Pokedex [Hattrem]: "The moment this Pokémon finds someone who's emitting strong emotions, it will pummel them senseless with its braids to silence them."

One feeds on negative emotions (Impidimp). The other [b][i]silences[/i][/b] them. 

Maybe it's actually done to starve the Impidimp o.o

[s]EDIT: Also goes without saying, but I can think of at least two characters who may be cooked the moment they meet a Hattrem XD[/s]

Wait. WAIT. IT'S A SPECTRUM! We have the Pokemon Emotional Spectrum!!! XD

Ralts: Drawn to positive emotions [s]and puppeting one sad boi (Ralts-atoullie style) to see more of his happy thoughts of old[/s]

Hatenna: Walking vibe check [s]Hatenna PoV (You Failed The Vibe Check): "BEGONE, SOURCE OF BAD THOUGHTS! TO THE AFTERLIFE WITH YE!"[/s] 

Impidimp: Feeds on negative emotions like a true internet troll of yore [s]"Lol. Kek even." *goes off to ragebait the general public and confuse the media so he may FEAST upon their salty tears and negative emotions....literally*[/s]

EDIT: I just had an epiphany....these Pokemon could be aligned to different Latern Corps rings from DC. Ralts is the blue ring (hope), Impidimp is yellow (fear), and Hatenna is red (anger/rage). Maybe? Maybe. :O
