The Sentinel Legacy

The original Sentinel was a massive mutant-hunting robot unveiled by scientist Bolivar Trask, who believed artificial enforcers were humanity's only hope against the perceived threat of mutantkind — setting the X-Men against one of their most enduring and iconic foes.

Alan Scott, the original Green Lantern, rechanneled his mystical Starheart-derived powers under the Sentinel identity. A founding member of the Justice Society of America, he wields green energy for flight, constructs, and force fields — with a unique vulnerability to wood rather than yellow.
