Sonic Forces is the best OC creator. If I had to compare it to something, it's like Picrew or Gacha except it's Sonic. The different customization options include "Upper Headgear", which is something your OC, who I'll be referring to as "The Rookie" from now on, can put on his/her head, "Middle Headgear", which is something the Rookie can put on his;/her mouth or cheeks, "Lower Headgear", which is something the Rookie can put on his/her chin, "Shoes", which are... well... shoes, and "Gloves", which are... well... gloves. In addition, we have "Wispon" which is the weapon the Rookie uses in the game, and "Fur Color" which is... exactly what it sounds like.
