Assist

Assist is a move that appears exclusively in Sonic Colors' multiplayer mode, the Sonic Simulator. It allows one player to stand by while the other traverses the level on his/her own.

Description
When a player presses the 2/Y button in 2 player mode in the Sonic Simulator, the Virtual Hedgehog/Miicontrolled by that player turns into an orb. This hovering orb follows the other player, who can now continue alone. Although the player is powerless to control the orb, his/her Virtual Hedgehog or Mii is invulnerable. At any time during the level, the player can revert into Virtual Hedgehog.
