Honestly, I prefer the cloning method.
Teela as a naturally hatched daughter just bugs me on multiple levels.
1) The whole 'zoar' issue is a big one. Even as a kid I realized the baby in a nest presented serious problems...
2) Sorceress is supposed to be some all powerful, mysterious guardian of grayskull. The idea of her 'hooking up' is just... bad.
3) Since when did 'Sorceress' become a title that passes down mother to daughter? Tella'na wasn't related tot he one before her. If MYP wanted to say there was a bloodline going all the way back to veena... then Adam and Teela share the same bloodline.... Gets a bit too 'Skywalker-ish' there...
Fans of Superman II and even Superman returns can point out that 'magically erasing your lover's memory after your done with them... is NOT COOL...
MYP had gave her a 'husband'... but then pointed out he had no memory... and she never got his name
If it's MAA... She wipes his memory of their 'good times'.... if it's FIsto... He ditches her the moment he remembers his name...
There are WAYYYYYYYY too many hoops to jump through to make 'natural born' the least bit palatable..
Magic spell gone awry? I remember the old days when Skeletor wanted to 'marry' Teela... Now he's hooked up with Evil Lynn and has a kid.... With all the focus on 'bloodline' in MOTUC, I could see some kind of prophecy that Skeletor NEEDED a powerful Sorceress for his mate and their progeny would be the key to his power or something...
The more the bios continue... the more it seems like EL was a contingency plan.
Also, looking at how often Sorceress gets weak and passes out in filmation... or succumbs to poison... or basically NEEDS Adam as much as she does... the idea that she's 'half-power' fits in REALLY well...
