History WebAnimation / Batmetal

%%* RuleOfCool: The entire videos can count as this.

* GutturalGrowler: Batman's non-singing voice is still that way, thus Alfred justified using subtitles while talking in the [=BatUpdates=].

** Batman went from the World's Greatest Detective to a guttural simpleton that can barely string sentences together. The Robin's are mostly unchanged, save for Jason and Damian becoming more cheerful.

* AllDrummersAreAnimals: Damian Wayne[=/=]Robin, the most socially maladjusted member of the Batfamily (in the absence of Cassandra Cain maybe), tears up the drums like there's no tomorrow.

--> "Oh hi Barbara. Good to see your butt--I mean you're back."

--> '''Robin:''' We can't just get out of the car, right?
--> '''Nightwing:''' Bruce don't get me wrond but...

* GagLips: Batman’s lips are in a perpetual duck face, even when he’s a child at his parents’ murder.

* GutturalGrowler: Batman’s non-singing voice is still that way, thus Alfred justified using subtitles while talking in the [=BatUpdates=].

* NippleAndDimed: {{Averted}} in Forever. It's only for a few frames, but you can clearly see Batgirl's nipples before it cuts to her stripping her pants off.
* NoHoldsBarredBeatdown: Poor, poor Ariel. She and the other kidnappers get brutalized by Batman and crew. [[spoiler: But she gets better in ''Forever'' thanks to a Lazarus pit.]]

* TheSmurfettePrinciple: Despite roping in quite a bit of the Batfamily (Dick Grayson[=/=]Nightwing, Jason Todd[=/=]Red Hood, Tim Drake[=/=]Red Robin and Damian Wayne[=/=]current Robin), it takes until the third installment to bring in ''one'' version of Batgirl.

Aside from that, they also made parody videos for ComicBook/TeenageMutantNinjaTurtles and VideoGame/{{Overwatch}} titled [[https://www.youtube.com/watch?v=SdWxdhXnDgw Jack Black Mutant Turtles]] and [[https://www.youtube.com/watch?v=ucRPoTNEbUY OVERWHAT]], but they're not actual music videos, mind you.

** [[WesternAnimation/TheLittleMermaid Ariel]], [[WesternAnimation/SpongebobSquarepants Spongebob and his friends]] and other cameos went from friendly sea creatures that can't harm flies to murderous individuals willing to torture Aquaman with glee.

* AffectionateParody: Of Batman (of course) and animated bands. And it's awesome!

* {{Gainaxing}}: Unusually for this trope, it happens with ''butts'' way more than boobs, until ''that'' becomes the usual.

* PacManFever: ''Batmetal Forever''. Damian Wayne is first seen playing an 8-bit side-scroller shoot-em-up ''on a Nintendo Switch''. Bruce plays the same game in the credits

* HardHead: Batman has one, to the point he can bounce down on a staircase on his head in ''Batmetal''

* AllMenArePerverts: Can't really help but stare when Batgirl is a walking ShamelessFanserviceGirl (save for Jim Gordon). Red Robin and Batman are more obvious in perving her. Oh and Batman just loves to shove his face into breasts.

** Deathlok themselves (with Brandon Small's blessing) appears at the start of ''Batman Forever'' looking at Batman rocking on before crushing their fans.
