Fictional character biographyEdit

The Tri-Sentinel's first appearance was in The Amazing Spider-Man #329, which followed on directly from the "Acts of Vengeance" storyline. In that storyline, several superheroes including Spider-Man, Captain America, Thor, Iron Man, and Cloak and Dagger came together to fight the Asgardian trickster god Loki. After Loki's defeat at the hands of Thor, Loki engaged in a final act of vengeance by creating the Tri-Sentinel by merging three Sentinels that belonged to Sebastian Shaw. The Tri-Sentinel was sent by Loki to attack a nuclear power plant and thereby destroy New York City. It was defeated by Spider-Man, who at that time possessed the powers of the Captain Universe entity.[1]

In a subsequent Spider-Man storyline, the villainous Life Foundation gathered the remains of the Tri-Sentinel and rebuilt it to serve them and provide security for their clients. When Carlton Drake turned it on, it rejected the Life Foundation's directives and reinstated Loki's. Spider-Man and Nova undertook to defeat the Tri-Sentinel.[2] Nova used an aircraft-mounted magnetic cannon to slow it down, while Spider-Man penetrated to the inside of the Tri-Sentinel's armour, fought its automated internal defence systems, and opened a vibranium container at the Tri-Sentinel's core, causing the Tri-Sentinel to melt before reaching a heavily populated area.[3]

The Hellfire Brats later began producing their own line of Tri-Sentinels, advertised with the pitch, "The Mark VIII. Our take on the Tri-Sentinel. A walking slaughterhouse, powered by its own miniature nuclear reactor. When nothing less than genocide will do."[4]

The Tri-Sentinel resurfaced where it attacked New York City. It faced an Isotope Genome Accelerator duplicate of Spider-Man. Because the duplicate doesn't have Peter Parker's responsibility, he drove the Tri-Sentinel recklessly through the city upon hijacking it.[5] Mendel Stromm was revealed to have obtained the Tri-Sentinel from the bunker of the bankrupted Life Foundation. After that Tri-Sentinel was destroyed and he broke down in tears, Stromm was approached by a mysterious benefactor who provided him a Master Mold that specializes in creating Tri-Sentinels.[6] After Spider-Man and Peter Parker were brought back together, Spider-Man was able to take remote control of the Tri-Sentinels and send them back to the Master Mold base to destroy it.[7]

Powers and abilitiesEdit

Tri-Sentinel's strength level is at Class 100 and it can fly. It can shoot bolts from its eyes, shoot tear gas from its hands, create energy fields to protect its interior and exterior, fire tentacles from its palms, and regenerate. Tri-Sentinel can override technological backup self-destruct devices. In the event that someone goes inside the Tri-Sentinel, it can use its internal components as projectiles.
