Trans super-per-day #520: Marvilla! Created by Thomas Heaven, Marvilla is an adaptation of the M.F. Enterprises version of Captain Marvel, now originally with the code name of M.A.R.V.E.L. He is destroyed with only his left hand surviving, with said hand being found by a little girl, who teaches it sign language and treats it as her friend, and when she grows older, gives it manicures and jewelry. When the woman dies in 2010, the hand goes back to its creator and helps in building a new body for it, this time a gynoid rather than an android.
As an adaptation, the character is a synthoid who has the ability to detach their body parts, each part still being controlled by the whole. The original version would shout "Split" to split body parts off and "Xam" to re-combine, though it's unclear if this is true for Marvilla.
