They can still do the Black Noir twist from the comics in ‘THE BOYS: MEXICO’
Black Noir is the only member of The Seven they’ve ever replaced. He’s an integral Supe in the eyes of Vought. Imagine they create Black Noir III and this time he actually is a clone of Homelander, but a lobotomized one. That way they’ve successfully pacified their biggest weapon with no chance of him turning on them. Could be a solid antagonist for the first season of ‘THE BOYS: MEXICO’ and gives Antony Starr a chance to return to the franchise for a single episode reveal (then they can keep the mask on). There are a lot of ways they could execute this ngl. The freedom of this concept could be fun!
