History SNKBoss / OtherFightingGames

* The eponymous Eternal Champion from the [[UsefulNotes/SegaGenesis Genesis]] fighter game ''VideoGame/EternalChampions''. Not only is he as strong as him being on this list would imply, you have to beat him five times in one round, and each time he uses a different (but equally painful) move set.

** Making it through Arcade Mode on Normal or higher will make you fight Boss Sylvan Blackjack. While he spends the first round not using some of his moves (and suffering from occasional bouts of ArtificialStupidity), during the second round he'll permanently enter [[SuperMode Full House Mode]], turning him into a MasterOfAll and giving him infinite use of his devastating Deck Slicer move, which normally drains the Full House gauge with each use. In addition, this also makes it so his "All In" super is always at full power, taking half your health off if it hits you.

** As of Version 0.3.0, going through Arcade Mode on Hard with a GuestFighter from ''VideoGame/{{Schwarzerblitz}}''[[note]]either Mystery Johnson or as someone else in a ''Schwarzerblitz''-themed costume[[/note]], you'll fight that game's arcade boss Donner Misterkay instead of Sylvan. While he's thankfully nowhere near as tough as he is in his home game, he still excels at both rushdown and zoning, and he can spend his whole meter on a OneHitKill move.

*** First off is Machina X Flayon, who fights in a scaled-down version of his R-TRUS mech. Even when scaled down, said mech is still twice as large as the rest of the cast, giving his attacks a bigger reach. He's also ImmuneToFlinching[[note]]makes sense, given that he's in a mecha[[/note]], letting him tank your attacks while he either starts pelting you with missiles or smack you with his missile launcher. He can also call in explosive drones to support him as well as a super where he tackles you up into the air before slamming down on you to deal considerable damage, and can follow up it with a beam explosion to really put the hurt on you. That said, he can be staggered out of his armour state if hit enough times, giving you a chance to combo him.

*** Lastly is Ouro Kronii, who more than lives up to her title of Warden of Time. Like with Flayon, she too is ImmuneToFlinching, letting her tank your attacks while she does her own (although she too can be staggered out of them if hit enough times, though good luck with that when she's straight up blocking your attacks most of the time). Many of her attacks consist of projectile spam, such as firing clock hands at you or tossing out TNT packs that explode after a while, as well as a trap that slows you down like with Amelia's Off-Collab. Her normals also have a longer reach thanks to her clock hands, as does her attack where she spins a clock hand around herself, which can in turn be followed up with more clock hands that home in on you. She also loves to TeleportSpam, warping away from you to attack you elsewhere while leaving behind some TNT to screw you over. What's more, she can freely float around the arena, keeping herself just out of reach from you while she pelts you with projectiles. Another thing to note is that unlike previous bosses, [[MyRulesAreNotYourRules she can't be grabbed whatsoever, whereas she can and will gladly do it to you]] if given the chance. Lastly, if she fully charges her spinning clock attack, then she'll temporarily freeze time and fire several clock hands at you. Fighting Kronii is almost like fighting [[VideoGame/MortalKombat11 Kronika]] or [[VideoGame/XMenChildrenOfTheAtom CotA Magneto]].
