Chestbeater enemy line

The Chestbeater and Wild Gorilla are enemies that are randomly battled in Golden Sun: The Lost Age. These monsters, resembling bulky gorillas, are palette swaps of each other that have differing levels of power and defense and are fought in different locations in the game. Three of the Chestbeater enemy serve together as a boss encounter.

Chestbeater
A Chestbeater is a level 9 variant with brown fur and blue skin. This enemy is battled at only one occasion in The Lost Age; at the end of the "first" dungeon, Kandorean Temple, a scripted encounter with three Chestbeaters occurs, which is treated as a boss encounter and the game's first.

Despite the statistics of the Chestbeaters, this first boss encounter in the game can be quite simple for one reason: your party's offensive Psynergy spells. Spells like Earthquake, Ray, and Flare Wall will all deal rather hefty damage to all three monsters at once, so just keep using these spells until the battle is over rather quickly. This battle is easily won through this method even on Hard Mode (provided your party has the PP necessary, as well as being at full health and Herbs at the ready).

The scripted battle with the Chestbeaters is normally required in order to progress through the game, but by means of the Retreat glitch, it is possible to bypass the battle and enter the upper rooms of the temple directly. If this is done, the battle can be initiated at any later time either by approaching them as would normally be done, or by climbing down the ladder from the upper room. With that method, the ladder is invisible before the Chestbeaters are defeated, and the monsters themselves are incorporeal; it is possible to walk right through them. Even when approached from the back, the battle does not start until the player moves to the space in front of them where the battle would normally be triggered. Alternatively, the boss battle can be skipped entirely; if glitches are considered in a playthrough, the battle with the Chestbeaters is completely optional.

A Chestbeater's statistics are as follows:

A Chestbeater uses the following battle commands with :

As a not-unintelligent enemy that carries stocked items, one 12.5% "ability slot" segment of the Chestbeater's 25% chance to use Claw Attack and two 12.5% "ability slots" amounting to a 25% segment of its 50% chance to Attack will instead cause the Chestbeater to use one of its stocked items if it has any items remaining in stock; if it no longer has items in stock, it will use the called ability as normal. Its full inventory of items is as follows:
 * [[File:Herb.gif]] 2 Herbs: An item that restores roughly 50 HP to either the user or its ally.

Wild Gorilla
A Wild Gorilla is a level 16 variant with purple fur and beige skin. It is first fought in Gondowan Cliffs, and is subsequently fought in Kibombo Mountains.

The Wild Gorilla is pretty much equally strong and durable to the Wyvern Chick in where it can be first fought, and not as strong as the Assassin in where it is later fought.

A Wild Gorilla's statistics are as follows:

A Wild Gorilla uses the following battle commands with :

Crazy Gorilla
Like with all other enemy lines introduced in The Lost Age that seem to have only two variants, a third palette-swapped variant to this line exists in the code of the game cart and was even given its own name, but has none of its statistics and abilities coded beyond weak placeholder abilities. Had it been used, it would have appeared as a variant with green fur and purple skin named Crazy Gorilla.
