What would be a clever nickname like this one?

Well, me and my friends are playing some wrestling on a Role-Playing site called Gaia Online in the forums. One guy who’s truly a veteran has a screen-name of [M]a.r.t.s, and his superstar’s name is Marxx, which is really cool since it sounds the same. Can someone give me a name like that for me to use?

the letters cks can be replaced with an x
the letters y and i can replace each other
double oo’s replsces u’s

use that small guide to try and make something up
