Katt Williams is a wanted man -- now that a Seattle judge has issued a warrant for his arrest.

The train-wreck comic skipped an arraignment this morning at which he was to dig into a combo platter of charges, including assault, harassment and obstruction -- all stemming from his bar fight in Seattle on December 2nd.

That doesn't even touch on the rest of Katt's recent crime spree -- slapping a Target employee, whipping an audience member with a microphone or fleeing cops on a three-wheeled motorcycle.

Katt's mouthpiece says the comic missed the date over "medical issues," but the court didn't buy it and issued a bench warrant.
