Although native to the planet Broi in the Wyllys system of the Milky Way galaxy,[3] the Tsiln who came to be known as Gog was born in the realm of Haizlip and given to a Haizli prince as a pet, while another Tsilin was given to the princess. When the Haizli engaged in civil war, the loyalist populace was evacuated; however, the cargo ship carrying the Tsilin crash-landed on Earth.[2]

Gog with his original master

The crash site was discovered by Kraven the Hunter,[4] who named the creature after the biblical Gog,[3] and raised it as his own,[4] until one day he had it take Gwen Stacy hostage when she, J. Jonah Jameson, Peter Parker, and Richard Calkin were on a mission in the Savage Land.[5]

With the help of Ka-Zar, Spider-Man, in an attempt to rescue Stacy, seemingly outwitted Gog when the alien fell into quicksand,[4] but Gog was in fact rescued by Ka-Zar's brother, the Plunderer. The Plunderer used Gog to help commit crimes, until the creature grew bored, and wandered away.[6]

Gog was later forced by Doctor Octopus to join the third incarnation of the Sinister Six. After the team's defeat, Reed Richards shrunk Gog down to a smaller size,[7] using Pym Particles,[2] and returned the creature to the realm of Haizlip.[3]

However, Gog's new diminutive size left him an outcast and he fled, ending up on Earth-177. He came under the mental control of the native Doctor Octopus and Sinister Six. He was freed by the Web Warriors after they revealed the truth to him and restored him to his true size and returned him to Haizlip.[8]

Watching his master die

There Gog witnessed the end of the Haizli civil war, as the queen had discovered the Lifeline Tablet,[2] which had been banished to her realm by Doctor Strange,[9] and she believed would aid her faction in battle; however, the prince died in the invasion. The queen then shattered the Lifeline Tablet and tasked Gog with returning the fragments to Earth, asking that he guard one piece to ensure that it did not fall into the wrong hands.[2]

After Boomerang rendered Gog unconscious with a sleeperang, Peter and Jamie fashioned him with an Inhibitor Collar to prevent him from using the Pym Particles, then Peter and Fred brought Gog home to Randy Robertson for the trio to keep as a pet.[10]

  • Superhuman Strength: Gog possesses vast physical strength and at 30' he could lift 75 tons while at 300' he could incapacitate the Hulk and Ghost Rider with a swat of his hand.[11]
  • Superhuman Durability: As a Tsiln Gog possesses vast superhuman durability.[11]
  • Size Reduction: Because of the Pym Particles in his bloodstream, Gog can reduce himself in size, down to just a few feet tall.[10]
  • Size Addition: In addition to being able to shrink, Gog can grow in size as well, up to a towering three-hundred feet tall.[3]


  • Gifted Intellect: Despite preferring brute force Gog is actually very intelligent.[11]



A pair of bracelets that, when touched together, could teleport Gog to the location of his choosing.[11]


  • Gog continued growing in size throughout the years. During his first encounter with Spider-Man, he was 30'0" tall; however, prior to Reed Richards' shrinking of Gog, the creature was a full grown 300'0" tall.[3]
  • When and how the events of Amazing Spider-Man (Vol. 5) #42 possibly relate to those of Spider-Man: Enter the Spider-Verse #1, in which Gog traveled to Earth-177 and joined that universe's Sinister Six, remains unclear. Both stories take place after Reed Richards shrunk him down and sent him home in Spider-Man #23. While it could be presumed he ended up on Earth-177 and then returned home after that, Spider-Man makes no mention of the events on Earth-177 when he next meets Gog and the ability for Gog to speak full sentences and his growth into an adult have seemingly disappeared.
