Ex is the Guardian of Time and Space, and the former King of Tetris. He is also the true father of Ess.
Puyo Puyo Tetris
His presence is first foreshadowed in Chapter 6. During Ess's visions while training, she encounters Zed. But instead of Zed's normal behavior, she hears a message from a mysterious voice, talking about regretting leaving Ess alone and creating Zed as a substitute. Distressed, Ess challenges Zed to a match, afterwards shrugging it off as an impostor. However, he would appear to O, saying that he's the one that receives Tee's reports and apologizes for causing the worlds to merge with each other, requesting for O to stop him.
His proper appearance is in Chapter 7. Tee explains that he sends the reports to Ex via O, but doesn't remember it. Ex explains it's because of the Edge of Reality exists within Space and Time, meaning he technically didn't exist in any particular world. Arle, Amitie, and Ess then interrupt the conversation to make Ex fix reality before the universe is destroyed from the worlds merging together. However, Ex says it's too late to fix it, and runs off. He then explains that he was once the King of Tetris, before gaining the ability to transverse, and as such became the guardian. He resolved to protect the boundary of reality, using the reports from Tee and O as his only form of communication. However after countless years have past by, he started to develop a sense of depression from the loneliness, eventually causing him to neglect his duties out of doubt and cause the worlds to start merging with each other. Eventually at the Edge of Reality, he personally requests Tee to beat him in a match, believing that being defeated by the current King of Tetris, Tee would motivate him to protect the boundary once again. After beating Ex, Tee requests to take Ex's place as the Guardian due to his loneliness, but Ex personally rejects it. Tee then challenges him again, this time with Ex's full strength. Ex loses, but eventually after persuasion, Amitie comes up with a plan to allow Ex to travel out of the dimension, with assistance from Satan and Ecolo.
As a playable character, he uses the same AI and dropset as Ms. Accord when playing Puyo. Unlike the other characters introduced in Puyo Puyo Tetris, he meets Ms. Accord personally, as revealed in Chapter EX10.
