Forgetting that Bumblebee can already shrink herself, Robin invites The Atom to help them defeat The Brain's giant robot. The Atom then challenges Bumblebee to a shrink-off to decide which one of them is the best small hero.
- Achilles' Heel: Robin learns that the Brain is building a mech suit that's completely invulnerable save for a tiny exhaust port, with Cyborg directly comparing it to the Death Star in Star Wars. When The Brain attacks and they see he's put a tape filter over the exhaust filter, Bumblebee and Atom notice the suit's also top-heavy with tiny limbs, and they find a second heel: transforming to normal size and then tipping it over, with The Brain unable to stand up after.
- "Fantastic Voyage" Plot: Robin attempts to set one up as part of the shrink-off, swallowing a bomb and challenging Bumblebee to remove it, but she considers it nasty and refuses. Becomes a Brick Joke after The Brain is defeated and Robin suddenly swells and explodes because the bomb was never removed.
- Good Versus Good: Bumblebee and the Atom challenge each other to a shrink-off to determine which one of them is the best small hero.
- Running Gag: Starting from the moment Atom opens the door to Titan Tower, Robin keeps accidentally stepping on and squishing him.
- Title Drop: Atom claims that he's better than Bumblebee because, unlike her, he still has "the strength of a grown man" after shrinking.
