Black Hole Bomb

Black Hole Bomb (ブラックホールボム, Burakku Hōru Bomu) was one of five special weapons that could be changed into 's standard special move with the Weapon Switch in Super Smash Flash 2. As in the Mega Man game it originated from (Mega Man 9), Mega Man shot a controllable large purple projectile that "detonated" into a black hole upon releasing fire. Unlike in the original game, the projectile had a delay before it could be detonated, could only be moved up and down, and continuously moved forward. The projectile moved slowly and sucked characters towards it in a small radius. The black hole that resulted lasted a few seconds, sucked in opponents so they go midair in a large area damaging them for minor damage if they reached its hitbox, and blocked projectiles. The damage that it dealt would not stun opponents and at certain distances the suck in effect only brought opponents airborne. The attack damaged multiple times, with a grand sum of 18% dealt to the opponent if they were hit for the entire duration of the attack.

The pull effect always pulled characters airborne even while the characters were above them and the projectile could be moved behind other characters, projectiles, and reflectors without triggering them. Firing another black hole projectile caused the original black hole to disappear. As of Beta, Weapon Change has been replaced by Water Wave, thus taking this move along with it.

Origin
The Black Hole Bomb is a weapon acquired by defeating Galaxy Man in Mega Man 9. In this game, the player could control where the bomb would go by holding down the shoot button and manipulating the D-pad. The bomb can then suck enemies and projectiles inside, destroying them instantly. It was also Jewel Man's weakness and most effective weapon to use against him. In SSF2 it controls exactly like its Mega Man 9 counterpart, except it doesn't destroys the opponents and does quick but minimal damage.

Trivia

 * Prior to Mega Man's inclusion in SSF2, it was believed that this attack differently. When the attack was used, Mega Man would fire a small purple bomb at the ground. Under normal circumstances, it would fall and explode, but if the button was held, Mega Man's position would be locked and the player could then control the bomb, that would be growing in size as it was controlled. Either way, the bomb would explode and deal damage. The move was also incorrectly named "Controllable Dark Bomb" on Tid's flash2dojo.
 * Originally, Mega Man simply threw the projectile in front of him and the bomb itself obviously only damages enemies instead of KO'ing them outright, but causing considerable damage and flinching the opponent. This has since changed in version 0.7 of the SSF2 Demo.
