Games
This game was the first game in which Sonic was playable, and started the franchise as we know it today.
Sonic The Hedgehog!!
This Sonic character has been in every game since Sonic 2 on the Sega Genesis back in 1992.
Miles 'Tails' Prower!!
This form is the first different form we have seen Sonic in, which he is able to transform into by getting all of the Chaos Emeralds, and requires 50 rings to transform.
Super Sonic!!
The main villain that everyone knows and loves (and or hates), ever since the first game back in 1991
Doctor Ivo "Eggman" Robotnik!!
The first television show Sonic the Hedgehog ever starred in
The Adventures Of Sonic The Hedgehog!!
This game introduced Sonic's sidekick and is one of, if not the best Sonic game to date.
Sonic The Hedgehog 2!!
This Sonic character was in one major game as a main character and was never in a standalone game, appearing as a background character/side character ever since that game.
Silver The Hedgehog!!
This form is technically not canon, tho it did appear in one game (Sonic 3 & Knuckles) And never appeared in a game since
Hyper Sonic!!
The robot version of a certain character that was made to destroy Sonic, but overall failed, but has still been in every game since his first appearance.
Metal Sonic!!
The first show to give Modern Sonic a different look, which the internet has grown to hate because of this said design, this show also made the second worst sonic game ever made..
Sonic Boom!!
This game was the first game to introduce "Modern Sonic" as they call him, and changed his design, now being the new Sonic we all know and love today. This also brought Sonic a voice actor, who they have changed multiple times since this game.
Sonic Adventure!!
This Sonic character had his own game TWICE (Three if you count 06) and has been in every Sonic game since. Also, he's kinda like Sonic's rival, I say kinda because they seem like friends half the time.
Shadow The Hedgehog!!
This form was made by Eggman trapping Sonic and using a laser powered by Dark Gaia to blast the Chaos Emeralds out of Sonic, and when the sun is down, Sonic turns into this form
Wearhog Sonic!!
Infinite!!
The first "anime-style" television show that Sonic was in, as well as the first appearance of Dark Sonic.
Sonic X!!
This game was the first full-length Sonic arcade game, having three playable characters, and the control was a trackball.
Sega Sonic The Hedgehog!!
This Sonic character appeared in one game and was never seen again, tho was a major character of that game.
Princess Elise the Third!!
This form was shown once, in a TV show, and fans loved it, hell, maybe you already know this one-time form. How he transforms into this form is by getting really angry, im sure you already know it by that hint alone
Dark Sonic!!
An alternate universe version of Eggman, which, if you say his name wrong... You might get in trouble
Eggman Nega!!
The first movie to make Sonic's design worse, then come back and make it 100 times better.
Sonic The Hedgehog (2020)!!
This game was the first time Sonic was ever seen, tho he was not playable, he was definitely seen.
Rad Mobile!!
This Sonic character appeared in one major game, as an NPC, and was never really mentioned or seen since that game.
Sonic Man!!
This form is transformed into via rage, sadness, and hatred, giving him an indigo-type coloration. This form is powerful, but I wouldn't say it's his most powerful form.
Darkspine Sonic!!
A villain that has only appeared once, but looks exactly like a certain character that has black as their main color, and he has no mouth
Mephiles The Dark!!
The first full-length film Sonic was ever in, and no, it's not Sonic The Hedgehog (2020)
Sonic The Hedgehog: The Movie (aka Sonic OVA)!!
