Matt Castle destroyed the periodic table, because he only recognizes the element of surprise.
BAM! New character. Carla here with the dangerous Matthew Castle, the terrible spawn of Elektra and the Punisher. Persons of interest are here so he whipped himself up a resume and is now helping the school out with their covert operations techniques. WHO WANTS TO BE A NINJA?
Otherwise... yeah. I think there are maybe one or two people who might have ever heard of the guy, but that's a good thing. He takes after his parents folks, so remember to be good, kids. Because Matt Castle keeps his friends close and his enemies closer.
Close enough to drop them with one round house kick to the face.
