I forgot how to beat this boss - Sonic 3 & Knuckles part 11

Final level! Death Egg Zone is home to all sorts of cool mechanics. These include a laser traversal system, gravitation shifts, seesaw platforms and bosses that I don't remember how to beat.

With Hyper Sonic unlocked, we also get access to the bonus Doomday Zone, which sees us chasing an Egg Robo through space to reclaim the Master Emerald.
