The jitter part I can see happening over and over and it will still be funny.
That is why I recommend the warrior's health be high enough to live through a scream. :x Cyborgs live through it sometimes and it's fine.
That boxing match would be something to see.
Chokes can give human classes a hard time and they need to face you to do damage. :x Warriors are the chokes of humans.
Don't call chokes ugly. It hurt his feelings.. and Jitter's.
Well the warrior class would be just free frags for jitters (ROFL Posessed' comment). Dont call choke ugly, if you do, dont be suprised if a bloodball that destroys your window cracks a piece of glass in your face, and fills your house up with blood. :P Just look at the street and you will see Choke crying and charging bloodballs. Dont take him down if you dont wannt unce jitterskull in your house.

EDIT: I'll post my idea when i get time.
