Notes:

• Sonic! AKA Mr. Needlemouse – Obviously based on Mickey Mouse in design
• Tails! – Mickey Mouse shorts
• Knuckles! – Fightin' stovepipe hat hobo!
• Amy Rose, Cream the Rabbit, and Cheese the Chao! – Flapper Girl, Oswald ears
• Uncle Chuck! – Dapper fellow with a cane and a bowler hat
• Princess Sally! – She's happy now that she's be Unclockworkicized! Compare her pose with Nicole's
• Antoine & Bunnie! – Happily married couple, Bunnie has square Oswald ears to differentiate her from Cream and Vanilla
• Boomer! – Chubby newsie type walrus mechanic
• Nicole the Clockwork-Lynx! – She's a wind-up girl
• King Acorn – He's written in Tim Curry's old voice now. I based his design off King Blozo from Popeye/Thimble Theater
• Vanilla the Rabbit – Classy rabbit lady. Doesn't she look motherly? The carrot on her umbrella even has eyes
• Shadow AKA Mr. Grumpymouse! – His precious Maria was tied to a railroad track so now he threatens to close down the orphanage!
• Rouge! – Sultry Femme Fatale Bat lady!
• E-123 Omega! – That's one angry trashcan!
• Vector! – He's in his old design, but instead of listening to music, he's just really, really cold.
• Espio and Charmy! – Did they even have Ninja's in black/white cartoons? Espio's too stoic for artistic interpretation (also, "Japanese" tropes from that era are really racist lol) and Charmy's an annoyance no matter what the time period.
• Mighty and Ray! – Obviously based on Popeye. Ray is his precocious second in command!
• Blaze and Marine! – The polar opposite of Amy and Cream. Blaze is a conservative flapper girl, while Marine is a rough and tumble lady pirate!
• Silver! – This poindexter is always trying to bend spoons with his mind.
• Bean, Bark, and Nack – This gang of Hooligans are nothing but troublemakers! (Also, Bean is wall-eyed AND pie-eyed.)
• Thrash! – Fightin' stovepipe hat hobo
• Professor Eggman and his sidekick, Snivvles – Based off of Pajama Eggman of course.
• Naugus the Goblin King – Devilish little claw-handed imp!
