rating with High Impact, degrade the party’s Attack and Defense ratings with Blunt and Debilitate respectively, and seal an Adept's Psynergy with Bind.

When felled, Lizard King yields 535 EXP which adds up with the three other monsters to make 881 Experience Points total. In addition, it yields 1200 gold and is guaranteed to drop a Psy Crystal.
