- Marth Debuted in "Smash Bros.": Vincent's first appearance in CPUCS is not his first appearance in Alpharad's Youtube channel, as he's introduced in "The Real Best Character in Ultimate" prior to the series' debut. Some newcomers had this confusion once exposed to the series before dwelving deeper into Alpha's channel.
- Official Fan-Submitted Content: LinusH111 was a Reddit user who thought the tournaments were real, and asked to be included in one. 3 episodes, and hundreds of memes later, Linus' Mii Fighter made it into a tournament.
- Schedule Slip:
- There was no new episode on March 24th, 2019 due to Alpharad's food poisoning that week. On a lighter note, a small break was taken for April 7th.
- Downplayed for Easter's episode, which was merely delayed for a day.
- Word of God:
- Regarding the Sponsorships, Alpharad clarified they are chosen not just for their high level play or common appearences, but mostly because of their funny implications (Audible | Link doesn't talk, Skillshare | Kirby copies abilities, etc.)
- PG | Incineroar missing out "ENDGAME" was a genuine mistake as the gang forgot he was highly requested.
- The Stinger for "ENDGAME" caused wild speculation until it was recently confirmed the Mii appearing in the foreground was not Vincent's daughter but instead "a Fan".
- "ENDGAME" was announced to have canonical deaths prior to it's airing. As of recently, there are no plans to bring back the fallen.
