Recap: Justice League Unlimited S 3 E 5 Flash And Substance
When the Flash gets a museum opened in his honor, courtesy of the grateful residents of his native Central City, four members of his Rogues Gallery
take it upon themselves to kill him on the eve of the opening. Batman and Orion, who've come to witness the opening at Flash's invitation, must now help the Scarlet Speedster repel the villains—and they get to witness just how Flash operates on his home turf as a superhero.
- Break Out the Museum Piece: by no means an antique, but Captain Boomerang snatches a boomerang from a mannequin display of himself.
"Hey, been lookin' for that."
- But for Me, It Was Tuesday: the Rogues are gunning for the Flash's head, which is taken seriously by everyone except the Flash.
"Dude, the bad guys went down and nobody got hurt. You know what I call that? A really good day."
- Continuity Nod: Several abound in this episode.
- The Flash Museum shows a display of Flash racing around the world with Superman. This took place in the Superman: The Animated Series episode, "Speed Demons."
- Flash's Lightspeed Bar standy, which Orion destroys when it startles him, references the episode "Eclipsed."
- The episode "Task Force X" and Captain Boomerang's involvement in the titular group are referenced when Boomerang himself tells his fellow villains that he got a deal that "got (his) sentence down to five years," and again when Batman tells Flash that Amanda Waller had informed him about Boomerang leaving the team.
- Did You Just Punch Out Cthulhu?: Captain Cold manages to hold his own against Orion, defeating him by freezing him on the spot. For the record, Captain Cold is a normal human with no super-powers of his own and who relies on a cold-gun to fight, while Orion is one of the New Gods and has fought in close combat with Darkseid on at least one on-screen occasion.
- Exactly What I Aimed At: Batman fires a flare gun at the Rogues, only for it to stumble into the Mirror Dimension. The oblivious Rogues gloat at how Batman missed, except that the flare was actually meant for the Flash, who was lost in the Mirror Dimension.
- First Name Basis: the Flash knows every single denizen of his City of Adventure by name.
- Friendly Enemy: Flash is this with Trickster; in fact, their interaction provided this trope's page image at some point. It's also a source of confusion for the battle-hardened Orion.
- Genre Savvy: Captain Cold finally decides that attacking the Flash Run the Gauntlet style is stupid, and convinces his fellow Rogues to attack him all at the same time.
- Harmless Villain: The Trickster, to the point that none of the Flash's other rogues take him seriously.
- An Ice Person: Captain Cold.
- Insane Equals Violent: Inverted with the Trickster - the mentally ill Rogue is the most harmless. It's a pointed contrast to The Joker, with whom the Trickster shares a voice actor.
- Lampshade Hanging: Wally has a drawer full of costume rings. He mentions to his companions that the trouble in using one is in trying to put the costume back in.
- Literally Shattered Lives: a family-friendly sort; Mirror Master escapes into one of his mirrors, a split second before Batman throws a Batarang in its direction, shattering it, trapping Mirror Master in that particular mirror.
- The Mentally Disturbed: Trickster, at least in this continuity, has super-villain delusions and relies on medication to keep himself in check. Flash actually has to point out to him that he's wearing his villainous costume for him to know he's had another episode of this.
- Mythology Gag: Several abound inside the Flash Museum alone, including the presence of Jay Garrick's (the first Flash in the comics) World War 1 helmet and Kid Flash's costume (Wally was the first Kid Flash in the comics). There's also the presence of the Flash's costume ring, which was used in the comics to store the hero's costume inside.
- Continuing a Running Gag in the comics: the Flash Museum getting totaled, even on opening night.
- No Medication for Me: Trickster has gone off his meds, only taking them when he "feels down". Flash talks some sense into him about that, pointing out that he'd donned his supervillain costume without realizing it.
- Noodle Incident: the Rogues discussion in the Bad-Guy Bar; Mirror Master gets called out on two embarrassing incidents.
- Not-So-Harmless Villain: yes he actually did nothing in the episode, but the Trickster's ramblings about a Death Trap just after his fellow Rogues abandon him? It's actually a Cruel and Unusual Death.
- Oblivious to Love: For a guy who's known for hitting on the ladies at every chance, Flash is amazingly oblivious to Linda Park's not-so-subtle crush on him; when she finally gets to outline it to him, he's a bit embarrassed and covers with a joke.
- Stuff Blowing Up: The Trickster comes up with a ridiculous plan to grease the bottom of fake vomit and get the Flash to run over it so he slides into a wall of spikes. "And then... Everything explodes!"
- Tempting Fate: Orion disses Flash and mentions that he's never going to the museum opening. One Death Glare from Bats later, and...
Orion: ...it's not black-tie, is it?
- Unwitting Instigator of Doom: Linda accidentally sets the Flash up for an ambush when using her compact, which the Rogues use as a portal into the museum under the noses of Batman and Orion.
