Caddicarus

Caddicarus is an English gaming YouTuber who has collaborated with Scott Wozniak on multiple occasions. He is first seen in Episode 100: It's Awesome Baby! where he is shown talking about Dick Vitale's "Awesome Baby" College Hoops, and also makes a brief cameo in Episode 200: Borderline Forever. Scott Wozniak has also appeared in two of Caddicarus's episodes. He is played by Jim Caddick.

In It's Awesome Baby!
When Scott Wozniak firsts arrives in the Awesome Baby Universe he searches up "madden" on Google, which brings up no results, he then searches up "Dick Vitales Awesome Baby College Hoops" which takes up videos of YouTubers covering Dick Vitale's "Awesome Baby" College Hoops, one of them being Caddicarus.

In Borderline Forever
Caddicarus appears in the montage of Youtubers watching Scott's tape on how to talk about video games. He appears to be either confused or offended at the video for unknown reasons.

In PlayStation All Stars Battle Royale ft. Scott The Woz
In the video, Caddicarus covers PlayStation All-Stars Battle Royale along with Scott Wozniak. Caddicarus initially call Scott in order to play Super Smash Bros. Ultimate, but ends up talking about PSASBR instead due to a mysterious swap. A recurring joke in the video is Scott Wozniak only talking about the game because he received alcohol from Caddicarus.

In The Stupid World of Portable Crash Bandicoot Games
Wozniak makes a brief appearance in this episode where Caddicarus is covering all the portable Crash Bandicoot games. Caddicarus calls for Wozniak and asks him to give him the next portable Crash game, threatening to reveal where the blue border is from if he doesn't.

Wozniak initially acts confused at this request and refuses, so to force him to do as he says, Caddicarus zooms out the video and shows Wozniak is filming on Crash's blue pants - thus explaining why a blue border is present in all his videos. Embarrassed at this revelation, Wozniak gives him the next game - which turns out to be Crash Purple: Ripto's Rampage, much to the dismay of Caddicarus and amusement of Wozniak.

Trivia

 * Caddicarus is one of the few people to seem skeptical about Dick Vitale's "Awesome Baby" College Hoops (along with Scott Wozniak, Sam, Joe Robertson, and Dom), however, this might be a joke as it was included in one of his videos (with most of his videos being comedic).
 * This also might be because since Supreme Leader only took over the US government, Caddy, as a UK Youtuber, would not be in a place where Dick Vitale is mandatory.
