Other than being obsessed with wiping everything adventurous including his own team, Bradford Buzzard should’ve just gotten rid of the McDuck Clan and everyone they are close to, good and bad. His contract he created should’ve also stated keeping F.O.W.L members around possible future plans even if they win.
One of the add ideas I had in mind was for Bradford to learn how to bond more with Black Heron and be on the same page as true villainous duo for world domination. They can even pretend to be husband and wife and have Webby (April), May, and June as their daughter triplets. This also includes wiping out the memories of the McDuck Clan and every close allies she has loved. They can even take control of the McDuck fortune if it’s still there despite being erased if goals are successful. If only Bradford can express more of his villainy and keep his evil group together instead of just throwing them out after showing loyalty.
Artifacts might come in handy too after the events like the sword for Bradford to use as defense, the harp to make sure no one in the world would trick him or F.O.W.L like that. Maybe even use the Papyrus of Binding to make not just a contract but a notebook with copies if it were possible. It was just an idea to see if things could’ve been done better.
