Strangle Bads

Strangle Bads is the son of Jotaro Kujo, and the main villain of season 1.

He created Flaming Super Saiyan.

We don't know anything about his mother except that, because he made Flaming Super Saiyan, she must have been at least part Saiyan. Fans say she was actually Bulla, Bulma's second child! He might have just been adopted by Jotaro though, and might be another of Vegeta and Bulma's child.

He was going to kill Goku but was killed by Buu before he could.

His name is Japaneas for 'Kill of Goku.'

He is alive because the incompetent Super Porunga revived him.
