Mimiron is a mechanical boss with a slew of abilities for players to deal with. He has two phases: one where he's in his Levianthan MKII tank, and one where he's got a VX-001 Anti-personnel Assault Cannon.
While in his tank Mimiron will toss napalm out dealing AoE damage, fire a plasma blast, drop some mines, and chuck about rockets all while causing a blast wave. With his cannon he will deal fire damage to players within 80 yards of him, do some frontal cone damage, and charge up his lasers for a big ol' blast that puts the BFG to shame.
You can read more about him at WoWWiki.
I should be a fun fight to watch!
