Gilthunder was a seemingly cold and cruel individual around the start of the story, devastating a town by stopping its source of income simply because he was angry with them. When he learned that a child pulled out his sword, he threw a spear at the town just to check whether it or not it was an accident, even though the town could have been destroyed. However, despite that, he is honorable. He has a desire to kill the Seven Deadly Sins for supposedly killing his father. To prove that he has, both, surpassed & to avenge his father, he attempts to hunt and kill the Seven Deadly Sins.

In his childhood, Gilthunder was a sweet and friendly child. However, later in the story, it was revealed that Gilthunder was acting cruel and ruthless. He returns to his old and kinder self later on in the future.
