Character Cards

Character Cards were one-time collectable items found in specific worlds, that when collected would unlock a specific character. There were 4 character cards featured in the game, them being Sonic's card, Tails' card, Knuckles' card, and Invisible Espio's card. Sonic's card was situated in Green Hill, Tails' in Lost Valley, Knuckles' in Emerald Hill, and Invisible Espio's in the Synth City Obby; no other worlds contained a card. Getting a card would serve as both a minor test of the player's skill and a test of their level, with each card having some sort of basic challenge involved before the player could reach it. 
Character Cards were introduced to the game before v1.0, and they would remain in the game up until the v2.0 Sonic Shock update, where they were removed. 
== Trivia == 
*In total, there were 4 worlds that contained character cards, and 9 that did not.
*The v1.2 Scavenger Hunt Event featured collectables called Character Fragments, which were very visually similar to character cards.
*The v1.38 Snowboard Slopes Event featured collectables called Autographed Stickers, which were very visually similar to character cards.
* Aside from potentially the Sonic card in Green Hill, none of the card locations seem to have any relation to the characters they unlock.
*The Character Card for Invisible Espio was completely invisible, which made it hard to find without the use of external resources.
*After v1.1, character cards went unused all the way until v1.35 with the addition of Invisible Espio.
