Meta Knight is Kirby's rival who boasts unique and speedy swordsmanship. Meta Knight is a great character for beginers because he is very easy to play. His special moves make him very popular and fun. You will probably be seeing a lot of him when you play Brawl.
Meta Knight's special moves:
Neutral Special: Mach Tornado
Meta Knight creates a tornado around him that sucks up opponents.

You can move left or right while using this move, or you can tap the special move button to rise in the air.
Side Special: Drill Rush
Meta Knight will spin like a drill and rush into foes.

You can control this move to make Meta Knight move up or down.

Up Special: Shuttle Loop
Meta Knight's recovery move sends Meta Knight up into the air...

... and sends him gliding horizontally.

Down Special: Dimensional Cape
This move makes Meta Knight disappear to avoid a move.

He will then reappear in another spot.

You can control where Meta Knight reappears by tapping a direction after he disappears. A great way to take advantage of this move is by attacking right after he reappears.
Any idiot can face a crisis - it's day to day living that wears you out.
Anton Chekhov
