Big Thwomp

Big Thwomps (also referred to as Super Thwomps) are giant Thwomps that have made semi-recurring appearances throughout the Mario franchise. Although their size varies among games, it is always shown that they are larger than the other Thwomps seen alongside them in the games. They also have the ability to smash through certain types of Brick Blocks and other blocks, something that their smaller counterparts are usually incapable of doing.

Nintendo Adventure Books
In the book Monster Mix-Up from the Nintendo Adventure Books series, a giant Thwomp is created as a result of combining six Thwomps using the Monster Mixer, referred to as "the biggest Thwomp Mario’s ever seen."

Super Mario RPG: Legend of the Seven Stars
A large variant of Thwomp is seen in Super Mario RPG: Legend of the Seven Stars, inside Bowser's Keep. It is the last and largest Thwomp seen in a line of four smaller Thwomps. It is the first appearance of Big Thwomps in Mario games.

Mario Party Advance
In Mario Party Advance, a large Thwomp appears in the minigame Chicken!, where players compete to stand under it as it descends without being crushed by it. The Big Thwomp has the Super Mario 64 design of the Thwomps.

Super Mario Party
In Super Mario Party, Big Thwomps can appear alongside regular Thwomps in the minigame Follow the Money. They are obstacles, and cause the player to lose coins if they crush them. Unlike in Mario Party Advance, the Big Thwomps have the New Super Mario Bros. Wii design.

New Super Mario Bros.
In New Super Mario Bros., they act just like Thwomps as they will come down from the ceiling in an attempt to squish Mario; the only differences are that these enemies have the ability to smash through Hard Blocks one row at a time and are larger in size. They also have the same weaknesses as their smaller counterparts, being able to be defeated by either a Starman, as Shell Mario, or as Mega Mario. Two make their first appearance in, and another one appears in a room in.

New Super Mario Bros. Wii
Big Thwomps reappear in New Super Mario Bros. Wii as well. However, they only appear in. Like in New Super Mario Bros., they are capable of smashing Hard Blocks one row at a time.

Super Mario Galaxy 2
Two Big Thwomps appear in Super Mario Galaxy 2 in the Supermassive Galaxy. They are much larger and wider than normal Thwomps. Mario can still wall jump up them just like the normal ones and also long jump to quickly pass them. There is a 1-Up Mushroom on top of one.

New Super Mario Bros. 2
Big Thwomps return again in New Super Mario Bros. 2. They can be found in and retain the ability to smash through Hard Blocks one row at a time. Big Thwomps are also featured on course three of the Gold Rush Pack.

New Super Mario Bros. U / New Super Luigi U / New Super Mario Bros. U Deluxe
Big Thwomps reappear in New Super Mario Bros. U, where they only appear in the level Wendy's Shifting Castle alongside ordinary Thwomps and Thwimps. Because no Hard Blocks appear in said level, Big Thwomps are no longer seen smashing Hard Blocks. Big Thwomps also appear in New Super Luigi U in the level Wendy's Thwomp Castle, where they are seen smashing through multiple Brick Blocks in one fall.

Big Thwomps reprise both roles in New Super Mario Bros. U Deluxe.

Super Mario Maker / Super Mario Maker for Nintendo 3DS / Super Mario Maker 2
Big Thwomps appear in Super Mario Maker, Super Mario Maker for Nintendo 3DS and Super Mario Maker 2. The player can enlarge a normal Thwomp with a Super Mushroom, turning it into a Big Thwomp. Unlike normal Thwomps, Big Thwomps can destroy Cloud Blocks, Hard Blocks, Ice Blocks, and ? Blocks, and they can also smash through multiple rows of Brick Blocks in one fall.

Mario Kart Wii
A Big Thwomp makes an appearance on the battle course Thwomp Desert in Mario Kart Wii, where one pounds the ground creating earthquakes. This Thwomp can also smash racers if they drive too close while it slams the ground.

Mario + Rabbids Sparks of Hope
In Mario + Rabbids Sparks of Hope, a Big Thwomp covered in Darkmess appears on the back of the Giant Squashette.
