The roster: nineteen playable characters
The launch press release names the cast one by one. That list is far longer than the four characters the store art shows.
Nineteen playable characters per the launch press release: sixteen Sonic-series fighters, Super Sonic added on release day, plus PICO CAT and Sonic Pico Cat. Every one can Spin Dash. No character stats are published anywhere.
The store page shows a handful of characters and lets you assume that is the roster. The launch press release names them one at a time, and the list is much longer.
Seventeen Sonic-series characters including Super Sonic, plus PICO CAT and Sonic Pico Cat from the PICO PARK side. Nineteen playable in total, and every one of them can Spin Dash.
All nineteen, from the press release
The names below come from the PICO PARK Inc. launch press release, republished by Famitsu on release day. This is the only official enumeration of the cast that has been published.

| 2 | Tails | Sonic series |
| 3 | Knuckles | Sonic series |
| 4 | Amy | Sonic series |
| 5 | Shadow | Sonic series |
| 6 | Cream & Cheese | Sonic series |
| 7 | Silver | Sonic series |
| 8 | Blaze | Sonic series |
| 9 | Big | Sonic series |
| 10 | Rouge | Sonic series |
| 11 | Espio | Sonic series |
| 12 | Charmy | Sonic series |
| 13 | Omega | Sonic series |
| 14 | Vector | Sonic series |
| 15 | Metal Sonic | Sonic series |
| 16 | Dr. Eggman | Sonic series |
| 17 | Super Sonic | Sonic series, added at launch |
| 18 | PICO CAT | PICO PARK series |
| 19 | Sonic Pico Cat | PICO PARK series, PICO CAT in a Sonic costume |
The press release lists sixteen characters as previously revealed, then announces Super Sonic as a new addition on release day. PICO CAT and Sonic Pico Cat are described separately as the PICO PARK series' representative characters.
Super Sonic and Shadow
Super Sonic was revealed during the fourth episode of the official PICO MART programme, on November 12. Per the same release-day coverage, Sonic can transform into Super Sonic in certain stages. That is the whole of the published description: certain stages, not all of them, and no stated condition for the transformation.
Shadow has an ability of his own. By collecting a Chaos Emerald in certain stages he can activate Chaos Control, which freezes time to help teammates get past obstacles. Also revealed during the PICO MART broadcast, also described only in those terms.
Those two are the only characters with a named individual ability in any official material. The rest share Spin Dash and whatever the stage gives them.
PICO CAT, and the cat design
PICO CAT is the PICO PARK series mascot, and the official portal describes the design in one memorable line: they were not meant to be cats, but everyone thought they were, so the name stuck.
The block cats are literal rectangles. Two square black eyes, small triangular ears, no limbs to speak of. In the store stills they appear in four colours: a light blue, a pink, a yellow and a pale green. Sonic Pico Cat is the same body in a Sonic costume, which is the crossover's own joke about itself.
No character has published stats
No character has a published stat line. No speed, no jump height, no Spin Dash charge time, no weight class. The store does not list them, the official site does not list them, and the achievements do not reference them.
That gap matters because roster pages on other sites will fill it. If you see a table of Sonic's top speed or Knuckles' jump arc on a guide for this game, ask where the number came from. There is no official source for it.
Picking one with no stats to compare
With no stats to compare, character choice comes down to two things: which body you can see in a crowded eight-player screen, and whether you want a character with a named ability.
Super Sonic and Shadow are the only two with individual abilities described anywhere. If a stage is walling your group, trying one of those two is a reasonable first experiment, because their abilities are the only ones the game has publicly said exist.
For everything else, the block cats are the easiest to track on a busy screen because they are simple shapes in four distinct colours. That is not an official advantage. It is what happens when eight characters stand on the same blue block.

Spin Dash covers the one move every character shares, and why its most-unlocked achievement is about hitting your own team. How to play explains the goal plate rule that makes the roster size matter. And the six screenshots page describes exactly which characters appear in each official still, if you want to see the roster in situ rather than as a list.
