Devoured by the Horde: The most dangerous thing about fighting the Ant Amazons is that they're mindless berserk Amazons in a large group. Kota would've suffered this fate had he not managed to set off the sprinklers and fumigate the entire building with Anti Amazon gas.
It Can Think: While not seeming to retain her humanity or be quite as smart as a normal human, the Queen is the first Amazon to imitate one and use complex plans to lure them into a trap where she can kill them. She's also smart enough to retreat and eat to regain her strength after getting attacked by Haruka.
Averted for the drones. Unlike their queen, they're all dumb as bricks and can be distracted by loud noises. That moment of distraction saves Kota's life when he sets off the sprinklers and by proxy the fire alarm.
