There's something
BaganSmashBros reminded me of when talking about signs of Ridley's intelligence but not sure if it's been brought up before.
Doesn't it seem odd that pyrosphere in Smash Bros. seems to take place after a battle, but in Other M it seems fairly intact
It could just be a sign that other people have been there before and came to their demise by Ridley, but to me it seems more like a nod back to the fight in Other M (with a few changes as all the pillars seem intact in Other M). Hence why it's damaged as it took place after the fight with Ridley, and explains some of the holes (anyone who played the game will know a certain iconic one).
So if Ridley was the boss in pyrosphere why would they base it on the area after the fight with Ridley that happened in Other M? It makes no sense to me, if I was making the boss I would have made it look the same as the pyrosphere before the boss fight in Other M (they could even add the bridge and it wouldn't impact anything), and make certain parts of it break when Ridley attacks, but all pictures so the exact same ruined pyrosphere.
