5. Friday Night Funkin: If ya dunno what Friday Night Funkin its this very Popular Newgrounds Game you play as "The Boyfriend" That's literally his Name "The Boyfriend" and you basically play through Levels and Face People, Like Pico from Pico's School, it would honestly be so cool to see Brawlhalla and Friday Night Funkin Collab, I predict the Characters for it will be The Boyfriend, The Girlfriend, Daddy Dearest, Skid and Pump and Pico
4. BFDI: Ok I doubt this will happen but it would still be awesome, BFDI Is basically The 1st Object Show ever Created on Youtube, It was Created by Michael and Cary Huang and The Series is extremely Popular, for Characters I predict will be chose I say that Firey, Spongy, Blocky, Four, Woody, Leafy, Yellow Face, Lollipop, Marker, Two and X Would be Valid Choices.
3. The Rabbids: Ok I know this may be Controversial but hear me out, Blue Mammoth has the rights to use Ubisoft Characters so Even though how hated The Rabbids are it would still be funny and Cool to see them in Brawlhalla.
2. Undertale: I dont think I really have to explain this one since Most People here probably already know what it is, I predict only 3 Characters from Undertale will get in and I believe they will be Frisk, Sans (Obviously) and Flowey, because why not, Just like Flowey said "Its Kill, or Be Killed".
Five Nights at Freddy's: Ok I think this one has a Big Chance, Seeing as Scott Cawthon is such a Nice Guy I think he'd be happy enough to bring his Squad of Animatronics to Brawlhalla, Characters I predict Will get a Shot are Freddy, Bonnie, Chica, Foxy, Springtrap, Nightmare and Golden Freddy.
