Ratchet should take this by a landslide to be honest. I can't be too sure about the order of deaths, but Sly is probably the weakest of the bunch.
Sackboy Becasue He Tanked Planet Size Explosion Twice.
Could've sworn Spyro was Large Planet level or something. Ratchet reaches plamet at best if we give him the benefit of the doubt. It was a fairly small star, putting shame to Galaxy's small cosmic objects. It DID generate planet level blasts though. IMO, Spyro should take it due to Ratchet's power being more debatable plus time manipulation gives hime even quicker reaction times, right? So he'd also have a slight speed advantage.
But that's me
Crash takes this if we scale him to N. Tropy who is stated to have the power of Space and Time and creates Time Paradoxes just for fun.
Ratchet can win this battle if he use the weapon that can turn characters into sheep.
That doesn't inherently make him universe level. And even if it was, it was never stated Crash could do the same. Crash only beat the dude; he can't use his hax.
