In Pokémon Colosseum, Miror B. is one of the four CipherAdmins. A man with a gigantic two-toned afro (which resembles a Poké Ball turned on its side), garish glasses, and dressed in a golden sequin-studded leisure suit, Miror B. is the definition of "loud and flamboyant." He spoils his Pokémon and would rather spend time teaching them how to dance than fulfilling his duties as a Cipher Admin. An example of this is seen in Pyrite Town, where he basically lets his grunts do whatever they want as long as they leave him alone so he can practice his dancing.
Miror B. makes his first appearance in Phenac City, where Wes and Rui find him "terrorizing" the mayor, Es Cade. He pauses to drop some vague hints regarding Cipher's involvement, then leaves Phenac City to return to Pyrite Town while his personal Peons attack Wes and lose badly.
After reaching Pyrite Town, it is discovered that Miror B. is controlling the town with an iron fist. Having kidnapped Duking's precious Plusle and held it hostage, Miror B. has effectively blackmailed the town's reigning hero into uselessness, allowing the dancing deviant to run the Pyrite Colosseum and hand out Shadow Pokémon with no resistance to his reign. Though Duking's subordinate Silva attempts to foil the scheme by sneaking into Miror B.'s Hideout and rescuing Plusle, he is greatly overpowered by the guards. Fortunately, he is rescued by Wes and Rui, who proceed into the Pyrite Cave and challenge Miror B. After his defeat, Miror B. leaves town and Plusle is returned to Duking, thus freeing the town from Miror B.'s grasp.
Miror B. shows up again at Realgam Tower, where he is guarding one of the keys needed to unlock the path to the main tower. He is later found as an opponent in the Deep Colosseum, as the last opponent of the first round. Revisiting Miror B.'s "dance stage" prior to defeating Evice will reveal a unique Cipher Peon named Mirakle B., who claims to be Miror B.'s successor.
When Wes first confronts Miror B., his Pokémon consist of four Ludicolo and a Shadow Sudowoodo (later replaced by Armaldo), though he uses more variety in his Pokémon during later matches. Miror B.'s battle strategy consists of stalling his opponent, using Rain Dance to boost his Pokémon's abilities while he slowly whittles their HP away with moves like Mega Drain and Leech Seed.
Miror B. is the only one of the Cipher admins to not receive a legendary Pokémon. Alternatively, he is the only admin to have his own theme music, a Latin-styled dance theme, that plays when fought in Pyrite Town and Deep Colosseum. In Realgam Tower, he decides to fight without his theme, and the standard Admin Battle music plays in its place.
Miror B. as he appears in Pokémon XD: Gale of Darkness
Miror B. later appears in Pokémon XD: Gale of Darkness. Instead of his prior outfit, Miror B. now wears a darker outfit styled after Michael Jackson, even featuring Jackson's signature gloved hand, and is even seen Moonwalking on occasion. His battle theme has also changed to a more disco-styled tone to reflect his new wardrobe.
Miror B. is no longer an admin of Cipher, but is instead attempting to set up his own group, Team Miror B., which consists of himself, Trudly and Folly, and is seeking to own all the Pokémon in the world. He is the only character in the games to be known as a Wanderer.
In this game, when a Shadow Pokémon is defeated before it is snagged and its Trainer can't be rebattled, Miror B. will obtain the Pokémon. After the player meets Miror B. for the first time, he obtains the Miror Radar, which alerts him when Miror B. has entered an area. He can be found at any Poké Spot, and occasionally can be fought as an opponent in the Pyrite and Realgam Colosseum challenges.
He also has three set appearances, each with a unique Shadow Pokémon to snag: the first meeting at the Cave Poké Spot where he has a Voltorb, the Outskirt Stand in which he has a Nosepass (though it cannot be snagged in this encounter due to not having the Snag Machine at the time), and Gateon Port's lighthouse, where he will only appear once all other Shadow Pokémon in the game have been snagged. In this final battle, he'll use a Shadow Dragonite, which is mentioned as having been stolen from the Cipher Key Lair and being the last one produced prior to its shutdown.
After his defeat and the snag of his Dragonite, Miror B. escapes once more. As he flees, he finds the transmitter to the Miror Radar in his afro and removes it, unaware as to what purpose it served in his repeated defeats. He can be found afterwards at Club Krabby, dancing with Razzle and Dazzle.
Nosepass cannot be snagged due to the Snag Machine being missing at this time. Nosepass may be snagged later in Miror B. Colosseum and Poké Spot battles:
Miror B. will randomly replace one of the four Trainers in the current round. All his Pyrite Colosseum Pokémon are a random amount of Pokémon chosen randomly from the ones below, plus one Shadow Pokémon that was missed:

"Oh, now aren’t you boys frightfully pathetic? You mean to tell me you were bested by these darling infants? Darling, did you say your name was <player> or something? I so don’t like saying this, but we’re not at liberty to keep your lady friend at liberty. That sweet young thing, she can see things that ordinary people aren’t supposed to see. That just will not do for what we’re planning to do. No, it just won’t do at all. If you don’t like pain, like most people, you can avoid the pain by keeping your nose out of places it needn’t be. Boys! Oh boys!"
"Boys, I shall make my return to Pyrite now. Do remember that I will be waiting for you to return with the little lady. Am I making myself clear? I won’t accept failure from you again, boys. Fuhohoho… Let the music spin! Let’s get it on!"
Speaking with Nascour in Pyrite Town
"Oh yes indeed, Master Nascour! Our plan is coming along in a lovely, peachy-keen way. We have already broken Duking's spirit. We can do as we please at the Colosseum without his meddling. We've been giving away Shadow Pokémon on the sly to challenge winners for gathering data."
"Fuhohoho! This is perking up my spirit and body! I feel like dancing!"
"Okay then...I shall make my return to the cave where my darling Pokémon await my return! Let the music play!"
At his hideout
Before battle
"Yeah, woot! It's about time, darlings! I’m so frightfully tired of waiting for you. Stop the music!"
"Oh, you kept me waiting for so long, I decided to work up a little perspiration! Fuhohoho. But, my, you have been busy being naughty and messing up our plans. It was oh-so-close for everything to turn out just right, just the way we hoped. But I can salvage our plan by beating you, little man. And so... There's time for one last frantic dance before the grand finale! Let the music play!"
When defeated
"I can’t keep up with the tempo! Oh, no, no, what a no-no!"
After battle
"How, how, how dare you! Don't you dare think you'll get away with your latest outrage! One of these days, I will take great pleasure in kicking you about with my elegant dance steps! Oh, and I’m not giving up our Shadow Pokémon plan! Let’s go! Escape!"
Realgam Tower
Before battle
"Fuhohohoh. You've kept me hanging around, <player>. You ruined things in Pyrite for us. But, you know, we're not about to lose over and over to you. This time, I'll win. And I mean it this time. Let the music play! ...Oh, never mind that. We'll battle right away!"
When defeated
"I'm an awesome dancer... But I can't win in battles!"
After battle
"This just won't do! But I'll admit you've beaten me thoroughly. Okay, since I'm done, I'll give you this. Here!
"Think of that as a little gift from our great leader Nascour. Don't leave without it, because you'll get nowhere. But, you know, maybe it'd be for your own good if you didn't go on. Fuhohoho!"
Deep Colosseum
Before battle
"Fwohohoho! So, we meet again! You're not escaping my wrath this time!"
When defeated
"Oh, no, no, no! My tempo is off again! This won't do at all!"
Pokémon XD
Cave Poké Spot
Before battle
"Fuhohoho! Hey, my posse! Have you rounded up Pokémon like I wanted? Hm? Stop the music!
"Sniff... Oh, oh, oh! I sense the pleasing scent of Pokémon, oh yes I do! Maybe you're just a little hood, but maybe you're also one fine Trainer with the goods? How about you get with it and join my posse? Be one of us, and you'll soon be owning all the Pokémon around the world."
Yes: "Oh! I hear your mouth say it, but your heart's not in it. I can't abide that. It's big-decision time; you need to think hard before you choose a life of crime. So, tell me, will you join my posse?"
No: "Fuhohoho! I thought you'd say that! You always had this smell to me, you see, that you would be our enemy. How I deal with a threat is to nip it while it's a bud yet. Fuhohoho! I'll be showing you my power now. Try not to be blown away by a sense of wow! Let the music play!"
When defeated
"You messed up my rhythm! I just can't, no, I just can't do it!"
After battle
"Oh, you, you, you! You make me so angry. I'm seeing red! Don't you dare think this is over! Just you wait and see! One of these days, with my elegant steps, I'll knock you sideways! Let's go! Escape!"
Outskirt Stand
Before battle
"Fuhohoho! Did I hear overhear you talking about me? Oh? Well, if it isn't that super-aggravating little boy who served me a bitter memory at the Poké Spot!"
"Fuhohoho! What perfect timing! For a little exercise after my meal, I'll wipe you out with my elegant steps! Let the music start!"
When defeated
"I shouldn't have done something this strenuous right after eating..."
After battle
"Oh, how dare you! I say, how dare you! Next time, I'll put things right and lay down my elegant steps! Let's go! Escape!"
Pyrite Colosseum
Before battle
"I'm ready and set to go! You can bring it on whenever!"
When defeated
"I was ready, but not enough! It won't be me losing the next time!"
Realgam Tower
Before battle (initial fight)
"With my gorgeously elegant dance steps, I'll send you packing!"
When defeated
"My gorgeously elegant dance steps aren't easy, you know!"
Before battle (rematch)
"Oh, you are unlucky to have to face me! Let the music play!"
When defeated
"You've beaten me through and through and thoroughly, too! This won't do at all, not at all!"
Gateon Port Lighthouse
Before battle
"I, I, I! Want you! Want you! Huh?! Stop the music!"
"Let me wind down the music and take a look! Oh, you are! You are that super-annoying brat! It's all your fault that my Shadow Pokémon is the last of the kind! But you did worse! You messed up my dance for celebrating the future of Team Miror! Today of all days, you're not going to get away! No, you'll never, never get away! Let the music play!"
When defeated
"Battling with you, I can't seem to find the right groove at all."
After battle
"Oh, how dare you! I say, how dare you! That Shadow Pokémon was Cipher's very last Shadow Pokémon! There's only one thing to do now. Let's go! Escape!"
