History UnexpectedCharacter / NickelodeonAllStarBrawl

* Among the paid DLC characters revealed on May 13th 2022, [[WesternAnimation/MyLifeAsATeenageRobot Jenny]] and {{WesternAnimation/Rocko|sModernLife}} were highly-requested additions. But it was assumed that if any character from ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' was added, it would be Jimmy himself, since he's the main character and his inventions give him plenty of interesting possibilities for attacks. Instead, the first ''Jimmy Neutron'' character is his father, Hugh Neutron, a goofy but otherwise normal man, making this the second time, after Nigel Thornberry, that a show's main character is excluded in favor of their father simply because of said father's FountainOfMemes and MemeticBadass reputation. The sequel does bring in Jimmy himself, though Hugh's return has not been officially confirmed.

Let's start with the initial reveal trailer...

** One very unexpected addition is [[WesternAnimation/ElTigreTheAdventuresOfMannyRivera El Tigre]], who is a rather interesting case due to having been allegedly leaked twice... first in an alleged leak from July 4th that was later confirmed fake... posted about a month prior to the game's official reveal... and secondly as part of the aforementioned August 1st leak. This unexpected factor is especially because his series only lasted one season and was largely forgotten by Nickelodeon for several years... with his only official appearances in a Nickelodeon crossover game prior being in the UsefulNotes/NintendoDS version of ''[[VideoGame/NicktoonsUnite Nicktoons: Attack of the Toybots]]'' and in the Franchise/LeapFrog Didj game Nicktoons: Android Invasion, both released over a decade earlier, making his inclusion in ''All-Star Brawl 2'' even more unexpected!

** Not many expected the third Avatar representative to be Azula, because while she is a major antagonist in the series, the most recurring Firebender was series deuteragonist Zuko, who had recently appeared in ''[[VideoGame/NickelodeonKartRacers Nickelodeon Kart Racers 3: Slime Speedway]]'' and was a popular fan-requested character for the first ''Nickelodeon All-Star Brawl''. Thus, a lot of people considered Zuko a more likely choice to represent the Fire Nation instead of his sister. Zuko himself would later be announced as one of the DLC characters for the Season Pass, though it's still odd that his sister was added to the roster before him.
