This was a cartoon done way back when I worked at a caricature stand. My co-worker ("Polish Mark") was an incredibly talented illustrator who pitched us his cartoon ideas on the slow days. This was one of them.
The Decider is Mark's idea of the most overwrought classic action hero who is now past his prime, able to speak only in bad one-liners, and unable to cope with everyday life. Think Rambo-Bruce Willis-Brock Sampson.
I'm going to throw out there that the voice acting and the final scene are not the best, period. Something about tweens just makes me feel like a bastard.
