Since the next DLC character for Nickelodeon All Star Brawl is coming hopefully tomorrow I thought I would do a tier list of what future characters I would like to see as DLC so here it is.
My Most Wanted: Jimmy Neutron Hugh Neutron Timmy Turner XJ9 Squidward.
Would Be Great: Rocko Dib Doug ( Even though he's owned by Disney now ) El Tigre Raphael Donatello Dudley Puppy Kitty Katswell Mr Krabs Plankton Zuko Crimson Chin Arnold.
Don't Really Want But I Wouldn't Mind: Any character from Spliced Any other villain from TMNT besides Shredder Eliza Thornberry Goku ( Yes Dragon Ball Z did air on Nickelodeon at one point ) Otis Tommy Pickles Daggett and Norbert.
Don't Want: Fanboy and Chum Chum Mr Blik Bessie Higgenbottom Any Nick Jr character.
Also regarding about a character from Spliced I did some research and found it the show aired on Teletoon in Canada and on Nicktoons in the UK so in my research Nickelodeon doesn't technically own Spliced but it would surprising it a character from that show does get in.
