  • This is a showcase of the superhero community. A generous amount of action, serious crisis coupled with some light hearted dialogues, and great lines delivered by the characters. A fun episode to watch.

  • An entertaining episode, that is more significant for the ongoing storylines (THe military not trusting the JLU), but not without its entertainment value.

    • The Atom: Amazing. Show (Eiling) a weapon that destroyed its creators and every other thing it saw and he wants to play with it. What's to stop history from repeating itself right here on Earth? Superman: We are.

    • The Atom: Batman, can you hear me? It's a war machine. Batman: What was your first clue?

    • Batman: Batman to all points. I could use some air support. Since I can't fly. At all. (still falling) Now would be good.

    • Batman: Where's the Atom? The Atom: (in Superman's ear) It's getting sweaty in here...

    • The Atom: I'm going to lay here for a while, Katie. I'm old now, and I get tired.

    • There is no Goldhanger in the United States. There is a town named Goldhanger in England - Warren Ellis lives in England, apparently close to Goldhanger, Essex.

    • Character bios: General Eiling, The Atom

    • Warren Ellis Warren Ellis is a famed writer of comics and graphic novels, best known for Global Frequency (which was the source for an aborted WB network pilot originally set for early 2005). He also worked on Transmetropolitan and Planetary, a PC game (Hostile Waters) and any number of other works. This is his first work on a WB animated series.

    Trivia (16)

    • After Batman ejected himself out of his jet we clearly see that Superman saved him from smashing into the ground. Superman carrying Batman is flying to meet Wonder Woman in ground. In the next scene we see Batman fighting in the battlefield behind Wonder Woman. Then in the next scene we see Superman still carrying Batman arriving to the battle field to meet Wonder Woman. How is possible that Batman in the previous scene was already in the battle field fighting if Superman has not arrived with him?

    • When Superman looks down to see Wonder Woman's Javelin unloading, we see Green Arrow, Crimson Avenger and Ice laying down some covering fire. However, Ice is shooting yellow energy blasts, not ice blasts.

    • As the Atom is discussing how the nanites replicate, in the background you can see Fire in the back, holding some kind of black pistol (or it's in shadow) and firing flames from it. Except she doesn't use a gun, and a few seconds later there's a shot of her projecting flame from her hands in her normal manner.

    • It's established the drones need to "consume" materials to replicate. But after Supergirl heat-visions one, they just...regrow, to the same size as before. There's no signs that the ground around them is missing any material that they used to reconstitute itself.

    • When Wonder Woman is fighting the drone at the end, it goes inert and she throws it off, and there are no other drones near her. When Superman and Batman come rushing up, there is at least one other drone laying close to her on the ground nearby.

    Allusions (5)

    • Atom's Intro Atom's introduction in this episode is very similar to his introduction in the graphic novel, The Dark Knight Strikes Again. In that comic, a captive Ray Palmer is in what appears to be the middle of the ocean. He is attacked by a serpent, but is rescued by Batman's new sidekick, Catgirl. It is then that you find out he was shrunken down and kept in a petri dish. Similarities? Both appear in a vast expanse of water, battle a microscopic serpent, and turn out to be in petri dishes.

    • The Brave & The Bold There are several interesting sub-teamups within the fighting groups. Vixen, Vibe, and Steel II are all seen fighting close to each other - they were members of the "Detroit Justice League" in the comics. And the Shining Knight and Vigilante team up - in the comics, they're both members of the Seven Soldiers of Victory (and S.T.R.I.P.E, who was a member as Stripesy, later joins them, as does Stargirl, filling in for the Star-Spangled Kid). Green Arrow and Crimson Avenger also fight side-by-side - they were members of the Seven Soldiers as well (pre-Crisis).

    • Batman: Save it for the autopsy.
      The comment is addressed to the Atom. Interestingly, in the issue of the DC comic Identity Crisis published just prior to this episode's release, the Batman determines the Atom is considered the person responsible in a miniaturized "locked room" murder - a fact which Dr. Mid-Nite seemingly confirms via an autopsy. Dr. Mid-Nite appears in a scene just prior to this bit of dialogue.

    • Alien sound effects At several points, most noticeably when the Batman launches conventional missiles, you can hear the distinctive "alien machinery" noise used in the original War of the Worlds movie.

    • Self-replicating robots:
      The Atom mentions the theory of "self-replicating robots" developed by the mathematician John von Neumann (1903-1957).
