Chaos Chimera

The Chaos Chimera is the final boss of Golden Sun: Dark Dawn and is fought below the control station of the Apollo Lens, within Apollo Sanctum.

Story
After the Apollo Lens were activated by Matthew and his friends, their way to the control station is blocked by the Chaos Hound. The Hound nearly attacks the party but it restrains itself when seeing Sveta by their side. It continues some inner struggle until Chalis and Blados (which were supposed to be distracted by Arcanus) reappear and corrupt the hound again, forcing it to fight the party alongside the two Dark Adepts. Their assault fails again, being it the both Adepts or the Chaos Hound defeated and they come up with one last alternative. In an attempt to finally win over the heroes by corrupting the Hound even further with their full Dark Psynergy, the used power sucks them into the beast and results fusing them into a deformed monstrosity.

As a Boss
Chaos Chimera has a lot of HP, moderate attack power, medium Mars and Mercury, high Venus and low Jupiter resistance and acts three times per turn. Its arsenal is a complete monster skill set, featuring several devastating abilities:


 * Attack: A single standard attack.
 * Vicious Embrace: Strikes multiple targets at once with attack power multiplied by 1.6.
 * Retribution: A wide sword strife hits the entire party and may inflict instant KO.
 * Shadow Clash: Causes a hail of darkness which inflicts massive damage.
 * Darksol Gasp: Unleashes a swarm of dark spirits to cause damage and Haunt status.
 * Shriek: Screams at a target, causing minor damage and aborts the target's actions.
 * Chaos Upheaval: A Summon-style monster skill. The Chimera rises high, charging up for an assault from above and comes down with catastrophic force, causing a storm of darkness and destruction.

It may also use the Items of Chalis and Blados:


 * Firecracker: An Item move that causes moderate Mars element damage to several targets.
 * Psy Grenade: An Item move that damages the PP with a range of five.
