Gilthunder was a decent character on the show. The talented son of a fallen Grandmaster, he’s more than what he seems.
Like his late father, he’s got some pretty neat light magic.
We at first believe that he’s on the wrong side, probably because he was tricked into thinking The Seven Deadly Sins killed his father.
But all of his actions were to protect Princess Margaret. Always keeping up the act and speaking to Meliodas through old code words.
Once the real demons come, his strength is pretty minor. But the storyline where the witch Vivian kidnapped him out of love remained. He’s eventually freed thanks to Ludociel. I was glad, girl was psycho.
He eventually gets to have a life with Princess Margaret. Both of them reject the throne of Liones. They were among the better couples on the show.
