"Vega
Who the hell is he? Where is he?
Our determination to both become martial arts fighters is the same,
but his methods are mistaken. He cloaks himself in an aura of evil, and
attacks with fists full of hatred. He claims to be the strongest,
and waits to be called king of the fighters."

Pretty close along those lines
The last line (格闘王の名をほしいままにしている) actually means he wants the title of Fighter King, but I thought that sounded slightly awkward in the surrounding context..so use whichever sounds better to you!
