Charge Beam

The Charge Beam is, according to Samus's Super Smash Bros. Melee trophy, her most powerful weapon. It is in all Metroid games up to date. Usually the Charge Beam has the same power as a missile, though not always the case. It should also be noted even though mostly the Charge Beam has the same strength as a missile, it might not be able to break crumbling rock, etc. that the missile would be able to break. In most side-scrolling games the Charge Beam must be acquired, but in 3-D games it seems to be a weapon available from the start. In 'Super Smash Bros. Melee, if an opponent has high damage, a Chage Beam can easily blast him/her/it offscreen.
