Article on Super Mario Wiki Thwomp

Thwomps (ドッスン, Dossun) are enemies from the Mario series.


Thwomps made their debut in Super Mario Bros. 3 as a recurring enemy, and has become a recurring enemy in later Mario games. They are rock-like enemies known for their stone faces. They normally remain stationary in the air, but when they are approached by the player, they attack by falling on anyone attempting to pass underneath them. They are often found in castle levels and have a variety of subspecies such as Thwimps, Tox Boxes, and Whomps.

Thwomps spend most of their time suspended in midair, waiting. When Mario passes below, they crash down with amazing speed. As you may guess from their appearance, they're heavy and solid enough to make any attack on them futile. Small ones are called Thwimps: despite their weight, they often form groups and bounce around.

The Thwomp trophy is exclusive to Super Smash Bros. for Nintendo 3DS.

NTSC You can't reason with a Thwomp. If you get close enough to try, it will just drop down to block your path. In fact, you can count on Thwomps to always do exactly that—they've gotten really good at it. A Koopa I know swears they work great as a home-security system...
PAL Have you ever wondered what it would be like to have a Thwomp of your own? If anyone tried to break into your house, it would just go "THWOMP!" right on their head. Yep, a Thwomp would make a great home-security system. Unfortunately, they're not available in shops. Sad times.

In Super Smash Bros. Ultimate[edit]

As an Assist Trophy[edit]

Thwomp debuts as an Assist Trophy. It was revealed during the Super Smash Bros. Ultimate Direct in November 1, 2018.

During the reveal trailer, Thwomp is first seen attacking and launching Kirby, who attacked Snake using his Thwomp Stone transformation on the Garden of Hope stage. The Thwomp is next seen on the same stage at its center pitfall, falling and failing to damage Mario as he crosses the gap, but succeeding in attacking Luigi.

As an Assist Trophy, Thwomp teleports near or above a nearby opponent. It hangs in the air and falls down when an opponent passes under it, falling through any soft platform beneath it and dealing 32% damage and 10 shield damage. Touching one at rest deals 7%. Unlike its game appearances, however, the Thwomp will teleport to a different part of the stage if left stationary. The Thwomp has a high jostle priority, making it very difficult to pass through without dodging. While Thwomp can't hurt its summoner, it will still push them out of the way and attacks will clang against it.

Training Mode describes the Thwomp Assist Trophy: Squishes opponents caught beneath it. Can't be KO'd. They cannot be summoned on the 3D Land, Big Blue, Dream Land GB, Great Plateau Tower, King of Fighters Stadium, Mario Bros., Mishima Dojo, Mushroomy Kingdom, Pac-Land, Rainbow Cruise, Summit, and Wrecking Crew stages.


Thwomp also appears as an Advanced-class support spirit. It can be summoned using the cores of Rock Pikmin and Rocky.

  • Despite Thwomps having a singular voice clip from Super Mario 64, which is reused throughout the Mario series, they remain mute in Super Smash Bros. Ultimate, possibly to reflect their appearance in the New Super Mario Bros. series, where they are consistently mute.
  • Thwomp's Assist Trophy reveal is very similar to King K. Rool's fighter reveal. While King Dedede was disguised as K. Rool, only to get smacked by him later, Kirby follows suit by using Stone to take the form of Thwomp, only to get hit by a real one.
