I said it the last time you posted this, I'll say it again, Boy!Cheetah just strikes me as being Jimenez writing a deliberate reversal of the "Female takes on male characters identity for no apparent reason other than mandated diversity" and I never felt it was supposed to be a permanent replacement.
And I could be wrong here, but wasn't it Jimenez who had Ballasteros killed when he was still writing the title?
