WARNING: The following contains spoilers for Ant-Man #2 by Zeb Wells, Dylan Burnett and Mike Spicer, on sale now.
Being a former criminal himself, Scott Lang has always been willing to work with other villains who are trying to help people. But while some of them (like his former romantic relationship with Beetle) can be slightly open about their connection, his newest ally is someone that he really doesn't want people to know about.
Ant-Man just became very reluctant friend to the Swarm, a sentient Nazi swarm of bees, which might come in handy given his newest enemy.
After finding Swarm in the previous issue and quickly defeating him by utilizing entire beehives to fight him off, Scott was shocked to find that the real threat was the three new swarms of bugs that had taken on humanoid forms. Vespa, Thread, and Tusk quickly try to kill Scott and Swarm as interlopers, but the two are able to escape when Scott enlarges a bee with his Pym Particles. While the bee holds the creatures at bay, Swarm tries to explain why the creatures are after him. The three are like Swarm, but without the remaining humanity in them. They kidnap him so he can remake the ray that turned him into Swarm in the first place. Seeing Swarm as an abomination for his human half, he's been fleeing them and their leader.
Ant-Man and Swarm are forced to take on the mysterious and dangerous monster known as Macrothrax. The mysterious humanoid bug monster possesses great strength, psychic abilities, and a desire to see insects wash over humanity and destroy it. While Ant-Man tries to talk him down at first, but it doesn't end up working. Things only get worse when the being probes Scott's mind and finds out about the existence of Pym Particles and how they could turn the insects into giant creatures more easily capable of taking down humanity. Scott and Swarm are able to escape the insect creatures, although not by much. However, Ant-Man isn't exactly happy afterward, thanks to how Swarm interprets their "team-up".
When Swarm begs Scott for his help in fighting the creatures, Ant-Man is quick to point out that he's doing this to stop villains but he's also definitely not doing this to help Swarm was previously a Nazi beekeeper who escaped retribution following the war by fleeing Europe for Brazil. Ant-Man wants no part in helping a former Nazi, he's just trying to fight the obvious supervillains. Helping Swarm is incidental. To his credit, Swarm at least seems to recognize why Ant-Man has no interest in being his friend.
But when Ant-Man is knocked out while trying to escape the creatures, the villainous Swarm makes sure to protect Ant-Man and save him. Bringing him back to the bee-keepers who hired Ant-Man in the first place, Ant-Man restores to his natural size. Swarm is quick to call Scott buddy, despite what Ant-Man says about them not being friends. He makes sure yo yell that Ant-Man is now his "dear friend" and that he owes Ant-Man a great debt. Ant-Man keeps yelling at him that they are not friends, even as he flies off. Ant-Man has to recognize that teaming up with a Nazi bee man probably isn't the best look. But to be honest, having the ability to call in Swarm for help might come in a lot of handy down the line.
