Describe the technological advancements utilized by the villain, 'Chaos', and their impact on the Marvel Universe.

Chaos employs a combination of advanced temporal manipulation technology, allowing him to briefly rewind time to correct mistakes and create localized paradoxes. This has resulted in widespread instability, altered timelines, and the creation of 'Echoes' – fragmented versions of individuals trapped in repeating loops of time. These Echoes pose a significant threat to the present.
