S'up, Uncle G?
~ Pizza Steve greeting Uncle Grandpa.

Pizza Steve is the tetartagonist in the children's cartoon Uncle Grandpa. However, he does play a few antagonistic roles on the show.


Pizza Steve lets on to everyone that he is full of himself. He often claims to have many achievements and statuses that he doesn't really have. He is very fretful, concerned, and apprehensive about his image because he is highly insecure and has self esteem issues. He does not want anyone to know of these issues, though, because he not only needs everyone to believe he is cool, he also needs to convince himself that he is cool. He often cries or mopes when no one is around. He also becomes very timid, cowardly, pusillanimous, and gutless when situations don't work out the way he wants them to. His insecurities cause him to act out in an unstable and temperamental manner, which can be troublesome and uncooperative when he is expected to be evidently demonstrative and loyal to his friends.


He is a slice of pizza with pepperoni and gooey cheese. He wears sunglasses with a glare and has tiny hands and feet. He also has the ability to stretch his arms and legs to different lengths, as shown throughout the series.

As revealed in the comic Uncle Grandpa No. 1 story, "Uncle Grandpa Needs Glasses", Pizza Steve's human form is a young woman with long and voluminous reddish-brown hair, amber eyes, freckles, red lips, and a thin body structure. It is revealed by Yehudi Mercado that this is actually how Uncle Grandpa sees Pizza Steve.

When the lie detector test came in, it was Pizza Steve, but Uncle Grandpa was reading it and he said he couldn't read so Pizza Steve read it and said it was Mr. Gus.

  • "Bad Morning": One of Pizza Steve's most antagonistic role. Although by accident, he is the reason why Uncle Grandpa is grouchy and argumentative because he was going to get some ice cream, but the RV was off limits, so he drove Uncle Grandpa's racecar bed, but parked it on the wrong side when he got back, to which Mr. Gus made sure that he is banned from driving.
