Burner Man (Mega Man) | Buster Only No Damage

This boss' difficulty is overblown. He's pretty reactable too, he'll start out dashing at you and then either jump in the air and crash down towards you, throw those barrels at you, or throw traps and do a wave burner like he did at the end. You can avoid both Wave Burner attacks by sliding under him back and forth, just the one with traps is a constant Burner so it's a bit trickier to avoid, but very much possible. Once you get in a rhythm he's a damn fun fight.
