Anglerge

Anglerge (アングラーゲ) is the angler Mechaniloid mini-boss, and there are two of them in Launch Octopus's stage in Mega Man X and Mega Man Xtreme 2. It also is found in the first Sigma Palace stage from Mega Man Maverick Hunter X. It has a vacuuming attack (the first can pull the player, and the second push and pull) and sends four snake-like enemies at X, among other things. This enemy has also short appearances in the Rockman X manga.

Trivia
Mega Man X would have three types of Anglerge, but one of them was removed from the game. His data is still in the game though, and can be acessed with a cheat device. It acts like the others, except it push the player with its vacuum attack, suggesting it would be the second Anglerge to appear in Launch Octopus' stage.
