Miner

How to unlock: The Miner's drop-pod is found in the Magma Caverns, Stage 4. It has a chance to spawn at the right of the map, at the end of a lava tunnel. After reaching his area, a miniboss Elder Lemurian (called Dire Seeker) will spawn. Defeating the Lemurian will unlock the Miner.

The Miner has short range but many dashes. In order to survive, you will have to balance both dashes and your extra jump to avoid enemy fire. Remember that Crush does a lot of damage!
