Ex

**Ex** is the current Keeper of Dimensions, the former Tetris King, previous captain of the S.S. Tetra, and the true father of Ess. He represents the crossover between Puyo Puyo and Tetris and serves as the true antagonist of Puyo Puyo Tetris.

He is called "Keeper" by Tee, "Mr. Fancy Suspenders" by Ringo, and "old man" by Feli.

He is voiced by Matthew Mercer.

## Appearance

Ex is an older man with yellow eyes, gray hair, and white stripes in it that form the shape of an "X". He wears a frilly white shirt, a pink bowtie, and yellow suspenders with brown straps, with the straps' ends hanging loose.

## Relationships

### Ai

Ex adopted Ai when he was a puppy and raised him. Ai looks up to him and sees Ex like a father.

### Dark Prince

Ex calls the Dark Prince "long green-haired man" because of his appearance since they're both antagonists. He also thinks of him as his buddy due to the fact that the Dark Prince calls him an "old goofball".

### Ess

While Ess is Ex's biological daughter, she is estranged from him and doesn't see him as her actual father.

### Feli

Ex calls Feli "young lady" due to the fact that Feli calls Ex "old man" because of his appearance and their age difference and the fact that Ex is an antagonist and Feli is a deuteragonist/protagonist. He will most likely get hit by Conjunction, Significator, and Principal Star by Feli knowing that his spells are no match for Feli's spells because Ex's spell Revolution sends out flowers.

However in the episode Blue Boy and Grey Man, he was handcuffed by Feli using containment cuffs in the city of New York and their picture was taken by The New York Times afterwards.

### Sig

Due to his estrangement from his own daughter Ess in his own family, he tries to make Sig his son and the next Keeper of Dimensions due to the fact that Sig attends Primp Town Magic School because Klug and Feli always try to stop him because Ex is trying to put his family back together thinking that Sig is Ess' brother as he's trying to call him "Keeper Junior". He also thinks the jacket on Sig is much better than the t-shirt.

However, his plans to take him have failed in the episode Blue Boy and Grey Man due to Feli, Klug, and Lemres intervening creating a diversion in the city of New York to stop Ex in his tracks.

## Trivia

* Ex's name refers to the crossover between Puyo Puyo and Tetris. This can be seen in the "X", or *cross*, shape in the backgrounds of the title screens of both *Puyo Puyo Tetris* and *Puyo Puyo Tetris 2*.
	+ In fact, his hair contains a white "X" overlay that perfectly matches the shapes in these backgrounds.
	+ He may additionally be named after the X pentomino (although such piece is never present in either game he appears in).
* Alternate Voice notes:
	+ In *Puyo Puyo Tetris* in both Japanese and English versions, his tone becomes more rough.
	+ In Puyo Puyo Tetris 2, he speaks in a quiet, hoarse tone.
		- In the English version, most of his alternate voice clips are reused from the original Puyo Puyo Tetris, and his new voice clips retain the same tone.
* Ex is referred to as both X and MST in the game's files. MST is most likely a contraction of **m**y**st**ery, possibly to prevent spoilers or as a placeholder until his concept was finalized.
* He's the only character introduced in Puyo Puyo Tetris that is not based on a Tetrimino.
* Ex's voice actor Kazuki Yao who previously voiced the Dark Prince in *Puyo Puyo CD* and *Puyo Puyo CD Tsu*.
* Another Keeper of Dimensions Yoggus, was shown in Madou Monogatari Saturn. Like *Puyo Puyo Tetris*, the game also involves a journey to the Edge of Spacetime. Whether or not they are related is unknown. However; it is possible that Yoggus was a previous Keeper of the same lineage, as he was slain by Ragnus the Brave.
* Oddly, in the English version, when Ex clears 5 or more lines of Tetriminoes simultaneously in Fusion or Party, he says just "Tetris" as if he cleared 4 lines instead of "Tetris Plus" as usual. Interestingly, the line is said in a way still differs from the regular Tetris, as well as in the title screen.
