In regards to Cody, he absolutely should be a heel. Even as a face, he's often a real dickhead and unlikeable shit who outright buries his opponents on promos even though they're his own talents, always dressed to the nines, has his own entrance set and pyro, the most self indulgent entrances and promos, etc. If you see that promo he cut for the house show they were weirdly promoting very hard, he talks about being self aware and he knows people talk about all that stuff because he's Dusty's kid so he's always had to be aware of himself and his actions and blah blah. And I'm thinking, this dude really should have turned this into a heel gimmick a year ago. Where he's the complete antithesis of Dusty. He's never had hard times. He is Dusty's Kid. He's royalty. Everyone knows he's the boss, that's why he gets all this extra shit.
I find Cody in general to be somewhat unlikable even at times he was being a good face. I think he excels at being a heel anyway, and he's in a position where this heel gimmick is an absolute lay up, is very small tweaks to what he's already doing as a face, and would work especially well for his particular audience.
