Fake Bowser

The False Bowsers are various species that were transformed by Bowser's black magic. They first appeared in Super Mario Bros..

Super Mario Bros. / Super Mario Bros.: The Lost Levels
Mario has to fight seven False Bowsers (one in each castle) before he can reach Bowser's Castle and fight the real one. Hitting a false Bowser with fireballs reveals that they are really just common enemies disguised as their king with a spell (presumably put on them by Bowser). Some of these enemies are colored light gray (because of the castle's gray color palette), however. The enemies and their attributes are:


 * World 1: Goomba - fire
 * World 2: Green Koopa Troopa - fire
 * World 3: Buzzy Beetle - fire
 * World 4: Spiny - fire
 * World 5: Lakitu - fire
 * World 6: Blooper - hammer
 * World 7: Hammer Bro. - hammer

Super Mario Bros.: The Lost Levels additional worlds:
 * World 9: Bowser - hammer and fire (FDS) / Bowser - hammer (SNES)
 * World A: Goomba - fire (FDS) / Red Koopa Troopa - hammer (SNES)
 * World B: Koopa Troopa - fire (FDS) / Green Cheep-Cheep - hammer (SNES)
 * World C: Buzzy Beetle - fire (FDS) / Bullet Bill - hammer (SNES)
 * World D: Spiny - fire (FDS) / Bowser - hammer (SNES)

The You vs. Boo section of Super Mario Bros. Deluxe:
 * 1-4: Green Cheep-Cheep
 * 2-4: Bullet Bill

In Super Mario Bros.: The Lost Levels, False Bowsers also appear in Worlds 8-4, 9-3, and D-4, along with the real Bowser. Unlike the other False Bowsers, these Bowsers have more of a mint-green body with a brown muzzle instead of the normal color. This type of Bowser is a magical copy of the real one; it also breathes fire and throws hammers in all levels encountered except in World D-4, where it is a Spiny which breathes fire, just like the one at the end of the level.

Super Mario All-Stars
In Super Mario All-Stars, they also lack their alternate coloration and look identical to Bowser. Because of this and the fact that this Bowser is the only Bowser that appears in World 9, players unaware of the original version of the game have mistaken them for the real Bowser. However, one means of distinguishing them from the real Bowser is the music that plays; the real Bowser's music is different.

On a side note, all the False Bowsers in Worlds 9-D only throw hammers in the Super Mario All-Stars remake. Strangely, the real Bowser in World D-4 also only uses hammers, unlike in World 8-4, where he uses hammers and spits fire.

Super Mario Advance 4: Super Mario Bros. 3
In Super Mario Advance 4: Super Mario Bros. 3, a False Bowser appears as a boss in the e-world level "Classic World 1-4", where it plays a similar role to that played in Super Mario Bros., though it looks identical to the game's real Bowser. It is revealed that the False Bowser is a Goomba after being defeated.

Super Mario 3D Land
False Bowsers appear in the Nintendo 3DS game, Super Mario 3D Land. They have Tanooki tails like Tanooki Mario, and they attack in a similar way as in Super Mario Bros., breathing several giant fireballs from a far place and jumping around the stage.

However, unlike in Super Mario Bros., only two False Bowsers appear: one in and the other in. They are also immune to Fire Mario's fireballs and any other projectiles. In order to defeat a False Bowser, Mario or Luigi has to press a switch at the end of bridge to make it collapse and send the False Bowser into the lava. After falling into the lava, the False Bowsers bounce upwards and show their true forms with a Super Leaf beside them. The False Bowser in World 1 is actually a Goomba, and the one in World 5 is actually a Magikoopa.

Mario & Luigi: Superstar Saga
A False Bowser makes a cameo appearance in Mario & Luigi: Superstar Saga. It is seen in a special area inside Bowser's Castle, which is a side-scrolling level imitating a Super Mario Bros. level, and appears at the end of that level. The Bowser appears to be made of cardboard, and Mario must run underneath him and hit the Ax to make him fall.

Mario & Sonic at the Sochi 2014 Olympic Winter Games
A False Bowser appears as a boss in Mario & Sonic at the Sochi 2014 Olympic Winter Games, specifically in the Mario version of Dream Figure Skating. The appearances of the stage and its boss are based off Super Mario 3D Land. He chases the team across a giant bridge, spitting fireballs at them. The team must hits four buttons to cause the False Bowser to fall into lava, where he turns into a Goomba and a Super Leaf.

Trivia

 * Although not discretely noted, Bowser??? in Paper Mario and the Bowser "mech" in Luigi's Mansion used by King Boo may be classified as False Bowsers.
 * The World 3 and C (SNES version of Lost Levels only) False Bowsers are the only Buzzy Beetles and Bullet Bills that can actually be defeated by fireballs.
 * For some reason, defeating Bowser with fireballs at the end of World D-4 turns him into a Spiny. This was corrected in the SNES remake.
 * In the SNES remake of the Lost Levels, the False Bowsers that appear before the end of the stage were given Bowser's normal pallette instead of the minty-green and brown pallette used in the Famicom Disk System release.
