Johnny Test (DMU)

In the Dark Mirror Universe, Johnny Test was a member of the Pennis And Also Dicke And Balls Bureau before being transformed into Joey.

Chapter 13: Never Say Don't Ever Again
Johnny Test had been a member of the Pennis And Also Dicke And Balls Bureau for some time before the Dong Squad arrived in the Dark Mirror Universe. He and the other PAADABB members defended the Dongers from Kek when they saw the tyrannical entity attacking the strangers. Once they had all gotten to know each other, Johnny suggested that they return to the PAADABB's base, Panus and Asenis, to relax, compare notes, and prepare for the next fight.

Later, Johnny saw Ainsley Harriott and some LGAMs carry some special mutation spaghetti into the base. Upon being told what it was, Johnny insisted that they test it on him to see what happens. Ainsley was hesitant at first, but eventually agreed, on the condition that he couldn't be held liable for what happens. Ainsley then strapped Johnny to an operating table while he gathered ingredients for the "recipe". One of the ingredients he found was a sample of Coach's DNA, prompting him to ask Johnny what it was; Johnny told Ainsley all about Coach and what happened to him. After hearing this, Ainsley secretly added it to the recipe, along with another vial labelled "Bob Frumm Food-Use". The ritual that Ainsley performed while mixing the recipe scared Johnny quite a bit, but this was replaced with excitement once it was completed. Johnny eagerly consumed the resulting pasta dish, but was immediately painfully transformed into a mutant named Joey, who seemed to have a different mind altogether.
