I think that it would be Flint honestly. In the first episode of Arise, Serpentor, Arise Flint rattled off the chain of command and it was Hawk, Duke, Flint, and Beachhead. However I suppose anyone could be recommended. Funny you should start this thread bravo, I was thinking the same thing but more of what its affect would be on the entire Joeverse, they couldn't just bring Duke back to life like OP.
