Salvage Sonic "Storage-Up!" pose reference:

Also some Info!:

Fireceful Spicy Sonic: The First Skin ever I designed for Salvage Sonic since
the Prototype Comic, but the Skin never seen an outside light, until now...
(He has a Power of the Chili! Be careful, he's very Spicy!
Don't look at him for too long or otherwise your eyes will be flooded with tears!) (Obtainable from the Main Story Mode)

SAVAGE Sonic: The Second Skin, that was released as the first one.
The Skin looked completely different from the times of the Prototype Comic,
and it underwent a few small changes over time even with the second redesign.
(I guess this Skin is my favorite one).
In short, he has received a sudden "augmented with cybernetics".
Also the Clone is called in this form as "Fixed Sonic".
(Obtainable from the Main Story Mode)

Catharsis Sonic: The Third Skin...
Catharsis Sonic has appeared long time ago in the spoiler alert video.
Looks like that Salvage Sonic "Storage-Up!" has been recovered from his heavy
injuries and has a Power of "Hyper". What other Secrets does this Skin have?
That's to be teld in future...
(Obtainable from the "Secret Ending")
