Rider is this dude! He's gigantic and loud, he's actually Alexander the Great, and he has a tendency to charge headfirst into danger because pfft, what are you going to do, be CAUTIOUS? Also, he wants to conquer the universe but he's really friendly about it.

I mean if you're going to conquer someplace no reason not to treat the people in it right? C'mon Sora back him up on this one.
