Waspinator's Quantum Boogaloo
By having Doofenschmirtz summon a bunch of different Waspinators gave me an excuse to actually have multiple copies of him in my world, and therefore be able to actually USE all the Waspinator figures. Having them end up quantum entangled and therefore a hive mind was just a side effect that I figured would happen because of how they arrived. Plus, it would be an interesting character feature. Something to make "him" distinctive.
