My mind is currently split right now between 2 stories I'm interested in writing:
A) a Kryptonian/Viltrumite hybrid sent to assist Omni-Man on his mission to conquer Earth but he falls in love and ends up caring about the planet, similar to the Doctor, and defects from the Viltrum Empire to join its defence.
B) The first Hydra/Red Room Mutant spy who is sent to infiltrate the Avengers as a fake hero, in order to destroy SHIELD from the inside. However along the way he starts to enjoy saving people and must convince the other mutant spies to abandon Hydra and become real heroes.
What would you guys prefer????
