If imgflip-bossfights characters had boss themes from other video games (in my opinion); Megalovania (Undertale); The World Revolving (Deltarune); In Dire Need (Hyrule Warriors: Age Of Calamity); Egg Mobile (Sonic Adventure); Fury Bowser Phase 1 (Bowser's Fury); Calamity Ganon (Legend Of Zelda: Breath Of The Wild); The Part Where He Kills You (Portal 2); 1-1 (Super Mario Bros)
