Spider-Seeker

A Spider-Seeker is a robot created by Alistaire Smythe to seek out Spider-Man for his benefactor.

History
The Spider-Seekers were created by Smythe and given to an employer who assigned six to Montana. Three exploded when chasing him up a skyscraper and Spider-Man crashed two into each other. The sixth escaped and inadvertently helped Spider-Man defeat Ox by shooting him and then being kicked into his suit, frying its circuits.
