Spider-Slayer

Ultimate Marvel

In the Ultimate Marvel universe, Spider-Slayers were built by the Tinkerer under the order of General Nick Fury, to be used in case Spider-Man ever went rogue. When clones of Spider-Man begin running rampant Nick Fury and a battalion of Spider-Slayers travel to the Parker residence to arrest Peter, only to encounter the Fantastic Four and Carnage, the latter which the Slayers take down (reverting it to Gwen Stacy). The Slayers later kill a disfigured clone of Spider-Man. and imprisoned another unstable clone of Peter Parker/Spider-Man in SHIELD.^{[9][10][11][12][13][14]}

In the Ultimate Marvel continuity, the Spider-Slayers are tall (about eight feet) robots that balance on a large sphere, wield two arm-cannons, and have a sphere for their heads. They turned out in fact not to be manned but controlled remotely by the Tinkerer.

MC2

While trying to apprehend a dimension-hopping supervillain in the MC2 reality, Spider-Girl is accidentally sent into Earth-616's past, where she encounters the first Spider-Slayer. Mistaking her for its quarry, the Slayer attacks Spider-Girl, who manages to evade the machine due to Jameson and Smythe being distracted by how different "Spider-Man" looks. Spider-Girl later returns to her own universe and time, while Spider-Man defeats the Slayer in the same way he did in the original story.^[15]

House of M

In the House of M reality, J. Jonah Jameson (fearing Peter Parker would take revenge on him due to outing him as Spider-Man) has Alistair Smythe construct a Spider-Slayer to protect him. When Peter's family breaks into Jonah's home looking for Peter's journal (given to him by the Green Goblin) Jonah, using the Slayer, attacks. Hitting Peter's wife Gwen Stacy just as Peter arrives, Jonah's slayer is ripped to shreds by the hero.^[16][17]

The House of M Slayer resembled a humanoid robot with claws and a glowing core in the chest similar to Iron Man's armor. Like early models in the mainstream universe it had a view screen depicting the controller in place of a face.

What If

After Aunt May and John Jameson are killed in a space shuttle crash caused by the Chameleon, J. Jonah Jameson adopts Peter Parker, and blames the deaths of their loved ones on Spider-Man. Obsessed with taking Spider-Man down, Jameson commissions the creation of the Spider-Slayer and the Scorpion formula, the latter of which is ingested by Flash Thompson. The serum warps Flash's mind and causes him to go on a rampage, which ends when he is subdued by Spider-Man (who reveals he is Peter Parker to Jameson) and the Spider-Slayer, controlled by Jameson. Jameson realizes how irrational his hatred of Spider-Man is, and decides to help his adopted son fight crime using the Spider-Slayer.^[18]

Television

• The first Spider-Slayer appeared in the 1960s Spider-Man cartoon series. This version was built by a man named Henry Smythe. In this adaptation instead of steel coils that shoot out of the robots body, it only has two metallic tentacle-like arms, and also possesses a periscope. In the episode "Captured by J. Jonah Jameson", it pursued Spider-Man all over the city. After Spider-Man tricked the Spider-Slayer with a dummy of himself, Henry takes the Spider-Slayer back to his house to work on it.

The Spider Slayers combined in the 1990s Spider-Man cartoon series.

• The Spider-Slayers appear in the 1990s Spider-Man cartoon series. They appear as the main antagonists in the second and third episodes. In "The Spider Slayer", the Spider-Slayers being commissioned by Norman Osborn for hunting Spider-Man with Spencer Smythe at the controls. The 'Black Widow' Spider-Slayer was finally destroyed and the factory exploded with Spencer still in it. This culminated in Alistair Smythe working for the Kingpin when his father was presumed dead. In "Return of the Spider-Slayers", Alistair would go on to not only recreate the 'Black Widow' Spider-Slayer, but simultaneously unleashes the 'Tarantula' Spider-Slayers and 'Scorpion' Spider-Slayer. In this depiction, the three Spider-Slayers could join together as a massive engine of destruction. In "Tablet of Time", Alistair would build another Spider-Slayer called the "Mega Slayer", a heavily armed humanoid robot operated by remote. As punishment for repeated failures and being partially responsible for Richard Fisk's arrest in "The Man Without Fear", Kingpin's new chief scientist Herbert Landon genetically mutated Alistair into the 'Ultimate Spider-Slayer' as seen in "The Ultimate Slayer". In this form, Alistair was capable of walking again and was incredibly strong and resilient, and also had twin horns growing from his shoulders, both of which were organic laser guns. Though Alistair broke free from Kingpin's controls when Spider-Man revealed what really happened to Spencer. In "The Wedding", Kingpin used Smythe's duplicate of the 'Mega Slayer' to stop Goblin Glider-riding Robots sent by Smythe and Harry Osborn to crash Peter Parker and Mary Jane Watson's wedding. It was destroyed while helping Spider-Man and Black Cat. The Alien Spider Slayer (Mark X) was removed from the 1990s Spider-Man TV series but the design was featured in both the Animated Series Toy Line by Toy Biz and the Super Nintendo and Sega Genesis Spider-Man video game released in 1995.
• A Spider-Slayer like concept called the Sentinel Prowlers appear in the Wolverine and the X-Men animated series. The Sentinel Prowler is a prototype version of the Sentinels.
• The Spider-Slayers appear in Ultimate Spider-Man vs. The Sinister 6. There two variations: Project Kaine (voiced by Drake Bell^[19]) and the Delta-Nine Synthezoids which consist of Bone Spider and Goliath Spider (both voiced by Imari Williams^[20]) and Ghost Spider (voiced by Roger Craig Smith^[20]). Both versions are a part of a secret HYDRA project where the DNA of Spider-Man (Peter Parker) is combined with Arnim Zola's synthezoids. Kaine resembles a pale version of Spider-Man with a green mark across his chest spider symbol and highly resistant to damage with the capability of reattaching lost limbs. Bone Spider's additional ability enables him to extend his bony protrusions and claws, Goliath Spider's additional abilities give him super-strength and the ability to turn his body into metal, and Ghost Spider's additional ability enables him to teleport, become intangible, and perform bio-electrokinesis moves. They appear in "The Spider-Slayers" story-arc as a central character. Kaine makes himself known when he feeds off of Peter and Mary Jane Watson. When the two move through HYDRA's secret lab, Kaine uses more Spider-Man synthezoids in fighting Spider-Man and Spider-Woman. Following the imperfect synthezoids' defeat, Kaine traps Spider-Man and Spider-Woman until the prototype synthezoid is sliced in half by Scarlet Spider (Ben Reilly) . Doctor Octopus uses Scarlet Spider synthezoids as protection when the three Spiders move further through the secret lab only for the more perfect synthezoids to be beaten by Scarlet Spider and Spider-Woman. Spider-Man and Scarlet Spider take Doc Ock to Hydra Island where the three encounter the Delta-Nine Synthezoids in a showdown. After it's revealed that Scarlet Spider is an advanced Synthezoid version spliced with Spider-Man's DNA (similar to the Clone Saga) with implanted memories, Doc Ock reveals that Scarlet Spider was originally meant to be the Delta-Nine Synthezoids' leader. As the two heroes struggle against the Delta-Nine Synthezoids, Doc Ock (with improved Nano-tech) comes to the Spiders' aid and imprison the Delta-Nine Synthezoids. After Zola's reactivation, Doc Ock betrayed Spider-Man and Scarlet Spider and left the heroes to the clones' wrath. Zola (via HYDRA Island's nanotechnology) traps Scarlet Spider and Spider-Man, making Scarlet Spider fall into his dark side but convinces the Delta-Nine Synthezoids to not attack Spider-Man as the Web Warriors arrived. With help from the newfound allies, Spider-Man was able to defeat Zola. Escaping the HYDRA Island's destruction and placing the Delta-Nine Synthezoids into stasis pods, the Web Warriors and the Delta Nine Synthezoids go off to the Triskelion. Meanwhile, Kaine regenerates in a mutated, misshapen form with spiked tentacles out of his sides and infiltrates the Triskelion. Kaine attacks S.H.I.E.L.D. Academy and feeds off the group's energy. When Scarlet Spider attempts to overload Kaine with an energy transmitter, the process is interrupted which makes Kaine stronger. Powered up with a bulkier physique, Kaine begins dominating over the Web-Warriors, making Spider-Man and Scarlet Spider resort to assistance from the Delta-Nine Synthezoids (Bone Spider, Goliath Spider and Ghost Spider). But having gained enough intelligence to be disdainful towards humans, Kaine is able to coherce the Delta-Nine Synthezoids as the new alpha into turning on the Web Warriors. Although the Delta-Nine Synthezoids are eventually defeated by the Web Warriors, Kaine absorbs the Delta-Nine Synthezoids into his body mass, transforming into the Ultimate Spider-Slayer, a hulking hybrid of the other Spider-Slayer synthezoids. Nigh-unstoppable, Kaine attempts to absorb Scarlet Spider. However, Agent Venom rushes towards Kaine with the energy transmitter and enters Kaine's hybrid body, successfully managing to overload Kaine's hybrid form to explode into synthetic goop.
