The Mercenaries in Team Fortress 2 all have very distinct silhouettes which allows the player to identify who is who. The characters also have very different personalities and its shown in the game.
Risk of Rain 2 also does a good job at having silhouettes. Also the shapes and animations of the character can tell you a lot about what the character specializes in.
Alex and Steve from Minecraft do the complete opposite at the other two games. It makes sense for a sandbox game to have pretty blank characters since it allows the make there own characters and personalities.
3 characters. I used shapes to make each of the three silhouettes very distinct. I imagine they would be some kind of magical fairy thing. i made them super simple.
