Shūchō no German

Shūchō no Geruman is one of the major antagonists of the first act in the Super Mario Land 2 manga from the Super Mario series published by KC Deluxe. He is the chief of the Tetris tribe and guardian of their kingdom.

He is a tall dark-skinned human, wearing Aztecan-like clothing, including a feathered headgear that only he has, symbolizing his leader role. As a member of the Tetris tribe, he is capable of changing form from human to a Tetrimino with human limbs and face (a yellow I-Tetrimino, in his case).

Mario, Princess Peach, and Goro-chan, in search of the fabled treasure of Tetris, find its temple, along a Goomba, a Lakitu, and a Hammer Bro that were following them. They all barge in the temple, where they are welcomed by Geruman to try his people challenge to access the treasure: the challenge consisting in a real-life Tetris match with Tetriminos falling from a waterfall, on top of which he stands on a platform, giving order to his people to trow in Tetrimino and monitoring everything. Geruman also explains that failing the challenge might lead them to end up just like Luigi, who, earlier, tried the challenge, and he is now in a comatose state at the bottom of the waterfall's basin.

The Koopa Troop trio goes first and uses the Tetriminos to create a stair to the top, only to be eaten by a statue that will then take them to other losers of the challenge, and turned into slaves. Thanks to Luigi notes, Mario puts together that, to pass the challenge, they need to clear 100 blocks. While Mario and his friends are progressing the game, Geruman is enjoying himself a manga, until one of his men informs him that the heroes are winning. Scared that someone could put their hands on their treasure, Geruman attempts to flatten Peach with a boulder, but Goro-chan saves her (but also falling into the basin and getting itself eliminated). He then laughs at Mario when he remains alone after Peach sacrifices herself by taking the place of a T-Tetrimino. This insult ends up costing him dearly as Mario, using Peach's ribbon as a whip to better guide the Tetriminos into position, latches Geruman's wrist and pulls him down in a gap, as a replacement for a I-Tetrimino, clearing more lines that makes him pass the challenge, bringing his friends and Luigi back into the game.

As the group enters a newly opened passage, Geruman emerges from the ruble, in I-Tetrimino form, and follows them. As the heroes learn of his new form, they mock him and bully him. Angered, Geruman activates a ceiling trap, but his new tall form prevents the spiked ceiling to fall on the heroes. Instead, due to the pressure, the floor collapses, and they all end up into the canal system. Mario and Geruman are separated from the others and arrive in a room where they meet King Tetris, the first ruler of Tetris, who Geruman treats with respect, unaware that he is just Bowser under a disguise. Geruman, being asked by the King to give him the treasure, takes him and Mario to two waterfalls where they will face each other in a Tetris duel. Geruman, once again, cheats by helping King Tetris by telling him which Tetrimino are about to fall next for him, much to Mario's displeasure.

Luigi, Peach and Goro-chan ends up on top of the two waterfalls and the latter ends up cutting off King Tetris', letting Mario clearing the space accumulated in peace. Geruman attempts to fix the situation, ordering the three to leave immediately. When they refuse, Geruman orders him men to turn into Tetrimino and fuse together into the Gattai Tetris Ningen, scaring them away from the waterfall. Luigi then, using some nearby mine carts that the slaves fill with Tetriminos for the challenges, kick it at the monster, destroying it and presumably killing the people forming the amalgamation in the process, since none of them reappear later.
