Origin Sonic's "Midday-Up!" Skin from Fierce Forces:

Unlocked after beating the main story mode of "Imagine It!" comic in Good Ending, called: True Vision.

In this form, Origin is an ally of Silent and this time, he cannot be controlled either by: Shadow Sonic "Midnight-Up!" / Dr. Golden "Prepare-Up!"
(also he changes the side to the Good faction: Valorous Resistance, instead of being in the Evil faction: Nefarious Empire.)

He's summoned as a Comrade Companion from Silent's White-Gray Concord Gem/Bracelet (called to the fray just as the Security Guards are.)

Hyperspeed! Origin Sonic is faster than speed of light and even than Sonic The Hedgehog.
