Sonic and Crew High School Adventures is the series based off the lives of teens the age of sixteen (except one who's age seventeen). The main characters are Sonic, Tails, Knuckles, Cosmo, Gary, Sliver, Shadow and Espio.

Sonic T. Hedgehog

He is one of the main characters and is the teams leader by default. He has super speed but is very dumb his dessing is close to Ben Tennyson's, mostly in jacket dessing. He is proven to be able to swim but is too lazy to ever swim. He also has a rival who's power is the opposite of him and also rivals aganist Jet and many others. A running gag is sonic is always sarcastically saying they are not even supposed to be doing something or saying he learned something that day.

He owns extreme gear as his only form of transportation.

Miles "Tails" Prower

He is the weirdest character of the show after suffering a horrible accident. He went mentally insane to believing hes a wild wolf/dog as he is always walking on all fours but in later seasons he has shown more human behavor like walking and speech. He is also the richest kid in the world but has shown no hints of spoiling himself from his childhood. He is shown to like music as he has headphones on in the episode "Invasion of the Homeless". He has a large crush on Cosmo as to the point to licking her ear.

Knukcles T. Echidna

He is the dumbest character on the show as he does everything unknowingly, but he is possibly smart. He is the strongest part of the group and is commonly seen near Sonic as he always listens to him.

Gary "Smart" Prower

He is Tails' older brother and the only seventeen year old in the gang. He has the ablity to read minds. He seems to be more mature as he never listens to Sonic. He always speaks for Tails, but claims he can't read Tails' mind (he claims all he hears is static in Tails' mind) he is the only one who knows how to drive.

Cosmo T. Seedrian

She is the only female in the group and the love interest of Tails. Her home is never shown but refered to a lot. She always wears the same clothes though wears very few different outfits. Tails is possibly the most close to Cosmo as it is revealed Cosmo sleeps in Tails' room with Tails sleeping at the foot of his bed like a pet dog would do, which the reason is unknown. Tails possible cause Tails like a normal pet dog is lonely and also probably cause Gary wants Cosmo to take care of Tails room.

Sliver T. Hedgehog

He is one of the main characeters and he is some times mistaken for a girl or acts like a girl (possibly cause sliver is normally a favorite color of a girl). Unlike his other apprences his spikes are lower giving him a different look. He has the same powers he has in the game.

Shadow T. Hedgehog

One of the main characters and also a anti-hero. He has chaos powers and commonly hates Cosmo. He is seen near Espio all the time but doesnt speak much. He is a expert of guns as shown in the movie as he is the leader temporarily and a sniper in the movie.

Espio T. Chameleon

He is a ninja and also always invisible, he seems to be second in command in the movie.
