Powerpuff Power Hour/Tropes

The long awaited Grand Finale of the 2016 Powerpuff Girls series ends with a Crossover with the 1998 original in a battle with the 2016 incarnations' enemy, Silico, as he plans to wipe out the entire PPG multiverse, along with the 2016 and 1998 universes.

Tropes
1998!Buttercup: I don't know how you're praised for your outrageous buttkicking back in your world, but I think you don't deserve to be heroes! You look like us, but you don't act like us! (to 2016!Blossom) You're an uptight, tidy neatfreak! 2016!Blossom: Hey! I am not! 1998!Buttercup: Don't deny it! (to 2016!Bubbles) You're, like, a teenage version of our Bubbles! 2016!Bubbles: Really? Am I really that mature? 2016!Buttercup: Bubs, you're the same age as us. 1998!Buttercup And you! (approaching 2016!Buttercup) You're the most selfish, self-centered, lazy, incoherent person I've ever met! You keep saying "dude" all the time, you talk slang, you call your sisters by short versions of their names "Bloss" and "Bubs", and you think anyone else's problems are far less more important than! 2016!Butterup: Dude! Just because I have those traits, don't mean I only care about myself. 1998!Buttercup: Whatever, doesn't matter! You think you're much more smarter than us, more cooler than us, more cuter than us. But what I see... is a bunch of inferiors! (The 2016!Powerpuffs have their mouths open in shock of Buttercup's words, then look at each other shamelessly)
 * Absent-Minded Professor: Mostly the 2016 incarnation of Professor Utonium than his 1998 counterpart.
 * Animation Bump/Art Shift: Despite the 2016 incarnations entering the 1998 universe (as the original series was animated by Rough Draft Studios), they still retain their Sunmin Image Pictures Co. look throughout the episode.
 * Always Someone Better: The original Powerpuff Girls are this to their reboot counterparts. The narrator lampshades this in the second act.
 * Arson, Murder & Jaywalking: 1998!Buttercup calls the 2016!Powerpuff Girls by their certain traits while calling them out.
 * Back for the Finale: Many characters from the 1998 series that hadn't made it in the 2016 series make a small appearance in the crossover. Those being:

 * Canon Discontinuity/Discontinuity Nod: The 2016 series and 1998 series are separate universes, despite the Continuity Nods to the original series in "The Wrinklegruff Gals" and "Memory Lane of Pain".
 * Cliffhanger: The 1998!Girls prepare to fight their villains after their farewell to their 2016 versions after they fade from existence (this would not have been a cliffhanger, but the fight is not seen since the ending used the Narrator's ending from the original series).
 * Counterpart Comparison: Between the Blossoms and Buttercups.
 * 2016!Blossom is more of uptight and a neatfreak unlike her 1998 counterpart.

 * Everyone Has Standards: Even though 1998!Buttercup is much more of a stubborn, untrustworthy jerk, her 2016 counterpart is a much bigger one. 1998!Blossom and 2016!Blossom subvert the trope.
 * Excuse Plot: The reboot's entire premise was made as an excuse to revive the original series.
 * Famous Last Words: When 2016!Bubbles is about to cease to exist, she wishes that she and her sisters were more like their counterparts.

 * Grand Finale: A series finale of the panned reboot crossing over with the original critically acclaim series.
 * Hoisted by His Own Petard: Silico hadn't thought about finding a way to keep him from being wiped out from existence.
 * I Resemble That Remark: Blossom denies the fact that she's uptight and a neatfreak.
 * In the Style of...: The finale uses the 1998 series' opening title card and uses the end credits theme.

 * 1998!Buttercup believes that the 2016 Powerpuffs could be imposters that could put them in jail.

 * Not So Similar: Between the 1998 and 2016 incarnations.
 * O.O.C. is Serious Business: 1998!Buttercup calls out the 2016!Powerpuff Girls, in which is supposed to be 1998!Blossom's job to call out people.
 * Oh, Crap!: Silico gets this as he finds out he's fading from existence.
 * Parting Words Regret: 1998!Buttercup calls out the 2016 counterparts as "inferiors". At the end, 2016!Bubbles as she's the only one remaining, saying she wished they were like them.

 * Self-Deprecation: Meta-humor on the 2016 reboot's overwhelmed dislike is put to good use in the finale.
 * The narrator brags about how long he was gone since the second season.
 * After Reboot!Bubbles shouts at '98!Bubbles that her voice is annoying, '98!Bubbles is creeped out by her expression, referencing the facial expressions used throughout the reboot.

 * The End... Or is It?/Happy Ending Override: At the very end after defeating Silico, the 1998!Powerpuff Girls eye their villains awakening from unconsciousness. They get ready to fight them again. Fortunately, the finale led to giving the original series a revival.
 * "The Reason You Suck" Speech: After the 2016!Powerpuffs took on 1998!Princess Morbucks alone without the 1998!Powerpuffs along with them, they're displeased for not having them along to help. Followed by Buttercup calling them out for how they differ from her and her sisters.
