I think he's quite descent threat for Aladdin and his allies, though he's bit weak when facing Sinbad.

Even his voice is quite good, (I mean come on it's same guy who voiced Guts!!)

Wow, finally someone replied, thanks!

To be honest, I meant what do you think about his history (in Alma Torran) and his behavior when his brother was murdered

But thanks for your answer :D

I haven't read the manga, only seen the anime.

Gonna admit however, I kinda feel sorry for him that he lost someone.

You're welcome.
