A mysterious masked swordsmen who finds himself in the service of Princess Peach. She and him form a team to take down Bowser and Voldemort. Long story short, it doesn't go well and Meta Knight is the sole survivor. He teams up with Luigi and Edward Elric to hunt down the Koopalings. If they can gather the gems from their wands, the Meta Knight can use it to revive everyone that was reduced to a core.

Personality:
Not much is known about Meta Knight. What we do know is that he's a lethal swordsman of immense caliber and skill. To challenge him in a fight would be suicide. He takes every threat seriously and shows no mercy to whoever his opponent may be. He is also a Grammy winner. Despite all this fame and fear others have for Meta Knight, there is a slight softness akin to that of a father. He cares deeply for his brothers and sisters in arms, even taking time to mourn all the casualties from the raid at Bowser's Keep. There is a hint of survivors guilt plaguing the masked assassin following the failed air raid. 

Voice Direction:
Meta Knight has a mid to low voice that is deep and intimidating. He's a badass with a sword who strikes admiration and fear to anyone he speaks to. Meta Knight has a Castilian Spanish accent. Feel free to come up with your own take based on his personality. (Think a mixture of both his anime voice and his Super Smash Bros Brawl voice, or something like Antonio Bandaress)
