Digimon Battle Spirit
Digimon began as a line of toys in 1997. People could buy digital pets to take care of. Soon, the company grew to include anime, trading cards, and a lot of RPGs. As soon as the games came out, there were also fighting games. Digimon Battle Spirit was the first fighting game that wasn’t part of the main series. It came out on the Game Boy Advance.
Digimon Rumble Arena came out on the PS1 in 2001, the same year it came out. The way you play both games is similar to how you play the Super Smash Bros. games.
Dissidia: Final Fantasy
Final Fantasy is one of the most popular RPG series out there. So, it seems likely that Square Enix will make at least one fighting game spin-off in the future. This spinoff game is called Dissidia: Final Fantasy, and it started on the PSP.
So far, there have been three games in this sub-series. They all have enemies and heroes from other games in the franchise. Have you ever wondered who would win if Cloud and Squall fought? Now, players can fight in real time to live out these battles.
Granblue Fantasy Versus
Granblue Fantasy is not a very popular name in the West. This is because the first game in the series came out in Japan in 2014 as a mobile game. There, mobile games in general and RPGs in particular do much better.
Recently, spinoffs have been used to try to get more people interested in this brand. Granblue Fantasy Versus was the first. It was a 2D battle made by the experts at Arc System Works. It didn’t do as well as their other games, like Guilty Gear, but fighting game fans liked it.
Persona 4 Arena
Persona 4 Arena was the first big spinoff that wasn’t an RPG in the Persona series, and it got things going. From Dynasty Warriors, there are now both dancing games and action RPGs. The best thing about Persona 4 Arena and most of these spinoffs is that they are considered canon or at least are based on official material.
Backrooms Game had all of the available characters from the first game, as well as guest heroes from Persona 3 who had grown up. For example, Ken was no longer a small child.
Pokken Tournament
Since Super Smash Bros. came out on the N64 in 1999, Pokemon has been a part of fighting games. Decades later, they would be able to play Pokken Tournament on the Wii U, which was a more pure fighting game. Fighting is one of the types of elements in the games, so it made sense to make it.
Fighting-type Pokemon were the only ones in the game, but Pikachu tried to wrestle with the best of them as well. It wasn’t nearly as famous as Super Smash Bros., but it was interesting to see Nintendo and Game Freak branch out to more developers and game types.
Super Smash Bros. Ultimate
The latest fighting game in that series is Super Smash Bros. Ultimate. It has characters from all of Nintendo’s names, but it also works with third-party games. Even though it might be cheating to say this, you could call it a spinoff of Fire Emblem.
There are a lot of characters from the series in the game. There are eight of them, not counting alternates or outfits. So, it’s a fighting game spinoff of Fire Emblem in the same way that any other Nintendo title is.
Tales Of VS
The game Tales of VS was never released in the West. It came out for the PSP in 2009. Tales of VS had four-player battles with characters from all of the Tales of games up to that time, including Tales of Vesperia.
Even though you can’t fully enjoy it in English, text doesn’t make it hard to get into as a fighting game. Also, some internet work has been done on an English fan patch.
Ys VS. Sora No Kiseki: Alternative Saga
Ys VS. Sora no Kiseki: Alternative Saga is a PSP game that is not a spinoff of just one great series, but of two. It put characters from all of the Ys games and The Legend of Heroes: Trails in the Sky against each other.
Nihon Falcom didn’t post the game to the West after it came out in Japan in 2010. Both titles aren’t as well-known outside of Japan. The game is played from the top down, like Power Stone. It has some English fan fixes online, just like Tales of VS.
