Mr. Y

Mr. Y (From the Celestiale Dimension) is the friend of Mr. M and Mr. L just like Yoshi is the friend of Mario and Luigi. Due to taking over Yoshi the SSM is stuck in his mask form.
== History ==
=== Background ===
Just like Mr. M and Mr. L, Mr. Y came from the Celestiale Dimension. However, unlike them, he was not in a pocket universe before coming to the Mushroom City Car Wash universe. Instead, he walked about the remains of the Celestiale Dimension. For he was with the three Mr. Js during the time of Mr. L and Mr. M’s last prank, as he did stuff for the Mr. Js because he was a hero of the land, as he was most like unto the Yoshis of other universes that other Mr. Ys. He was also white before becoming red due to the color of Yoshi the SSM. Just before he was introduced in the universe, he took control of Yoshi the SSM when 3D Nastasia mind controlled him when he went there to rescue Officer Dark Light (known back then as Official Baby Luigi and Black Baby Luigi) but was caught by Mimi that disguised herself as him to get him into a cell on post 1367.
=== Adventures in the Mirror World (introductory) ===
After the attack on the Random Castle with Bowser in it, a Glooper Blooper started attacking people. However on post 1505, Mr. Y appears and defeats the Glooper Blooper. After learning of spheres, he goes away from everyone, as they destroyed one of the spheres. During his absence, he and Bowser went to the Mirror World and Bowser used him to get the Cloudy Relic in the space part of Light Land, which he was unhappy about. He then battles Bowser with others that have come to Light Land and takes the Cloudy Relic from Prince Kiwi and goes to Clock Lazy Tower. After arriving at Clock Lazy Tower, he got off of Yoshi to avoid being caught by the group and hid the Cloudy Relic inside of him to avoid it being taken back. After Yoshi the SSM goes into an office, he becomes Mr. Y again and befriends a duplicate of Prince Kiwi. He later befriends the real Prince Kiwi and helps him out reopening up his castle. Eventually, he introduces Count Blumieres, 2D Timpani, and 3D Nastasia, his friends, to Prince Kiwi. After encountering Skynet 2.0 and seeing him take relics, he uses his POW Relic on him. And when Skynet 2.0 retaliated, Mr. Y dropped a fake POW Relic which contained a virus to take out Agent Smith and was critized for it by White Lightning's people. And after Mr. Y got rid of the viruses, a malfunctioning mechanical shark went after Flora which causes harsher critizium from White Lightning's people so that they and even try to hurt him, which he refuses to retaliate due to the presence of the Pixl Queen. Mr. Y would later defeat the Pixl Queen by turning Pixls against her and then giving her a hug. After a while, he reveals himself as Yoshi the SSM who causes the demon inside the Pixl Queen to leave and made the Pixl Queen human again.
=== Trial of Flora ===
Mr. Y reappears again after being summoned to testify in the trial of Flora. It was because she was of White Lightning's people who wanted to hurt Mr. Y. After being asked a few questions, and even explained why Flora even threaten him in the first place before getting off of the stand. He even allowed Yoshi the SSM to overhear the court. The next day, Investigator Toad learns that Yoshi the SSM was hypothesized and was the same person as Mr. Y and decided to use him to compare him to Flora, which he found to be the same albeit from a different person.
== General Information ==
=== Physical appearance ===
Mr. Y is a Red Yoshi with black shoes, a black shell, and a mask. At least, that is his full Yoshi form. His consciousness is in the mask. This mask is almost identical to the masks Mr. M and Mr. L use.
=== Personality ===
His personality is like unto most other Yoshis. The main difference is that he likes to help out villains with plots. But, he doesn't do so with all villains. But even still, when he does not do that, he helps out others like any other Yoshi would do.
=== Powers and abilities ===
The Yoshi is capable of doing many things. Like Yoshi the SSM, he can use his tongue, throw eggs, and spit of fire. He is also skillful in ninja skills. He also gain the power to travel to other universes when Yoshi the SSM gave them to him via the Chaos Emeralds.
As for the mask, he has the ability to float in the air, but choses not to because he can only do so when he is just a mask and he still likes being a Yoshi. This was one of two reasons why he left Yoshi the SSM and found another Yoshi, the other being that Yoshi the SSM would not always want to be controlled by Mr. Y. He can also take control of other people, making them look like their Mr. version. This can be anyone, even dead and wounded people, as they will appear to be fine as long as he is on them and when he gets off them, they return to what they used to be with whatever happened to him while in him. However, he can't kill the current person he is on.
=== Relationships with other characters ===
He is very close friends of Mr. M and Mr. L and spends most of his time with them. Although, sometimes he can be caught with other things to do. However, he still tries to be with the Bros.
Due to him being linked with Yoshi the SSM, both of them are quite good friends and would do favors for him willingly.
