Marvel Anthro head sketches (Patreon)

So if you guys saw the Lizard head sketches then this is just me practicing more head sketches, only with characters outside of the Lizard.

For the first character we have Iguana. In one of Curt's attempts to cure his wife, who is the Lizard, he creates and uses an enervator to help remove the Lizard condition in Martha Connors. Unfortunately when testing the machine it discharged and hit their pet Iguana (Iggy). This resulted in Martha's dna to transfer to Iggy as well as the Lizard formula, resulting in the creature to mutate into a humanoid form resembling the busty Lizard and had all of Martha's memories as well. However, her personality hated all humans and knowing she was basically a clone, did not care for Curt or Billy unlike with Martha. Afterwards Iguana acts as an assistant to the Lizard, helping with experiments on their bodies and making ways to keep the Lizard from becoming Martha or at least making sure the Lizard's personality becomes more prevalent. Despite not having humanity for others, she does care for the Lizard, her "sister" and tends to see Curt as a possible mate if he wasn't her "sister's." She sees Billy as a brat though.

Now Vincent Stegron was an assistant of Curt Connors on a project for S.H.I.E.L.D. that utilized dinosaur DNA from the Savage Land. He became obsessed with Martha Connors after seeing her as the Lizard. Taking the chance, he stole some dinosaur dna and offered the Lizard a way to escape if she followed him. She accepted and while also stealing technology from S.H.I.E.L.D. and some tech of the Jackal that was confiscated , the two made a device that would create "sexy dinos" according to Vincent. He used the Lizard as an experiment, wanting to see what would happen if he used her dna + dinosaur dna on himself. However, not knowing that the device made was a cloning machine, he was disappointed to see he didn't transform into a Dinosaur Man. Instead, a busty futanari clone of him came out and killed the original, deeming him a useless human. Stegron then got to work turning ever dinosaur on the Savage Land into anthros, the female dinosaurs became busty anthro woman while the male dinosaurs became futanari. Stegron would then have sex with the Lizard as a way to build her army of dinosaurs before attacking New York to make more people dinosaurs. Though it was thwarted by Spider-Man.

The last character is my version of Devil Dinosaur. Now for her, yes it's a rule 63 version I have a couple ideas on how it can go.

Devil Dinosaur is a futa due to Stegron turning all the dinosaurs of the Savage Land anthro. She and a r63 Moon Boy are of the modern age rather than from an alternate past.

Devil Dinosaur is from the past like the normal version and partners with Moon Boy or a r63 Moon Boy and travels to the future where Devil becomes anthro due to Stegron.

Devil Dinosaur is from the past but due to interference of aliens, several dinosaurs are transformed into anthros as experiments on life forms of the Savage Land. However several dinos escape the Savage Land and live throughout Earth before those dinos go extinct. Before then, Devil meets Moon Boy or a r63 Moon Boy, time travel ensues and they get sent to the future.

Let me know more ideas for how Devil Dinosaur can go if you want, I'm trying to not make it complicated by having another AU for Devil to come from when it's easier to have it be in the same AU as other characters, it's just that instead of dimension travel, it's time travel that may send Devil Dinosaur to the modern day.
