Achilles likes things like NBA Youngboy or just rappers that say they kill people. He likes seeing people get hurt, he also likes people like him and a friend of his that can talk him into helping out as competition, basically he can sometimes be easily tricked into doing good things. He's soft on Trepid because he knows what she's been through and understands her way of thinking.

Achilles doesn't like Beorn because he thinks he's too stupid to know anything, and he's too friendly with people. He dislikes Agni as well because he's his friend, and that he's also sometimes clueless as well.

Achilles had a friend from elementary that bullied him but he didn't care as long as he was his friend, soon that friend did something so cruel to him that Achilles couldn't take it anymore. In that moment he unlocked something deep within him that would change him forever if it doesn't die out. Achilles opened his eyes gasping for breathe after he locked what he truly is, looking back he looks at the students that are lying on the floor, hurt from what Achilles had done. The friend was yelling at him, "Monster! He's a monster!" Achilles lives with that moment stuck in his head. He's always negative and mean because he doesn't want to hurt somebody he cared about.

His abilities are electrification and flight, he can control lightning with his fingertips or his hands and feet. He can send a thunderbolt towards your home from 10 miles away and he can charge himself up so he can be more powerful, as if he was a thing that could absorb lightning and shoot lightning but he doesn't have to absorb lightning to do this. When thunder charges his body, everything gets enhanced as if he becomes a super superhuman.
