Bubble Crab

Bubble Crab, known in Japan as Bubbly Crablos (バブリー・クラブロス), is a crab-based Maverick from Mega Man X2. He was once Maverick Hunter and served in the 6th Naval Unit along with Wheel Gator (the two had a strained working relationship and always argued). Being extremely avaricious, Bubble's only motivation in life was to amass great wealth, joined Sigma's rebellion seeing it as his big break. He was put in charge of transportation, and tasked with defending the Mavericks' deep-sea submarine base.

Strategy
His room has a rising and falling tide, which can sometimes make him difficult to fight if the player is not prepared. He falls easily to the Spin Wheel, however. He also has a fairly easy to manipulate AI pattern: whenever X is above him, he will jump upwards with his claws. If the tide is high enough, it is possible to lock him into this pattern by jumping over him and back, firing as he hits the ground, then repeating the process. If done correctly, Bubble Crab may never use a different attack.

Trivia

 * His level music reappears remastered in Mega Man X5, as Duff McWhalen's stage theme.
 * Strangely, Bubble Crab's crab claws are not located at the end of his arms, but rather in his shoulders that protrude upward in attack. He also has a second pair of eyes attached to stalks, much like a real crab. They do not seem to function as eyes, however, and only flash during certain attacks, suggesting that they serve to store or channel power.
 * When you are there at the giant fish part just right after the beginning of the stage, there will be a platform to be destroyed; slide through the wall on the left side, there will be an empty room there, use a charged Silk Shot and you will gain instant Life Capsule.
