At any rate
Doctor Moon created

Yeah, it's "not" the Jackal, but a similar character. Oh... it's been over 20 years since I saw it... I just read on the wiki something I'd forgotten, or maybe never saw that episode.... Dr. Moon made a decoy clone of himself... and it was the DECOY who cloned Spider-Man. Hunh, ok, that's a weird twist, I only hazily remembered. Not only did these clones have accelerated aging, but somehow were born evil. Also... I may have been wrong. they might have been born with the memories of the original.... but an evil personality. Not sure who came up with the mind control devices though. Or were those used to copy memories? Hard to remember, it's been so long....
Oh yeah, that reminds me... Nicholas Hammond, great Spider-Man!
But he played the role almost 45 years ago.
Yeah, the memory copying thing needs explained. I THINK Dr. Moon used a device that copied memories in real time when it did the transfer, so it was fresh and not an old copy. Hard to be 100% sure when the copies are always evil though. I vaguely recall a scene where the original9probably) Dr. moon waxed philosophical about not understanding why his cloning process didn't work right. A: evil, B: they deteriorated and died shortly after being made. The Dr. Moon and Spider-Man clones both died quite soon. I think Moon tested his procedure by cloning rabbits... which also died... somehow aging SLOWER than Humans created this way. I think the rabbits were also evil, but since they're rabbits it's hard to notice.
