Developed in 1989 by Creator/VICTokai and released by Sega for the SegaMasterSystem, ''Psycho Fox'' is often considered the Master System's answer to ''Franchise/SuperMarioBros'', as it takes more aspects from said game than the more famous ''AlexKidd in Miracle World'', while still being different enough to be considered a CultClassic in some cases. The game was based on the [[NintendoEntertainmentSystem NES]] title ''Kid Kool'', but refines many of the problems present in said game.

The player controls a {{Kitsune}} who has the ability to transform into other animals (a monkey, a tiger and a hippo) in order to put an end to the turmoil that the evil Madfox Daimyojin has caused to the world.

A [[SegaGenesis Sega Mega Drive]] game using the same engine and formula was released under the title ''Magical Hat no Buttobi Tabo! Daibōken'', which was localised as ''VideoGame/DecapAttack'' in the west.

!!Tropes in ''Psycho Fox'':
* OneUp: The player can obtain these by breaking certain eggs scattered across levels. The 1-ups appear in the form of ghost versions of the characters who constantly run to the right. If not collected in time, they run off-screen and cannot be obtained.
* ThreeQuartersView: The bonus stages play in this view.
* AwesomeButImpractical: The hippo is the only character that can break certain walls that lead to alternate paths. To compensate, however, he is much slower than the other characters and cannot jump as high.
* BigBad: Madfox Daimyojin. He is also the FinalBoss.
* BonusStage: Collecting money bags during levels takes you to a bonus stage called ''Amida''. The stages consist of five paths that the titular character can take; the more money bags you have collected in a level, the more paths you can take. The paths lead to different goodies, except for one, which leads to a pit and gives you no bonus.
* BubblyClouds: Stage 4, Wind Zone, mostly consists of these.
* ChestMonster: Eggs sometimes contain enemies instead of useful items.
* CowboyBebopAtHisComputer: The UK magazine ''Computer and Video Games'' refers to Psycho Fox as "Charlie Fox" and Birdfly as "Jimmy the crow" in their review of the game. They also imply that he's being fox-hunted and that he must reach the final level before he can "win the respect of the huntsmen".
* CutAndPasteEnvironments: Zone 4 (Wind Zone) largely consists of the same graphics as Zone 1 (Mystical Mountains), but is set in the sky.
* DolledUpInstallment: The Brazilian release was called ''Sapo Xulé: Os Invasores do Brejo'', based on a Brazilian comic strip, which replaces the existing characters with characters from the comic.
* TheGoomba: "Pockly Guy".
* GreenHillZone: Despite its name, Zone 1 (Mystical Mountains) fits this trope fairly well.
* InvincibilityPowerUp: bottles of "Magic Medicine" appear inside eggs and the occasional enemy. unusually, you don't get the invincibility straight away but it must be activated via the pause menu.
* NoExportForYou: Inverted. Despite being developed in Japan and incorporating aspects of traditional Japanese culture, the game was never released there, largely due to the Sega Master System not being a huge success in the region.
* PrecisionGuidedBoomerang: Once Psycho Fox finds Bird Fly, he can sic him on enemies this way.
* RatchetScrolling: done horizontally.
* RecurringBoss: All bosses except for the final one are used twice.
* ShiftingSandLand: Stage 3, Diabolical Desert. Some of the level takes place on sand, and other parts take place on stone. When your character is walking across sand, he will lose speed.
* SlippySlideyIceWorld: Zone 6 (Ice Zone)
* SmartBomb: The Straw Effigy destroys all enemies on screen when activated.
* SoundtrackDissonance: There are only three level tracks in the game. The fifth, sixth and seventh (final) level share the same theme, so the spooky underground cavern level at the end of the game has [[http://www.youtube.com/watch?v=eegB8EhUG1k This cheery number playing in the background.]]
* TyopOnTheCover: Early releases of the game have "Psyco Fox" printed on the cartridge.
* UndergroundLevel: There are two: Stage 5 (Underground Passageway) and Stage 7 (Underground Cavern).
* VoluntaryShapeshifting: a PowerUp called a "Psycho Stick" will allow Psycho Fox to transform into a monkey, a hippo or a tiger. All characters have different attributes. The fox is an all-rounder with no specific skills, the monkey can jump higher, the tiger runs faster than the others, and the hippo has the ability to break certain walls but cannot run or jump as high as the other animals.
* WarpZone: These are normally invisible. The only way to tell where they are is to throw Birdfly (a weapon in the game) and see whether he lands or runs into what appears to be nothing. If so, Birdfly has to be repeatedly thrown at this space until the warp zone appears.
