In the sonic universe
Backstory time away! Sort of connected to the prior story Miles Tails Prower, ladies' man, the effects have gone away because (as river song says, spoilers!) N.I.C.O.L.E., thankful for letting her keep the body after making him her bitch is now his lab assistant, also I don't think I mentioned this before but they all live in this manor the town gave them because of all their good deeds in the past.
IN THE LAB UNDER THE GANG'S MANSION
"NICOLE! NICOLE! Come here quick!" Tails yelled, his lab coat flailing in the wind as he ran from computer to computer, glancing momentarily at the Dr. Eggman trapped in carbonate, smiling, then continuing to run in big circles until running into NICOLE's… nice breasts. NICOLE looks down at him saying, "Reminds you of old times don't it, remember the 'experiment'?" "Maybe later Nicole," Tails murmured blushing furiously ."but look! A disturbance in the dimensional rift!" "WOOOOW. " Nicole replied sarcastically. "Is it any different from the other BILLIONS that have happened?" "Yes" tails responded angrily "but THIS ONE has organic life in it!" "Once again Tails, woopde doo. Maybe blaze has come over for a visit." Nicole said in an annoyed tone. "Eh maybe you're right," Tails replied quickly, other things being on his mind. "Now what about that experiment you were talking about NICOLE?" he added with a sly grin. "Come on duffas." Nicole said as she took his hand and pulled him towards the bedroom.
