The enemies listed in this table match those in the Super Mario Bros. Encyclopedia.[1] The default order they are listed derives from the official guidebook[2] with adjustments that ensure enemies are listed next to their immediate relatives. Some listed enemies – namely Super Piranha Plant, Mega Cheep-Cheep, Mega Deep-Cheep, and Big Whomp – are not individually listed in the guidebook, but are recognized as distinct in the encyclopedia. The leaping Cheep-Cheep variant named トビプク (Tobipuku) in the guide is lumped with its underwater counterpart in the encyclopedia and this is followed suit here. The blue-shelled Koopa Troopa is not listed in either source.
This small Goomba works the same as its bigger cousins. Only appears in Mini Pipes, and is the only enemy Mini Mario can defeat them with one stomp. Other versions of Mario can defeat them by just touching them.
A basic form of Koopa. The green-shelled Koopa Troopas walk into bottomless pits. By stomping on it, it retreats into its shell. The shell can slide when kicked, and can also be used to defeat enemies or destroy bricks.
This Koopa Troopa has wings. It either flies back and forth or bounces all around. One stomp makes it lose its wings, and turns it into a Koopa Troopa. It can also be defeated by a fireball.
Throws Spiny Eggs and has his own cloud. One stomp and it is defeated, and the cloud disappears. If defeated with a shell or fireball, the cloud stays, so Mario can take to the skies in it for a while.
Spike balls thrown by Lakitus, turning into Spinies upon landing. When a Spiny touches water, its turns back into a Spiny Egg, only returning to normal once the water recedes. Lakithunder's Spiny Eggs instead bounce around the arena.
These hatch from Spiny Eggs. Any stomp, even the Ground Pound, harms Mario. Also found on ceilings, and comes down when Mario passes, but can collide with other moving Spinies and knock each other out. If a Spiny falls upside down from a ceiling, they behave similarly to Koopa Troopas and Buzzy Beetles. Fireballs and the Super Star can defeat them.
A large Hammer Bro that carries sledgehammers. When Mario does not jump, he can stun him. It can be defeated with a stomp, a fireball or a block from below.
Imitates 1-3 bricks and a ? Block, stacked on each other. When Mario approaches, it comes to life and hops around. Easily distinguished by the fact that the ? does not turn. Mario can defeat it by ground pounding all the blocks down to the ? Block.
A brown giant fish, with spikes all over. It jumps for some time, similar to Boss Bass. It can be defeated with a fireball, a Koopa Shell, a Starman, and a Mega Mushroom, but returns after a few seconds.
An eel that lives in gaps, and tries to bite Mario. Occasionally, they can be found swimming back and forth. They can be defeated with a Mega Mushroom or Starman.
A bigger Unagi. Cannot be defeated, but can be swam through with a Mega Mushroom or Starman (except through the face, in which case Mario gets knocked back instead). In World 8-3, one chases Mario at the second half of the level.
Larger versions of normal Whomps that walk around instead of standing in the background. When they fall on the ground, the player can ground pound them to defeat them.
Spits a fireball that follows Mario, causing its tail, made of fireballs, to decrease in length. It self-destructs when it does not have any fireballs left, which can hurt Mario. Can be defeated with a stomp or a fireball.
Approaches Mario if his back is turned. When looked at, it stops to inhale air to grow. Shrinks to the normal size of a Boo when it attacks. A Starman, Blue Shell or Mega Mushroom can defeat Balloon Boos.
Boxing ghoul-like monster. Can break bricks and other blocks that are normally indestructible. Mario can defeat it by jumping on it three times, or hitting it with a fireball.
A hopping pest that at first looks like a coin. Stomp on it or hit it with a Fire Ball to get coins, and if it is jumped on or hit enough times, Mario gets a 1-Up Mushroom.
This spider appears from upwards via its web. One stomp or fireball drops it off its string and defeats it. Also, some can detach from their strings and walk along the ground in World 8-4.
Bowser Jr. is fought in all towers and in World 8-Bowser's Castle. Mario needs to jump on him three times. When he has his bandanna on his face, he hides in his shell when he gets close to Mario, so he needs to jump on the Green Shells he throws and throw them back at him, then jump on him, three times. A ground pound counts as two hits, or Mario can defeat him with nine fireballs, which do not stun him like jumping on him does.
Mario should run around so that Petey tries to squish Mario. If he moves out of the way in time, Petey should slip and land on his back. Mario should then jump on Petey three times to go to World 6 or ground pound him three times with Mini Mario to get to World 7.
