Repurposed Metal Sonic, hmm... could definitely be interesting having basically a rogue agent out there. No loyalty to anyone but himself, but still seeking to beat Sonic. Definitely has potential for sure!

Not gonna lie, Metal Sonic as an alternate gameplay mode would had been fascinating in Forces.  Heh, they wouldn't even had needed to write lines for him!

Metal Sonic has shown that he is capable of betraying Robotnik.  Whether it was real or fake in Heroes is up for interpretation but the idea that even his greatest creation could turn on him is a fascinating one.

Giving Metal Sonic the impetus for betrayal by a third party makes sense given how many different versions of Sonic-styled Sonic Killer robots there are and how many distinct iterations probably exist in the comics to boot.  There's bound to be at least one that wasn't recovered by Robotnik's forces (or even Sonic and co considering Gemerl).
[quote]As for Talos, I do actually have plans later down the line to introduce Shade and possibly some others from the Twilight Cage through some dimensional distortion stuff. So we could wait till then, or he could literally be the first foot soldier sent to Mobius, perhaps as a test of their device they used to send him there. If I recall correctly, it allowed them to temporarily exist outside the cage. Maybe it malfunctioned and trapped him there? Plenty of room to play.[/quote]
I was toying with the idea of a bunch of initial tests sending weak or expendable low ranking troops as "Marauders".  Aside from the armor looking the same, it'd be easy to claim they were rouge agents if something went wrong.

How many "failures" there were is up in the air.  Especially since I'm not entirely sure how the temporary dimensional shift would handle if the person is killed or turned into a Robian.  In this case, Talos is just letting people assume he's a cybernetic or powerarmor-wearing Snake.
