Depends, imo. If Blackbeard knows that Im exists (certainly possible), I think it's likely Blackbeard can outmanouver him and become the main antagonist, but not guaranteed. If Blackbeard doesn't, I wouldn't be surprised if Im turns out to be very strong and very skilled chessmaster who can be more dangerous than even Blackbeard.

Frankly, Im has to be dangerous. There's no way Oda can drop a bombshell like this and have it end up being anticlimactic.
