Bastion

Bastion is a Super-Sentinel, an amalgam of Master Mold, and Nimrod. The fusion happened when Nimrod encountered a module from Master Mold’s body. After being forced into the Siege Perilous, The heterogeneous symbiotic being who would become Bastion was created, with no memory of his history. Bastion was able to live among humans and became aware of the mutant presence, which unbeknown to him, re-activated his mutant-termination directives. Bastion somehow managed to infiltrate the American Government and gain access to Project: Wideawake, a governmental commission created to analyze and manage the "mutant menace", and its mutant neutralizing technologies. After the events of the Onslaught Saga, and the assassination of Graydon Creed, Bastion garnered enough political and public support to begin the global covert war against mutants known as Operation: Zero Tolerance. The US Government implemented Operation: Zero Tolerance, a plan suggested and overseen by Bastion.

He was raised by his foster mother Rose Gilberti as her human son. But it is depicted that Bastion was really cruel to her, terrorising her.

Operation: Zero Tolerance's objective was to capture and eliminate All mutants. To this end, Bastion created Prime Sentinels, implanting humans with nano-technology. This new generation of cybernetic Sentinel was the first of its kind and incredibly effective. Thanks to their human appearance, they were able to serve as sleeper agents and get the jump on the X-Men. Bastion was able to take over the X-Mansion; capturing some of the X-Men, learning valuable mutant intel, and stripping their home of its technologies. His original plan was to recover and use Xavier Protocols, with this data he could seek and destroy every mutant on earth, nevertheless Cable was able to stop him and destroy a great deal of the sensitive info. However with Xavier captured, Bastion tried to fool him and get access on the real information behind the protocols. Once the origin of Prime Sentinels became known, International support for Operation: Zero Tolerance was withdrawn and the U.S. Government declared an arrest warrant for Bastion, pushed forward by Senator Kelly convictions.

Originally, Bastion was a mystical amalgam of two hyperpowerful Sentinels: Master Mold and Nimrod. As such, he had a variety of abilities designed to locate, hunt, negate, capture, and destroy "Mutant threats". He was able to detect all mutants (within an approximate range of 20 miles), had enhanced strength, flight via jet boots, and could fire concussive or disintegrative blasts from his hands and chest. His Master Mold programming gives him complete control over any and all Sentinels and a unique take on it's Sentinel Production abilities, being able to create Prime Sentinels; humans outfitted with nanorobotic enhancements. He was also able to interface with any computer system within his undisclosed range, accessing its data and controlling its programming. His Nimrod programming gave Him a higher degree of intelligence than most Sentinels; He was able to assess Mutant threat levels and implement counter-measures when attacked. He was able to self-repair from most physical attacks, and was immune to all psychic attacks.
