SAWTOOTH

Sentinel Fireteam Alpha were cybernetically bonded with Sentinel tech and nanobots. Because the "Destroy All Mutants" protocols were so deeply enmeshed in Sentinel programming, Larry Trask found a way to avoid overriding Fireteam's independent thought with these protocols by harvesting nanotech from Juston Seyfert's inexplicably reprogrammed Sentinel. Unfortunately, this too seeped into their brains before too long, through a degredation known as "grafting".

The Sentinel Firearm were advertised as survivors of various Marvel crossovers. Sawtooth was a S.H.I.E.L.D. agent who resigned rather than serve Hydra during Secret Empire.
