Brotherly rhapsody au 2012 version
Do you think that branch meet slash when he was a little turtle or when he's already mutated?
Well, since you brought it up, I was actually thinking that Ramón's presence might affect Slash's existence.
As I mentioned in the first questions of this version, Ramón mutates and is found by April and the turtles practically a month later. Since I personally prefer watching the seasons progress by year instead of a strange, rushed two-year period that compartmentalizes the first four seasons, there would be a longer time between each episode than usual. I don't remember exactly when Spike's mutation occurred, but Ramón would appear before that happened and would only know Slash as Raph's pet turtle.
And as I've also been mentioning, Ramón's presence (and consequently Brozone's and perhaps other characters') could radically change certain events, relationships, and character development.
In Slash's case, since Ramón would have appeared before the Slash and Destroy episode, he would have known Spike as Raph's pet, and that would have helped Ramón and Raph get along. Even though Shelliot died in this universe, he was very important to Ramón, and he would quickly remember him upon seeing Spike. Raph feels sympathy for the boy and his briefly deceased pet, so he would teach him how to care for Spike and let the boy play with him. Also, to build trust, he might ask Ramón to do him the favor of watching Spike when Raph isn't around, and Ramón would be very diligent in this task.
Then, by the time the Slash episode aired, the same accident in which Spike was almost hurt could have occurred. However, it wasn't just Raph who was angry about it and complained to Splinter, but Ramón as well. Even though he barely knows them, he also tells Donnie he needs to be more careful with his things, and goes with Raph to his room. There, he makes sure Spike is okay, and Raph isn't so upset knowing that, at least for that one time, he has someone with him.
However, Mikey comes to ask Raph for help cleaning, so he reluctantly goes. And since Ramon is there, Raph asks him to look after Spike and keep an eye on the mutagen bottle.
And well, it's thanks to Ramon's presence that the mutagen doesn't spill and Spike doesn't get near it and mutate, thus ensuring that Slash never exists in this universe and remains just Raph's pet for much longer. In the end, since Spike didn't mutate, the conflict between Raph and the others is eventually resolved with Ramon's help, and well, everything ends quite well.
So, I'm afraid there's no Slash in this AU. Sorry to the fans. :V But you know, I'm literally introducing new characters to this universe, so it makes sense that changes like this, and many others, happen. Oh well, what can you do? ¯\_(ツ)_/¯
Thanks for asking!
