Kaiju Big Battel: Fighto Fantasy is 16-bit styled RPG featuring turn-based combat, plenty of exploration, and a funky soundtrack to pump you up. This is an officially licensed game based on the live-action monster wrestling group Kaiju Big Battel, who have been performing their Godzilla-meets-WWE act for over 20 years.

Designed for Kaiju fans and newcomers alike, Fighto Fantasy takes players on a quest across time and space as they work to undo damage caused by the evil Dr. Cube as he rampages through history in search of fame and glory. With seven main playable heroes (and a secret one to unlock), players explore six time periods and punch out dozens of deadly monsters.

All the world is watching as the Kaiju Big Battel Title Fight is about to begin: The diabolical Dr. Cube vs. the patriotic pugilist, American Beetle! Things take a sudden turn when Cube pulls out a secret weapon that rips open portals into history. Now it's up to the Kaiju Heroes to pursue Cube across the centuries, from Egypt to Rome to Russia and beyond! Is the mad doctor pursuing dangerous artifacts lost to time, or does he just want to deface famous landmarks with his own ugly mug?

⚫ Combat: No random encounters here; touch enemy NPCs on the map to trigger turn-based battles. Each of the seven main heroes has their own strengths and weaknesses.
⚫ Side stories: When you're not chasing Dr. Cube through time, take a minute to help out some locals. Slay a musclebound mummy, rescue lost Kaiju heroes, adopt cats!
⚫ Map abilities: Each hero has a unique ability to interact with environmental objects, unlocking hidden paths and secret treasures.
⚫ Difficulty selection: Easy Mode for a relaxed experience, Normal Mode for players who want some tense fights, and Hard Mode for players looking for more deadly dangers.
⚫ 12+ hours of RPG adventure.

I really enjoyed the game and included it in my second Hidden Gems Video. A like/subscribe would help me a ton to continue with this series <3

Another great find, a decently sized RPG (12 hours-ish) with an original theme that finally gives a good reason for oversized sprites on the map (you are a giant monster/robot after all). The underlying RPG system are fairly standard, but the world with plenty surprises, characters and just pure insanity of the setting makes this a clear recommendation to check out. 4,5/5

More Racial Justice Bundle impressions:

Thank you for playing!

Hi, there's a bug on the Android version I want to bring to attention... I'm not sure what causes it, but sometimes the down direction will stick, and it's impossible to move in any direction. Not only that, but it continues in the menu, with the selection continuously scrolling down. I don't know what triggers this bug but I have to restart the app to fix it, which is an issue if I haven't saved in a while.

Thanks for the report! I haven't seen this one but will look into it ASAP.

Can you let me know what kind of phone/tablet you're playing on?

I'm playing on a Samsung Galaxy Note 9.

Pretty good overall, but is there any way to change the default key configurations? Placing action and cancel so far apart is less than ideal. RPG Maker uses Z and X, which is really nice on a QWERTY keyboard. It would also be nice to get an explicit message when you hit a weakpoint or resistance like RPG Maker VX does, if that's possible.

I can't seem to find Dusto's ultimate skill, unless he doesn't have one? The only sidequest I have left is the superboss, which I can't figure out how to beat. I also seem to be missing one of Robox's status skills, the one immediately below Corrode. (I may also be missing other skills of his, unless not all of them complete a line.)


Hello! There's currently not a way to change key configurations but it's something we want to add in the future.

Dusto's ultimate skill is hidden in Hero HQ and involves an object you can examine in the HQ kitchen.

That Robox skill can be learned from the Bear Ranger in Boston.

Thank you for playing!

Ah, I didn't realize that object did anything! I enjoyed it, very funny.

The Bear Ranger gives Whip It, which is the skill down and to the right of Corrode.


Whoops, I misread the original message! This is his final spell list for that category. If Slap is the spell you need, it can be learned from Monger Kingu, one of the minibosses in The Abyss. You can refight him in the cavern path leading to New Abyss City.

I actually tried to refight that enemy as soon as I regained Robox, but it doesn't seem to respawn.

Can you rest at the New Abyss City warp point and then check on that enemy again? If that doesn't respawn it, it's a bigger bug I'll have to look into. Thank you!

Game's a silly and fun blast all the way through. I don't usually play RPGs, but this has just so much fun charm in it. Even if I'm not familiar with the license this game is based on, it's still fun on it's own, even if it can be hard sometimes


Thank you!

Wonderful RPG, really enjoying it! Left a 5-star review :) Thank you so much for including it in the bundle! It's great to discover hidden gems that I probably never would have found out about otherwise!

Thank you for playing!

Really fun game. Runs great on my phone.


No. Thank you!!

This game is amsome. i love so much this game and finished That

Thank you!


Hello, the linux version of the game gives me this error "Exit code 0x7f (127)" when trying to start it in the itch.io launcher, try to run it from outside but it does nothing.

Do you have any idea what the problem may be?


First I've heard of this, I'll take a look into it and let you know!


I've uploaded new Linux builds for 32 and 64 bit binaries, please let me know if you're still seeing this error!

Keep getting the same error from the itch launcher.

I have tried to run it from the terminal and I get the following:
/.config/itch/apps/kaiju-big-battel-fighto-fantasy/kaiju-linux/kaiju: error while loading shared libraries: libSDL-1.2.so.0: cannot open shared object file: No such file or directory


I reached out to my engine developer and this was what he had to say, I hope this helps!

"That means that the Linux system does not have SDL 1.2 libraries installed. Almost all Linuxes will have a package available for SDL 1.2 since it is a popular library for a lot of games.

If they have Debian or Ubuntu or a Linux from that family they should look for a package called something like libsdl-1.2

For CentOS or Redhat or a Linux from that family, should look for SDL-1.2

Also it is worth mentioning that SDL 2.0 will not work. The newer version of the library is not backwards compatible with SDL 1.2 (but it should always be possible to install both versions at the same time. They do not conflict)"

(1 edit)

Ok after installing sdl1.2 library from several different packages I have got it to work.

Can we also get the android game uploaded here? If that's possible?


Sure! I've also added the Mac build.

Sick! You're the best. 

This looks awesome. I just ran across it. But payday isnt till friday. Hope I remember this then. <3

Thank you!


Hello! Is it possible to purchase the Linux version on itch.io? It seems to be available on Steam but not yet here. Thank you!


Hi! The Linux version should be available now. Please  let me know if there are any issues, thank you! (Wait until October 30th if you're going to buy though, there's a sale launching for the game's first anniversary.)


That's so nice! Thank you so much!!
