the would-be Avengers to call him again in six months. Captain America summoned Fabian Stankowicz back to Avengers Island to serve as the group's inventor. Fabian agreed and assisted the Avengers in recovering Red Skull's fourth sleeper from Massachusetts. Machinesmith brought the sleeper to life which was defeated by Captain America. Captain America gave Fabian the skull of Ulysses Bloodstone. Fabian attached a radiometer to it so that it can help to locate the fragments of the Bloodstone. Captain America took off immediately to begin his search. During the "Acts of Vengeance" storyline, Fabian was present with the Avengers Island staff and Quasar discussing the recent attack on the Avengers when Avengers Island is suddenly attacked by Doctor Doom's killer robots. Fabian donned the Mecho-Marauder armor to help fight the killer robots. He managed to defeat some of them and then had to be rescued from the rest by Quasar. Fabian and the rest of the staff were evacuated from Avengers Island before it was destroyed by some explosives that the robots planted. Upon returning from his quest, Captain America learned from Fabian and the rest of the support crew what had happened to Avengers Island. The support crew moved their base of operations to the sub-basement of the original Avengers Mansion. When Namor the Sub-Mariner turned up under the control of the Controller, Captain America paired Fabian up with Hank Pym to find a way to remove the Controller's control device from Namor. Thanks to Henry Pym's success at removing Controller's control device being removed from Namor, Fabian watched as Namor came to his senses. When Captain America ends up attacked by mechanical tendrils upon entering the sub-basement, Fabian apologized for that stating that he was testing them out. Fabian then helps Captain America research some information about Magneto. When the Daily Bugle was leveled by Graviton, the Avengers were called in to help Damage Control during its worker strike. Fabian tried to use some pulleys to help She-Hulk which proved unsuccessful. Captain America had Fabian and John Jameson occupy Diamondback while he met with Eric Masterson. Fabian welcomed Captain America back to Avengers Mansion upon his return. Mother Night used her hypnotic vision of Fabian's mother to sway Fabian to place some bugs throughout Avengers Mansion so that she can collect information. Fabian later joined the Avengers in attending a party in Sersi's loft when Fabian is visited
