Metroid Prime Hunters/Spire

His affinity weapon is the magmaul and his alt-form is the dialanche. Spire is at home in lava arenas. He can stand in lava and not be damaged, as opposed to other Hunters who constantly get burn as they stand in the stuff. The magmaul throws like a grenade and if it hits an enemy, it sets him/her on fire, draining his/her energy. The magmaul does backfire often, especially if you are running and shooting at the same time. The dialanche is a big rock form, not too complex to control, that actually attacks enemies directly as opposed to using bombs. This is useful if you and your enemy are too close for comfort. Spire is the biggest hunter in the game, which may be a weak point.
