Otto Octavius

Otto Octavius is an absolutely brilliant scientist to the standards of any world, but he comes from a world that was more mundane than the Marvel Cinematic Universe, two decades in the past at that. As such, the new world he finds himself in is rife with geniuses that develop technology similar to or better than Otto's own. The Iron Spider's nanotech rather easily overrides the operating system of his tentacles.
