Charges for 2 s and fires 5 bursts of homing bullets.
How to dodge it: Cover alone is not enough: run at him while dodging; up close they cannot turn in time.

How to dodge it: Get out of the purple puddle at once: it kills in seconds.
He crouches and spins a huge beam that goes through walls, two turns, lower each time.
How to dodge it: Hiding does not work here: jump the beam, or get under or above him.
From phase 2: he rears up, opens his body and creates a 50 m sphere that pulls you in and kills on contact, regardless of extra lives.
How to dodge it: Run the other way as soon as he rears up, or get behind a rock so it stops the pull.
