Without a cannon, he'll just be a regular logistics hero, like Pyre, for example. That is, he'll still be a hero that creates imbalance, but not as much as with a cannon. It feels like you didn't read "NOT a starting hero."
Oh, I just forgot that he's a logistics hero. However, I don't see a reason why Pyre shouldn't have his machine taken away if it's taken away from Jeremy in any way.
