Well, it really depends on different fan preferences. Some might like a Connor who is a powerful fighter with unique semblance skills. For example, a Connor who can manipulate time in some way, like slowing it down during battles. This kind of characterization often makes for exciting action scenes in the RWBY fanfiction world.
It could be an older, more experienced android. One that has been through a lot and has a deep understanding of both the android world and human society.
Hank would be a very likely character. He already has a complex relationship with Connor in the original story. If Connor starts to become deviant, Hank's reaction could be very interesting. He might be suspicious at first, but then as he sees the positive changes in Connor, he could support him.
One common plotline is Connor joining the Beacon Academy. He has to go through the initiation process, just like Ruby and her friends. He might struggle with the physical tests or have an interesting interaction with Professor Ozpin during the interview. For example, Ozpin might sense something special about Connor that sets him apart from other students.
Well, it's hard to say for sure. The concept of 'porn-like' is quite subjective. Some might consider certain novels with excessive sexual descriptions as such, but it depends on individual perspectives and cultural standards.
In many places, 18+ porn comics are considered illegal. This is because they can have a negative impact on society and violate moral and legal standards.
