[1] Wisdom is a British Secret Service agent with the mutant ability to throw "blades" of energy ("hot knives") from his fingertips.

Pete Wisdom was initially created by Ellis and drawn by Ben Dilworth, in a pitch for Electric Angel for publisher Trident Comics.

[2] Later, at Marvel, Wisdom formally debuted, his first appearance was as an agent for the British covert organization Black Air in Excalibur #86 (February 1995).

He borrows Excalibur transport to reach and help an old friend, being forced to take Kitty Pryde with him; the two of them end up investigating Black Air's "Dream Nails" facility and the horrors within, and Wisdom is almost tortured to death by one of his employer's agents.

Both Wisdom and Excalibur are able to expose Black Air's links to the Hellfire Club, cripple the organization, and prevent its grand scheme.

[10] After Excalibur, and now sporting an unnecessary eye patch to look sexy, he organizes a group of former intelligence operatives to strike out at black-ops agencies and individuals, and requests X-Force's aid in recovering a cybernetic brain from Genosha, fighting Magneto in the process.

[15] As a result of his work, he ends up in an arranged marriage with his teammate Tink (a fairy) to cement a treaty between the United Kingdom and Otherworld.

[16] He begins a romance with teammate Maureen Raven, an Ulster-born psychic, but is eventually forced to kill her to end the Martian invasion of Britain.

Now owed a boon by the dark forces, Wisdom is able to have a magical anti-Skrull shield erected around the British Isles, which leaves the nation under constant threat of the supernatural.

[17] MI-13's first battle is against the Duke of Hell Dr Plokta, who gains power when people willingly sell their souls to live in their heart's desire; Wisdom is tempted with the fantasy of Kitty, Maureen and everyone he had gotten killed still being alive.

Despite an initial routing, he devises a successful tactic of using misinformation, a staged defeat, a blackmailed Plokta's dream corridors, and pre-emptive strikes to prevent Dracula and his invasion force from realising the UK still has a magical spell that requires a vampire to be invited into its borders.

The bulk of the vampire army is destroyed in an instant: Wisdom says that Dracula thought he was playing chess but you would only do so if you "don't care about the pieces... [otherwise] you cheat".
