I realized I forgot to go into these guys, so here:
Sonic: The blue blur himself! Leader of the squad and hero of Seaside Island. At least, he's seen as a hero by the village, Sonic himself doesn't care about being the hero. He just wants adventure and to keep those he treasures safe! That being said, his friends have disclosed that he can sometimes be a little full of himself and can be hard to read when he's upset.
Tails: Amelia Prower, or Tails, is smart in terms of her intelligence and tongue. She has several world records for several types of rubix cubes, prowess in mechanical engineering, and can be seen sassing Sonic daily. Despite that, the two are inseparable and have been since childhood. It's rumored, though, that behind those smarts and snark is an anxious and insecure girl.
Knuckles: One look at this guy, and you know not to mess with him. Knuckles hails from a warrior echidna tribe and shows that on his sleeves. He's quite tough, but don't let that intimidate you, Knuckles is the definition of a gentle giant. He may not be the brightest, but he makes up for that with a ton of heart!
Amy: Every friend group has the "mom," and Amy is this one's. Loves her friends dearly, especially Sonic, and will smash someone to bits if they threaten them. She has plenty of love (and strength) to spare. Amy has stated that she will be by Sonic's side till her very end, how sweet!
Sticks: The newest and wildest member- literally, they found her in the wild. Sticks is a huntress and avid scavenger, as shown through their makeshift clothing. He hasn't known the gang too long, but is very dedicated to them. With their trusty stick in hand, she'll tear through any danger! (Also, they use all pronouns. Gender means nothing to Sticks.)
