Honestly having trouble thinking of a good foil to Henry/Ant-Man. If Pym Particles are a wide kept secret, this cut's his possible rogue gallery in half. One idea that sticks out to me is Whirlwind, a mutant who can summon and control hurricane/cyclone style winds and send his foes flying. He's fought the original more then a few times and they both kind of hate each other for the most part. Other then that, maybe a collective swarm of Micro-Yellowjacket drones? Maybe we could just pair Vision up with Ant-Man and Ultron-99 and keep it simple. Whatever you guys think.

Just because they're a secret from the wider world doesn't mean they're a complete secret, see the new ant-man movie :P So it is possible that someone from that corporation could have (Eventually) replicated them. What I meant in "Secret" is that they're not known to the wider world, or corporations like Alchemax which is why there aren't miniature people running around comitting espionage all the time.

Perhaps Alchemax will find the old Pym particle research done by Cross? Or maybe they already have but we just don't know it yet... dun dun duuuuun (That's upto KL).
