Allow me to share some!

Angel Island - Sonic the Hedgehog(associated with Knuckles)

The stage is mostly based of Sonic and Knuckles. In the background, the Master Emerald can be seen, lying atop a temple. Every 30 seconds(may be changed), the whole island suddenly is on fire, and fire can randomly appear on the stage, and parts of the stage can fall, and respawn shortly after. In another 30 seconds or so, Knuckles appears at the temple in the background with an angry look, and uses the Master Emerald to return the stage back to normal. If Knuckles is being used as a fighter, Metal Sonic appears instead, and has a small chance to actually steal the Master Emerald instead of returning the island back to normal, so that when the stage catches on fire, it'll stay like that for the rest of the round.

Snowdin - Undertale (associated with Papyrus'''

The stage is located in Snowdin, looking like how it appeared in Undertale. This part is in Snowdin Forest, and not Snowdin Town. A bunch of traps can occur, including being caught in a net for 10 seconds if they stand on an odd looking tile that can spawn frequently, spikes coming up of the ground randomly, and a fighter rarely being electrocuted if they stand on a random tile.

More coming soon, probably.
