History Recap / BatmanTheAnimatedSeriesE6TheUnderdwellers

* AdultFear: Batman is logically angry when Frog picks up and plays with a decorative gun on the wall of Wayne Manor, since it could have been loaded; though realistically, if anybody would know you should never store guns loaded, it would Batman. There is also the matter of children being abused, enslaved, and demonstrably ''tortured''. As punishment for talking, a child who has been living underground in the dark is shoved into a brightly-lit room and kept there for several hours.

* EvilCannotComprehendGood: The Sewer King can't understand why Batman would bother saving his life.

'''Sewer King:''' ''NEVEEEEERRRRRRRRRRRR!!''
* {{Hypocrite}}: The Sewer King calls Batman a "costumed freak." Please; he has on some hacky pirate outfit, and he's taking shots at Batman?

* SuddenlyVoiced: Frog gets a line at the end of the episode.

* WouldHurtAChild: Dear ''lord''. The Sewer King keeps them as slaves and treats them like dirt. Hell, he locks them in an extremely brightly-lit chamber when they get on his bad side (not that he ever has a particularly ''good'' side). The most despicable part may be his claim that he's helping them.

* MonsterOfTheWeek: The episode spotlights a villain called the Sewer King who never appears again. He is sufficiently creepy for a Batman villain, but it's just as well he never returns, since he is really only good for one story (that is, showcasing [[SlaveryIsASpecialKindOfEvil the evils of child slavery]]).

* WouldHurtAChild: Dear ''lord''. The Sewer King keeps them as slaves and treats them like dirt. The most despicable part may be his claim that he's helping them.

* SaveTheVillain: Given the nature of the villain's crime, Batman seriously thought about averting the trope this time but it was eventually played straight.

!!Tropes:

* AbsurdlySpaciousSewer

* BerserkButton: Batman is ''ABSOLUTELY FURIOUS'' when he learns how Sewer King treats the orphans. He's so angry, in fact, that he's ''extremely'' tempted to actually break his no kill code.
--> '''Batman:''' "I don't pass sentence. That's for the courts. But this time. ''This time'' I am sorely tempted to do the job myself!"

* EvilCannotComprehendGood: The Sewer King couldn't understand why Batman would bother saving his life.

* HonorBeforeReason: When Sewer King is falling into his alligator pit (but then again, maybe he just knew his alligators wouldn't attack him).
-->'''Batman:''' Grab my hand!
-->'''Sewer King:''' ''NEVEEEEERRRRRRRRRRRR!!''

* MonsterOfTheWeek: The episode spotlighted a villain called the Sewer King who never appeared again. He was sufficiently creepy for a Batman villain, but it's just as well he never returned, since he was really only good for one story (that is, showcasing the evils of child slavery).
* MookHorrorShow: A kids version as Frog attempts to escape Batman through the sewers that he knows like the back of his hand, only to find there is no escape from the Dark Knight no matter where he goes.
** The Sewer King has an adult version as he learns to his growing terror how ''relentless'' Batman can be when he chasing a villain down.

--> '''Bruce Timm''': ''"It's [[Creator/StudioJunio Junio's]] weakest episode, we almost didn't use them after that. It was the first one that came back that really looked totally unlike our show. It was very [[{{Animesque}} Japanese]]. But I'm glad we did use them again, they've done great work."''
* PapaWolf: Batman was ''enraged'' by Sewer King's crimes against the orphans.

* SomewhereAHerpetologistIsCrying: It's extremely unlikely Batman, even at his peak strength, would be able to overpower the bite of an alligator (which may reach almost 3000lbs in bite force value).

* ThouShaltNotKill: Batman still goes by this, but he let the Sewer King know that he was sorely tempted to break it this time.
** Notably, when they're fighting earlier in the episode, Batman inadvertently causes the Sewer King to fall into the pool of water they're fighting above. Batman sees the alligators going into the water after him, thinking that they're going to eat the Sewer King...and Batman simply comments on [[KarmicDeath how appropriate a fate]] it is for him.

--> '''Batman:''' "I have ''one rule'' that I never break. You... ''tempt me.''"

* OffModel: To the point where the animation company behind this episode was almost fires for it.

--> '''Bruce Timm''': "It's [[Creator/StudioJunio Junio's]] weakest episode, we almost didn't use them after that. It was the first one that came back that really looked totally unlike our show. It was very [[{{Animesque}} Japanese]]. But I'm glad we did use them again, they've done great work."

-->'''Sewer King:''' Neveeeeerrrrrrrrrrrr!!

-->''Batman:'' Grab my hand!
