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.

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.
