Infinaut
The Infinaut's second manifestation happened in 1998, in Machu Picchu, and it was interrupted by Adam Brashear together with his son Kevin using an anti-matter-powered rig. Were the Infinaut capable of materializing at full size, he would destroy the Earth. The Infinaut attempted to arrive to the Earth six other times in the following decades.
At the time, Brashear was part of the Mighty Avengers, the Macronaut tried to land in Quezon City, but was repelled by the Triumph Division.Years later, a vision from the Inhuman procog Ulysses Cain alerted Dr. Brashear of the Infinaut's imminent ninth manifestation eight days before it happened.
With a week to prepare, Brashear and his response team known as the Ultimates built a Pym Particle accelerator. With the help of Giant-Man, when the Infinaut appeared, the Ultimates managed to anchor him and reduce his size to that of an average human, allowing the Infinaut to enter this space without dire consequences for the Earth or himself. When the Infinaut managed to communicate with the Ultimates, he expressed his happiness for meeting them.
