Mega Buster

The Mega Buster, known in Japan as Rock Buster, is 's standard special move in Super Smash Flash 2.

Overview
When performed, Mega Man holds his Mega Buster, his arm cannon, in front of him and fires a plasma shot forward. Tapping the special input will fire a small, slow plasma bullet in a straight trajectory forward, dealing minimal damage and little to no knockback. Up to three can be fired at once, and they can be fired while walking and jumping. Holding the special move key will charge energy for a bigger and more powerful shot. There are four stages of charge depending on how long the key is held down for:
 * Level 1 (uncharged) deals 1% damage to the opponent.
 * Level 2 deals 12% damage to the opponent.
 * Level 3 deals 15% damage to the opponent.
 * Level 4 (fully charged) deals 18% damage to the opponent and causes slight recoil on Mega Man.

The player can move around and jump up to once while charging, but they cannot grab the ledge and will lose the charge upon flinching. They will also turn around in the air if the opposite directional input they're facing in is pressed.

Origin
The Mega Buster has been Mega Man's default weapon in nearly every game he appears in, ever since the first game in the Mega Man series. The standard energy bullets, known as "Solar Bullets", are weak but can be rapid-fired with up to three appearing on-screen at a time. It wasn't until Mega Man 4 that Mega Man could charge his Mega Buster for a more powerful "Charge Shot", which could be done by holding the same button used to fire. Mega Man could run, jump, and climb ladders while charging, but in certain games, getting hit while charging will lose the charge. Overall, the Mega Buster functions nearly identically to how it does in SSF2, only in this game shots cannot go through walls and Charge Shots pass through opponents even if they don't defeat them.

Trivia

 * Originally, the Mega Buster allowed only one jump, but after v0.6 of the SSF2 Demo was released, Mega Man could jump twice before being required to return to the ground. However, as of Beta it once again only allows one jump.
 * Earlier versions allowed Mega Man to crouch while charging Mega Buster, but this has been removed as of v0.9a.
 * Prior to Beta, Mega Man's standard special move was instead Weapon Use, and Mega Buster was one of five special weapons that could be changed into Mega Man's standard special move with Weapon Change. However, Weapon Change has since been replaced with Water Wave, thus removing Weapon Use and making this move his only standard special move.
 * In the earlier versions, when copied Mega Man's ability, he could only fire uncharged shots, but now he can charge them up.
