Trinity

There are always cool Matrix costumes out there.

Agent Smith

I think this costume works because this guy already looks like Agent Smith. Sometimes you need to already have the look to make the costume work. He did a great "Mr. Anderson."

Matrix Costume

I think that Trinity had a big thing to do with how popular the Matrix is.

Morpheus

I know this is a goofy poses, but he did look more like Morpheus in this pose
