Well I have only two weeks until I graduate high school and as such I doing some more planning for The Inferior Spider-Man fanfic. So far I create the roles of the main characters and here they are:
Note:This is early stages and as such suggestions are openly welcomed.

1. Superior Spider-Man/Otto Octavius: Will be the main villain as he feels that even though he just wiped his new brain all the remnants of Peter Parker, his "stain" is still in the world and won't make him truly superior in his eyes and as such feels that he must "erase all factors of Parker". Meaning he must eliminate all of Peter's greatest allies and worst enemies. However, his actions is causing time itself to decay and will wipe out the universe itself in only a few weeks, starting with earth. But due to his arrogance, Otto ignores this and decides that his goals will justify the means.

2. Miguel O'Hara/Spider-Man 2099: The main protagonist as he notices the damage Otto is doing to the universe and it has already taken affect in his own time period. Desperate, he uses an Alchemax time machine to travel back to modern New York City to correct the problem by stopping Octavius at all costs. So he'll resort to his intelligence and gadgets to go up against Otto while proving to the Avengers, Agent Venom, and Peter's love ones that the Spidey they know isn't who he is.

3. Agent Venom: After defeating Toxin and the Symbiote Slayers, Flash was approached by Captain America to track and confront Spider-Man as he has being far more ruthless and violated his previous "parole". However, when he meets his hero, his Symbiote senses that Spider-Man is different and Flash realizes that Spidey is not truly friendly.

4. Scarlet Spider/Kaine Parker: Hesitant at first, Kaine decides to return to New York to face his cousin as he saw on the news just how violent this new Spider-Man is. But once he returns, he becomes the instant target for Octavius as Otto sees Kaine as the biggest threat to his disguise and that a clone is far inferior to him.

5. Mary Jane Watson: Though she tried to disbelieve just how different "Peter" was becoming until he becomes his first target. She also tries to reason to the other Spider-Men that they shouldn't try to jump to conclusions that this isn't Peter Parker. That is until she confronts Spider-Man and finds out a horrifying truth...

So those are they main characters, but not the only ones. As I said they aren't the only ones and here's a list of either side, minor, or cameo characters I have planned (and suggestions are opened):
