Acting for Two: The current voice actors*FreezeFlame22, AverageToaster19, Popplio Power, Swoldow EVGRB, Carmen, Mononerd, YoshiEgg95, Cowabunga, BluePastels, GengarOfTheOpera, YuriHaru567, gamesnathanlikes, Quantum, and AzUrArInG are not a huge team, so many characters sound very similar to one another. FreezeFlame22 used to voice all of the characters in the first two seasons and the first three episodes of season 3 of both Carl and Bowser's Koopalings (including the female ones), until he got voice actors to voice some of the characters.
Before hiring voice actors, FreezeFlame22 voiced every single character in both Carl and Bowser's Koopalings, which of course includes the female characters, though these roles have since been assinged to female voice actresses. Freeze continued to play Mary-Lynn even after hiring more voice actors, but this was for only one episode and the role was quickly given to AverageToaster19. The only female character Freeze still voices is Nessa Squidd, Blooper's mother (although that's mainly because all she ever says is "Bloop").
YuriHaru567, who is non-binary, voices some of the female characters.
Cross-Regional Voice Acting: All of the voice actors are located on different parts of the world: AverageToaster19, Popplio Power, Swoldow EVGRB, Carmen, YuriHaru567, gamesnathanlikes, Quantum, BluePastels, GengarOfTheOpera and AzUrArInG are located on different parts of the United States, FreezeFlame22 and Mononerd are located in the United Kingdom, Cowabunga is located in Canada, and YoshiEgg95 is located in Germany.
Descended Creator: FreezeFlame22 not only creates the scripts and the sprites necesary for the videos,notePopplio Power writes the scripts alongside Freeze, while the sprites are made by Freeze, Popplio Power, Cowabunga and Oatzimir but he also voices many of the characters that appear on them.
Fake American: FreezeFlame22 and Mononerd are British, but they put on an American accent for many of their voice roles.
Fake Brit: Carmen is American, but puts on a British accent for some of her roles.
International Coproduction: In a way, Freeze's series are produced across three countries, The United Kingdom, The United States, and Canada, due to the members of his team being mainly located on those countries.
Many characters that used to be voiced by FreezeFlame22 were later assigned to other voice actors after he hired a team of voice actors in 2018.
Dedede was originally voiced by AzUrArInG, for both Carl and Bowser's Koopalings, but after he left the team, his voice actor became Popplio Power.
When InstaButNot left the team in January 2023, many of his roles had to be recast to other voice actors.
During the year 2023, Many of Carmen's and AverageToaster19's roles were recast to other voice actors to lessen the load on them.
Promoted Fanboy: Most of the voice actors in Freeze's series started out as fans of his videos. Popplio Power, Swoldow EVGRB, AverageToaster19, Cowabunga, YuriHaru567 and AzUrArInG in particular have been fans of Freeze ever since he was working on The Koopa Kids way back during the early 2010s.
Role-Ending Misdemeanor: On March 25, 2024, Kelly Nora Queen was abruptly fired from the team after evidence surfaced of her unsavory behavior, including sending inappropriate photos to a minor.
FreezeFlame22 had originally planned for a project to be developed around the time Bowser's Koopalings was still in development. It was titled Mario & Bowser: Behind The Beef. However this was later scrapped, as FreezeFlame22 decided he no longer wanted Mario to be involved in Bowser's backstory, or the show as a whole again, in addition to thinking the title was horrible.
The list of Monarchs of the Koopa Kingdom has changed many times, with many of the kings and queens getting re-named, removed, re-designed, or re-written so that they are not a monarch, but either a claimant to the throne, have a close connection to another monarch, or be completely unrelated to the monarchy.
