Doctor Octopus' mechanical arms are four robotic limbs that resemble octopus tentacles, created and used by Oscorp employee, Dr. Otto Octavius. Octavius used these to create and handle highly, dangerous experiments.
Appearances and cameosEdit
In the film the tentacles make an appearance at the end as Gustav Fiers walks past them in Oscorp Tower, alongside Vulture's Mechanical Wings. They are put there as a teaser/Easter Eggs of the upcoming Sinister Six film.
