He was high-shouldered and bony; dressed in decent black, with a white wisp of a neckcloth; buttoned up to the throat; and had a long, lank, skeleton hand, which particularly attracted my attention, as he stood at the pony's head, rubbing his chin with it, and looking up at us in the chaise.

Following a will-o'-the-wisp resembling a child, he is led to a hermit dwelling in the wilderness, under whose instruction he lives for a time.

Harrow continued providing services to villains like Living Laser, but when Will o' the Wisp sought removal of his power, Harrow implanted a surgical device to extort him into theft. When the Wisp rebelled while fighting the intervening Spider-Man, Harrow's device temporarily dissipated him.

Harrow accepted a Roxxon Oil contract to create synthetic automated soldiers; to this end, he again extorted industrial crimes from Will O'The Wisp.

Surreptitiously seeking Spider-Man's help, the Wisp instead encountered the hero's clone Ben Reilly, who removed Harrow's implant when the Wisp assumed intangible form, but not before Harrow forced his catspaw to release Dragon Man from custody.

When Harrow remotely guided the powerful android to him, Reilly and the Wisp followed and destroyed Harrow's base.
