Rangda Bangda

Rangda Bangda (ランダ・バンダ) is the boss of the second Sigma Palace stage of Mega Man X and its remake Maverick Hunter X. It is based on an ancient wall painting Sigma once saw.

It looks like a face in the background wall with moving eyes, a nose gun, and a mouth serving as a pit of spikes. It can also move its side walls inward to try and force X into the spiked pit. In Mega Man X and its remake, the best weapons to use against it are Chameleon Sting and Rolling Shield.

Mega Man X5
This Rangda Bangda (ランダ・バンダ) is a modification that appears in Mega Man X5 with an Egyptian themed look and a remix of the fortress boss music from the original Mega Man X.

It has three eyes, each with a different color and attack, that appear one at time from one of the two eye cavities. The blue eye will move straight in X's direction, the green eye will shoot, and the red eye will spread several projectiles in two directions. When the walls move in to limit the player's movement, a small, miniature sun-like object will follow the player and spikes will appear on the floor, and sometimes on parts of the wall. It is recommended to use X equipped with the Gaea Armor against it.

Rangda Bangda, along with the boss that precedes directly before it, the Shadow Devil, are considered two of the hardest bosses in the entire Mega Man franchise. 

Trivia

 * In Mega Man Zero 4, a similar (though much smaller) robot, named Randam Bandam, appears in the second final stage.


 * The first part of Rangda Bangda's name is the same as Rangda, a wicked witch of Balinese folklore who represented evil.
 * It is possible to use the Hadouken on Rangda Bangda's core in the original and the remake of Mega Man X, however it requires very quick and perfect timing of the charged Shotgun Ice on the walls, and then using the Hadouken on the core before it makes contact with X.
 * There is a glitch in the iPhone version of Mega Man X when X destroys the nose. When the nose is gone, the walls cannot move, making it difficult for X to see the eyes. The only way to get rid of it is to defeat Rangda Bangda or dying.
