I love the idea of Soldier Boy and Malchemical being an alternate version of Dean and Castiel.
There's the given and obvious: the casting of all four characters and how the director (Eric Kripke) is making constant references back to Supernatural in The Boys. But aside from that, it would make sense. Balthazar tells Castiel that in their universe, it is the only one in which Castiel rebels for Dean, or for the sake of context and deeper meaning, love. Malchemical himself is unwilling to put himself or his image/wealth for virtually anything, and Soldier Boy, like Dean before trusting Castiel, is quick to attempt (or, in Soldier Boy's case, succeed) in killing the Cas variant for his own cause.
It's in plain sight, honestly. I know this is kind of a dead topic now, but I really like its potential. It also kind of goes to further prove how strong Castiel's love for Dean is. Don't get me wrong, the whole 'find each other in every universe' trope is sweet, but having a love that surpasses the universal constant is incredible.
