D.Va
D.Va is the winner of most simple character in Overwatch. Hold down left click and never have to reload and fly around a get rid of every projectile in the game. If you get your Ult, you get to blow everybody up and take a selfie and get ten million likes on Twitter.
Orisa
Orisa is a Alt of Reinhardt and can create shields and have a super powerful gun and stop people in their tracks.
Reinhardt
Reinhardt can project a large shield and can hit people with his hammer. He is really just a meat sheild but you can charge in and suicide if you want.
Roadhog
Death in the shape of a hog. Uses a hook to bring your enemies to you. Use a super annoying shotgun to kill everyone.
Winston
Winston is a big gorilla and has a lightning gun. He leaps around and creates dome shields.
Zarya
She creates shields and has a gun that makes a beam of death and destuction. She's a bit too hard for me to play, I have to admit.
