as far as Titania
I seriously doubt they'll use the Doctor Doom origin story
I'd be very very surprised if Doctor Doom shows up in She Hulk
but just by the actress they picked already changed her origin somewhat , as Mary MacPherran / Titania starts out as a runt that always got picked on before gaining her powers , well the actress they picked , Jameela Jamil is like 6 feet talk , hardly a runt , although I suppose they could do some CGI trickery
as far as Bruce Banner showing up in She Hulk , even though Dr Hulk was fun , for like 5 minutes , but lets get back to the Incredible Hulk , I mean come on , we all wanna see Hulk Smash !!!!!
Tim Roth returning as Abomination, I hope Marvel tweaks his appearance to a little more comic accurate
but that Hulk movie wasn't all that bad , that final fight between the Hulk and Abomination was pretty cool
been awhile since I watched that movie , might have to sit down and watch it again
again with Doctor Doom , he is going to show up at some , I suppose he could show up in She Hulk , but I'd be surprised , I just hope they don't pull a WandaVision / Mephisto tease
