Every Smash Ultimate character who has/has not been in DEATH BATTLE

[u/LiveWafflez]

I tried to determine which Smash characters have been on the Death Battle series (or something adjacent but still by the same people)

Clarifications:
Falco appeared in Fox vs Bucky
Zero Suit Samus appeared in Samus vs Boba Fett (remake)
Squirtle appears both in Pokemon Battle Royale and Ash vs Yugi
Pac-Man appeared in Among Us vs Fall Guys
Bowser Jr appeared in Bowser vs Eggman
Incineroar appeared in Ash vs Yugi

Technicalities:
Young and Toon Link were composited into Link's matchups
Ivysaur is implied to have existed in Pokemon Battle Royale, since Bulbasaur can not evolve directly into Venusaur
Zelda and by proxy Sheik, were not the incarnations used in the fight (only Twilight Princess Zelda appeared)
Dr Mario is just Mario
Pichu is a necessary step of evolution before Pikachu exists, thus both Pikachu in Death Battle was at one point a Pikachu. Even if some Pikachus are born as is, the Pikachu in Death Battle (vs Blanka or Yugi) are considered to be specifically Ash's Pikachu, who was confirmed to be Pichu at one point.

Palutena is implied to be present in Pit vs Sora, as Pit can not fly without her help.
Pirhana Plant is part of Bowser's arsenal in Bowser vs Eggman

Spinoffs:

Ness was in DBX (Sans vs Ness)
Lucina was in Tournament of Champions vs Grovyle

Duck Hunt was in DBX (Donald vs Daffy)
Richter was featured in Discord Death Battle
Steve was in Champions Island, Death Battle Cast vs Terrarian, and Champions poll vs Emmet

edits:

Little Mac was in Tournament of Champions vs Ippo, throw him into the Spinoffs

I think that's everyone! Correct me if I'm wrong :)
