That's still a matter of authorial intent vs final outcome. Even then this becomes fuzzy as it contradicts earlier versions of the script. And even in the final product we know that Bombshell appears in later scenes in the movie and he appears in Season 3. Skywarp does not. But then again, the clone thing...

I'm NOT saying that it's definitively one or the other. This is truly a pointless discussion. Just take your pick and go with it. If you want to believe that Cyclonus used to be Bombshell then more power to you. If you want to believe that he used to be Salvo, then go for it. And if you want to believe that he used to be Skywarp, then go nuts with that too.
