A new Sonic Rumble Party datamine appears to have revealed another batch of character skins before SEGA is ready to show them.
Images posted by DanTheDJ12 on Twitter show designs for Cream, Shadow, Metal Sonic, Blaze, Jet, Vector and Amy, including a full Halloween lineup and another board built around sports.
SEGA has not announced these skins yet, so their release is not confirmed.
The clearest of the new images is a Halloween-themed board featuring Cream dressed as a witch, Shadow in a black-and-purple outfit with a top hat and cape, and Metal Sonic in a dark hooded costume.
The three characters also appear to have matching Buddies alongside them, including a floating bat-like companion behind Cream and another small creature beside Shadow. A Dark Bat Buddy can also be seen in the artwork.
A separate board puts Blaze, Jet and Vector into sports outfits.
Jet is unmistakably dressed for hockey, complete with helmet, gloves and hockey stick. Vector wears a green-and-orange American football-style uniform carrying the number 95, while Blaze gets her own purple-and-orange basketball outfit and sneakers.
Another image shows Panda Amy, who along with Basketball Blaze, was teased earlier this month on the official Sonic Rumble Party social media accounts. The skin first debuted in SEGA Hardlight’s Sonic Dash and Sonic Forces Speed Battle, later appearing in Sonic Speed Simulator, and now it looks like this adorable fluff ball is making her way to Sonic Rumble Party very soon!
However, exactly how any of these skins would be released is still unknown. The images do not establish whether they belong to an event, Season Pass, shop rotation, Skin Fragment Challenge or another part of the game.
The Halloween designs have surfaced at a particularly interesting time, with Sonic Rumble Party Season 10 now underway through October 23. That would put Halloween comfortably inside the current season, although SEGA has not announced a 2026 Halloween event or tied these skins to Season 10.
Sonic Rumble Party has gone spooky before. Its 2025 Halloween event introduced costumes including Halloween Sonic, Mummy Knuckles and Witch Rouge, so another Halloween lineup this year would not be out of character for the game.
Datamines have also given players advance looks at Sonic Rumble Party additions before. Earlier this year, files pointed toward My Hero Academia and Angry Birds collaborations ahead of their official reveals.
For now, though, the images give us what looks like our first look at new costumes for Cream, Shadow, Metal Sonic, Blaze, Jet, Vector and Amy, with at least Halloween and sports themes represented among them.
