I mostly plan on a few guest characters somewhere in the future.

Currently I have 2 Bomberman and Mario

I dont mind which should be choses for a first guest character. Heres a few sprites i plan to use for Bomberman.

Mario's just gonna be quite obvious.

Continue. But classic

2/3 of them are references to

Sonic's Concept and is also a Skin in Sonic Superstars Cream's Debut (Though inconsistent looks)

A former 90s rival's (A red capped plumber guy) recent 3D platformer since 2017

Early previews of "Shining Wine (Not alcohol)" and "Castle Party"

A returning move from Infinite Battle

but a bit more on Sonic 06's Green Gem.

(Not finalized yet but its a resemblance.) I have decided to make it 3 Buttoned. Though the Basic attacks mapped A,B and C buttons will also be mapped to X,Y and Z

The Classic Hop and Dive. (Amy Rose)

That Hover Move.

It's like the OG game but less stiff.

Yoshi and Birdo cosplaying as Ichigo Momomiya

Act Music as Rounds? (may not apply to every stage)
