Mewtwo

How Mewtwo joined the Tourney
Mewtwo received orders from Russian Military Command to capture the organism known as the 'Devil' In pursuit of his mission, he successfully infiltrated The King of Iron Fist Tournament 5, but was unable to locate the organism. Russia was in complete disorder with rampant civil disturbances, all believed to be caused by the covert actions of Mishima Zaibatsu operatives. Commissioned to suppress national unrest, Mewtwo spent quite some time fighting across the country. Without any hesitation to stop the Mishima Zaibatsu of intruding the Russian government, the leaders decided to overthrow their leader, Harley Quinn, and decided to put a bounty on his head before anything may go worst.He was eventually called back by the Russian military and ordered to infiltrate the Smash Bros. Tourney to crush the Mishima Zaibatsu. Mewtwo embarked once again for Japan.

Shadow Ball (Neutral)
The move itself consists of Mewtwo concentrating shadow energy into a round ball to toss at opponents. It is its strongest attack. In order to use it, press the B to charge the attack, and B again to release the attack. The player can save the charge by pushing the shield button or left or right on the control stick. When a full charge is saved, Mewtwo's left hand will constantly glow with dark power. Mewtwo can even charge this in the air, and even when it's fully charged, Mewtwo will still continue to 'charge' it until the player releases it or moves. The charge does electric damage and traps an opponent upon contact. Once fired, the ball will travel in a wave-shaped path, which makes it hard to aim but equally difficult to avoid. A fully charged Shadow Ball does 25% damage, deals great knockback, and explodes on contact with a surface.

Confusion (Side)
Mewtwo psychokinetically whirls the opponent in front of it around and lets the opponent land clumsily on the ground, doing some minor damage in the process.

Teleport (Up)
Mewtwo quickly vanishes and reappears in a different location, depending on how the user tilts the control stick. If it teleports into the air, it will fall in a helpless animation. When used quick enough on the ground, it can be used in place of a dodge, side step, or rolling, as there is less lag time and it throws the opponent off. The only way to travel faster with Mewtwo is its wavedash. This third jump, along with its other normal two jumps, allows for Mewtwo's superbly long and safe recovery. Teleport also passes through attacks. However, this attack does not cause any damage to the opponent.

Disable (Down)
Mewtwo shoots out a short beam from its eyes in front of it, and any opponent right in front of Mewtwo that is facing it will be dazed for a short period. If the move is performed whilst the character is already dazed, he or she will fly off taking 1% damage, but will recover when they land. The disable will also send foes flying anytime they are in either a dazed state from say a shield break or in an aerial tumble.

Shadow Cannon (Hyper Smash)
A cannon appears, and Mewtwo fires a large beam of shadow out of the cannon, and it deals a high amount of damage. The beam of energy also passes through characters and portions of stages.

Shadow Storm (Final Smash)
Mewtwo flies to the top of the screen in the center of the stage and then shoots a powerful beam attack. Any character in the way of the beam takes minor damage if they are farther away, but a lot more when up close. It also spikes with a set but high knockback when used up close. Mewtwo then holds its hands above its head as it readies the attack, before launching a large beam of Aura downwards. The attack hits multiple times before a big finisher that has significant KO power. Mewtwo can angle the beam sideways during both the windup and the launch, which is a decent way to catch unhit enemies, although angling can also free trapped targets (which otherwise cannot escape). The move is one of the more difficult Final Smashes to use effectively, as flying or floating characters; or characters with a great recovery as may be able to easily outrun the beam, while other characters can manage to dodge most of the attack depending on the stage.
