RICK GRIMES:
Rick is the complete opposite to the real character.
Whom is typically calm, and a natural leader, but would cut your head off without a moment's hesitation.
Spoof Rick is instead a complete moron who most times doesn't even know what zombies "are".
And most of his "murders" were done out of stupidity.
EXAMPLE: Accidentally shooting Shane further damaging him when he tried "saving him" (kicking him in the wound).
Rick even believes he was a stripper instead of a cop (though he still admits that he became a cop because someone gave the uniform to first person that walk past them).
But Rick is still a export fighter.
And knows how to handle a gun. As he easily kills people and zombies a like..

SHANE WALSH:
Shane is almost the same as he is in the actual series. But he is also shown to be quite immature.
As he responds to most situations by "yelling and pacing".
And when Rick reveals he didn't like Godfather, Shane wanted to kill him that much "more"..
And Shane can become easily angered by.. Well.. Anything really..

GOVERNER:
Governor is almost exactly liked abridged Frieza.
Especially for his tendacies to overuse black humour, and being overly sarcastic..

GLENN:
No info...

MERLE:
Merle is shown to probably the most immature of the characters.
He takes nothing seriously. And just has fun with it all.
Even life threatening situations he remains unserious and overly sarcastic..

CARL:
No info..
