Master Mega

Master Mega is a shark which aids Shiver in Return of the Mammalians.

Appearance
Master Mega is a large shark with a saddle which Shiver sits on, rocket boosters, and a Spawn point for when Shiver gets splatted. He also wears a pair of 18K Aviators on his head. Shiver will ride on his back until enough damage is dealt. When Master Mega has taken enough damage, his regular eyes will have an X shape, similar to how some cartoon characters have "X" eyes when they die.

Return of the Mammalians
In The Pursuit of the Precious, Shiver and Master Mega are the third bosses of the game in the mission, The Pursuit of the Precious. In the first phase, Master Mega uses three simple attacks, for his first attack he will circle the player in a ring of ink around a platform (which Agent 3 stands on.), occasionally sending our vertical slashes, in his second attack, Master Mega will charge at Agent 3 with his mouth open, which can throw a bomb into. For Master Mega's third attack, Master Mega will go underground, creating a ring around him, similar to a Maws, which will sound an alert when Agent 3 is inside the ring, Agent 3 can drop a bomb into the ring, and Master Mega will catch the bomb.

Once Master Mega swallows a bomb, he will fly onto the platform and try to crawl back into his ring of ink, Agent 3 can use Master Mega's vulnerable state to splat him while he's crawling. Once splatted, Shiver will fall off of Master Mega, making her vulnerable as well.

In the second phase, Master Mega will now make ink tornadoes to charge up his main attack, where he fires a beam of ink at Agent 3.

In the third phase, Master Mega will fire three beams of ink at Agent 3 instead of one. Master Mega also crawls faster after swallowing a bomb.

In the Rocket Battle, Master Mega makes another appearance after Shiver lends him to Agent 3 to help them boost into space to stop Mr. Grizz.
