Superman/Shazam, basically

It'd be really cool to have a superman-like champion, maybe a guy who flies around Metropolis Piltover protecting the city from assassins like Camille or any particularly nasty Zaunites who might want to wreak havoc.

Just a basic concept, 'cause I feel like the champion creators could really flesh out such a character. Of course, instead of an alien he'd probably be magic, more like Captain Marvel Shazam than Superman.
