"The old ways are better. Simple. Built to last. Like this submarine."
Anton Ivanov[src]

The Watchdogs Submarine is owned and operated by the group, the Watchdogs under the leadership of Anton Ivanov.


Acquired by the Superior

"Anton Ivanov, a reclusive industrialist with interests all over the globe."
"Could be the source of Nadeer's financing."
"He's also an avid collector of military antiques, so guns, tanks, and... a submarine."
Daisy Johnson and Phil Coulson[src]

While enriching his collections of old military equipment, Anton Ivanov purchased a submarine, which he turned into a mobile base of operations for the anti-Inhumans hate group known as the Watchdogs.[1]

Multiple Kidnappings

"I am the captain of this ship, and you are my prisoners. If you cooperate, you will be treated as welcomed guests. If not, you will be removed... piece... by piece."
Anton Ivanov to Billy Koenig[src]

After he betrayed S.H.I.E.L.D., Holden Radcliffe allied with Ellen Nadeer and the Watchdogs. Radcliffe and Aida moved to operate from the Watchdogs Submarine, taking Melinda May trapped in the Framework with them.[2]

The Watchdogs later kidnapped Billy Koenig in an attempt to reclaim the Darkhold. Koenig was imprisoned in the Watchdogs Submarine, where Radcliffe posed as the Superior's prisoner as well in order to make Koenig talk. However, feeling that Koenig would not cooperate, Radcliffe used some Framework equipment to read inside his memories to know where the Darkhold was.

This enabled Radcliffe to locate the Labyrinth, although Ivanov intended to torture Koenig to confirm the intel, leading to a brief fight between Aida and the Watchdogs. Koenig was ultimately taken out of the Watchdogs Submarine to be brought to the Labyrinth, where Radcliffe reclaimed the Darkhold. Back in the Submarine, Ivanov told Radcliffe about his suspicions that Phil Coulson was responsible for all the alien-related events having recently occurred on Earth.[1]

Agnes Kitsworth was brought to the Submarine by Radcliffe in order to be connected to the Framework as her physical body was dying.[3] The Watchdogs, Radcliffe and Aida later abducted several other S.H.I.E.L.D. agents: Jeffrey Mace, Phil Coulson, Leo Fitz and Alphonso Mackenzie, who were transferred to the Ivanov Oil Platform with the Watchdogs Submarine.[4]

― The Superior to a Watchdog[src]

After the S.H.I.E.L.D. agents Phil Coulson and Melinda May escaped from the Framework and tried to take control of the Ivanov Oil Platform, Anton Ivanov decided to leave the Platform with the Watchdogs Submarine, launching torpedoes to destroy the place in an attempt to kill all the S.H.I.E.L.D. agents.[5]
