Lilu had watched him closely. Her attack at his wrist was a test. Something was blocking ranged spells from hitting him, but her close combat strike with Alpha had injured him and sent him into this mutated insane rage.
Hannibal was an interesting fellow to say the least. He hadn't always been this insane killer. Before his soul upgrade, he was a normal boy. But that fateful day when his soul upgraded it brought with it some conditions. Like Lilu , he would be considered an anomaly. His feat was called "Jekyll and Hyde". His Jekyll side was what Lilu had barged in on. When his soul first upgraded one of the conditions of this feat is that it would activate randomly unless suppressed. The way to suppress it was to consume human flesh.
As a child he fought this and refused to do it. Finally the first random activation happened. He was in his home playing with his parents. When Hyde came forth, it didn't care who this food was before it, he beat and devoured them all.
