Theory: Maximus started The Watchdogs
There are a LOT of unanswered questions about the Inhumans series, mostly due to it’s cancellation. I’ve gone through the show and came up with a few theories as to where these characters went, some world building implications, and in this theory, a few closer connections to the greater Inhumans Saga as seen in Agents of SHIELD.
Maximus is probably the most interesting character from the show. He secures a very early Loki-esq position as this trickster sort of character, trying to overthrow the royal family and rise to power in Attilan, under the pretense of an Inhuman Revolution that’s really just a front for his power grab.
In the opening of Inhumans, we see an Inhuman, Triton, being hunted down by… someone. They never elaborate who is hunting down Inhumans, just that people are. However, looking at these people hunting down Triton, they seem to have an absurd amount of military grade firepower for just some people who hate Inhumans. I think it makes the most sense for them to probably be members of The Watchdogs, given how they strategize and group up against Inhumans.
We learn later in the show that Maximus sent these people to kill Triton, as part of his plan to radicalize the people Attalin and take over as king.
While I think one kill, a life that everyone knew, would certainly be affective, I think there has to be much more to it than that. Overtime, humans have become more efficient at killing Inhumans, even before The Watchdogs were brought in by that politician in Agents of SHIELD Season 3.
Maximus is more than okay with killing Inhumans if it meant he could control the remainder, so I think it makes sense that, after The Terrigen Crisis, Maximus would stoke the flames of conflict by having a group that specifically could hunt down Inhumans by knowing where they were and what they could do, all while being backed by an unlimited resource.
This is something Maximus has done before, with the Inhuman research facility experimenting on powerful Inhumans to figure out if any of them could kill Black Bolt. He donated millions of dollars anonymously for the sake of his manipulation plan, and The Watchdogs were a much more violent and threatening aspect of that that would stand Inhumans to want to go to war with humanity, which was Maximus’s endgame of claiming the Earth for the Inhumans.
Thematically, this also ties many of the non-HYDRA threads of The Inhuman Saga together, bringing it all back to Maximus as a main villain pulling strings behind everyone’s back.
