This is truly the Sonic we know of.

This is what Sonic12 usually look like without any disfigurement to its physical form. This is what happens when it ran it's errands, or became so bored that it just disconnects it's mind for a bit.

In this state, it's at most the least threatening Sonic12 is. It acts lifeless due to it mimicking the accuracy of the mainline Sonic games. If any other expression were made or doesn't match with the right one in a sprite, then this means it's ready to play again. It doesn't use this design to trick anybody, gain their trust, or force somebody to believe that it is Sonic. It uses the design in any casual standards, either being true to its character, or do what it usually does in-game.
