Sentinels

Nimrod - repaint of the X-Force figure into more classic colors, not quite on-model but could have been a logical repaint by Toybiz.
Sentinel - the Marvel Legends Series 10 BAF (build-a-figure), very reminiscent of artist Marc Silvestri's art
Master Mold - from the X-Men Super Shooters series, he has Sentinel shaped projectiles that shoot from his mouth!
Classic Sentinel - this 2006 14" Toybiz X-Men Sentinel was a redeco of the previous X-Men animated series release, with a better paint job and a new head sculpt. Kinda simplistic compared to the Legends BAF version but a good representation of a classic model of Sentinels.
Bastion - repaint of the Archangel body with Cable head.
