Lizardfolk Heavy: What class should it be?

I am making a Lizardfolk character that is going to have a similar personailty to TF2 Heavy. What class should I have him be (Prob a barbarian, but he won't be into melee attacks)

A character with an unhealthy obsession with an overly powerful and incredibly expensive gun? Artificer artillerist, I would say!

Ok, but I think that fits the Engineer better.

I think artificer suits them both. If the heavy swung axes he'd be a barbarian, but he uses a huge gun, and there's one class that does that!

ok, thanks!
