I believe the whole
Disney multiverse itself is pretty much possibly one of the biggest and ultimate examples of all time here.
Despite existing longer than both Marvel and Dc as a media corporation with a history spanning a whole century's worth of so many multiple different franchises, series, and works ever put into production with countless characters ever conceived from them by extension...
Most of Disney's iconic and popular characters by and large seem to range from being just
human/street/wall-level to anywhere
short of planet-level (or even maybe
city block-level) at best.
Outside of the Genies from Aladdin and your obvious toonforcers like Mickey, Donald, Goofy, and other classic Disney toons from the Golden Age of Animation at least.
However if you broaden the aperture of Disney media to include everything like original animated tv series and comics rather than just limiting them to just your theatrical movies or classic animated shorts, then at the top, you have dudes who are literal higher-dimensional cosmic entities like Bill Cipher and The Aoxotl from Gravity Falls as well as other crazy reality warpers and magical gods like Star Butterfly and Glossaryck from Star vs The Forces of Evil whom operate on a multiversal or even megaversal scale (if Volt Manta from OBD was correct). And from what I heard, the comics also give Mickey and Donald some rather insane feats of their own.
And even within just the Disney Animated Canon (and their animated spin-offs), you still have several other heavy-hitters apart from the Genies and Chaos from Aladdin who are gods and reality warpers or very haxed characters: Yen Sid, Chernabog, Zeus, Merlin, Fairy Godmother, Blue Fairy, some abstract beings from Fantasia, Alice or Cheshire Cat from Alice in Wonderland, Holio (Experiment 606) from Stitch, and Wish.
With just the strongest characters on top, it's safe to say that Disney is easily one of the biggest and most powerful verses of all time (without even including Marvel itself). But mostly everything below them would probably lose to anime-verses like DBZ or even the HST sadly (or not).
That is all.
