Master Mega

Master Mega is Shiver's shark in Return of the Mammalians.

Appearance
Master Mega is a large shark resembling a great white shark with a saddle, rocket boosters on his back, and a pair of 18k Aviators on his head. Shiver will ride on his back until enough damage is dealt. Master Mega has a spawn point on his forehead for when Shiver is splatted. When Master Mega has taken enough damage, his eyes will change to having an X instead of his regular eyes due to cartoon-style characters typically having X eyes when they die.

Shiver and Master Mega are fought as the third boss of the single-player campaign. Later, after Deep Cut have allied with the New Squidbeak Splatoon, Shiver briefly lends Master Mega to Agent 3 to help them boost into space to stop Mr. Grizz.
