There are 3 comics with Doctor Aveo, and they’re all here on Kenny Chronicles. Meanwhile, there are a lot of comics with Kenny’s brother, and you can see them all here, also on Kenny Chronicles. There’s definitely a resemblance. Neither character has been seen on Ferrets Vs Lemmings yet. Patrick would be 13 now.

The year is 2132

Death: You really splurged on Fuego’s new house. Two floors?! What’s he going to do with two floors?

Kenny:
Run around and yell “Whee!”, probably.

Death: Not even our doctor has that much space.

Kenny: Well, Dr. Aveo kinda has two houses, anyway, since he visits his son so much.

Death: Oh? Who’s his son?
Kenny: What? My brother is his son! That’s how we got him to move here! You didn’t know that?

Death: It’s never been mentioned.
