Calli Kent (the former Clark Kent a.k.a. Superman) could no longer fly (she could maybe slow her own fall if she fell from somewhere, or extend how far she jumped) use X-Ray or Heat Vision (she did still have super-humanly acute senses, just not as extreme as before...of course before she could hear atoms scraping together or what someone was saying on the far side of the continent, so even a VERY watered down version of that was still pretty potent) she was faster than any Olympic athlete could ever be but not faster than a speeding bullet; however even just a faint echo of her former strength and invulnerability meant she was THE strongest individual in the prison...
She still had true, indisputable super-strength, unlike most super-strong types who were left being simply “enhanced” at best. SHE was still strong enough that if pushed she could (combined with the remnants of her other gifts) rip her way out of the prison through main strength; not that she would, or that it would do her any good if she did, she WASN’T strong or fast enough to PUNCH her way through dimensional barriers after all.
Her status meant however that she could go anywhere in the prison with impunity...which was exactly what she was doing now, as she happily skipped down a corridor; Calli’s hair was done up on either side of her head in pony tails, using the prettiest yellow ribbons, her skin tight blue tube top struggled to contain her jiggling F-Cup jugs while her super-short bright red Ra-Ra Skirt flounced with each skip, giving the occasional glimpse of her tiny white thong.
Her BIG, sapphire blue eyes shone with simple minded happiness...
And this was the OTHER reason that she was free to go where she liked without fear...the shock of his fall from grace, combined with the shock of his transformation and the surge of new feeling he was experiencing had destroy Clark’s mind...leaving behind only Calli, a sweet, innocent, VERY horny young girl who even Superman’s most vicious and evil enemies had a hard time being mean to...indeed the entire prison, even the various factions and cliques, had basically adopted Calli as their mascot and were VERY protective of her...people who made Calli cry really didn’t do well in the Playpen....
