9. X-O Manowar

I think the problem with most Valiant characters is that, while they aren't any stranger than other comic book superheroes, they're less familiar than the Marvel or DC crowd, so they seem that way. Like, we all have a frame of reference for Batman, but X-O Manowar?

That's a little stranger.

Aric is a Roman-era Visigoth barbarian who iss abducted and enslaved by aliens. And he gets his hand cut off. So Aric eventually leads a slave rebellion and obtains the alien's greatest weapon, a suit of armor known as the Manowar. Aric puts it on, obliterates the aliens, and flees to earth, only to find that it's been hundreds of years and earth has changed a lot.

So he decides to just approach everything like a barbarian with crazy powers and a suit of laser armor. This is why X-O Manowar is great.  Just so, so great.
