Liam Leonard is the MC of the story, his original name was Asura, the lord of destruction that led his army to invade the world and almost conquered it if not for his generals betraying him and siding with the hero.
He was a Supervillain and still thinks like one, coming up with several plans to make everyone who wronged him regret getting born. Albeit he hates mindless killing as it causes him more trouble than good. But he's prone to rampage and causes a catastrophe.
Even after transmigrating into a new body, his motto never changed. No one is weak; they are the ones letting themselves be weak. Weakness isn't a sin, remaining weak is a sin. He isn't a hero and won't go out of his way to save anyone unless it benefits him, or they happen to be one of his minions. Trying to save his minions is what led him to fall into the hero's trap, but he doesn't seem to have learned from that, thinking it was his fault for not making sure all of his men were loyal.
In fights, he doesn't care about petty tricks or playing dirty, to him everything goes. He wasn't angry at the hero for making his men betray him and using them to win but was angry at himself for falling for such a trap, and so he wanted to get back at the hero and lead him into a similar pitfall. He'll do anything to win, and won't care about casualty or collateral damage. He's a natural disaster that shouldn't be compared to mankind, albeit weakened; he's still a vicious force of destruction.
He does understand romance, but never had a lover before as everyone was either afraid or reliant on him. Those ones fearful of him, he left, and he killed the ones leeching off him. He absolutely hates those who never try to get stronger or better.
He doesn't hate or like any food in particular, but is fond of meat. He loved it fresh and raw. He was Infamous for devouring his enemies whether they were monsters, demons, or humanoid alike. Asura was a six-armed monstrosity. Based on the deity Asura.
His special ability is [Hakai]. Its skill that deals several types of damage to destroy everything in its wake. At a base level, it sends a wave of slashing, piercing, and bludgeoning damage with one of Liam's attacks.
His answer to the trolley problem is. "I don't care." He would leave the situation as it is, as he believes it's those people's problem and fault for being on the track.
