*Sigh* you're all bastards.
Also Chiro is
clearly the rival. A weird one who gets the weak starter and joins Team Abyssal, but still.
PkMn Trainer Chiro / Abyssal Admin Invidia (Victory Road)
Swoobat (Psychic/Flying, Unaware)
Air Slash
Assurance
Psychic Fangs
Nasty Plot
Rival Invidia's speedy lead and special attacker. Not optimized by any means, but if you let her set up, she's going to obliterate you with +4 Air Slashes.
Crobat (Poison/Flying, Inner Focus)
Cross Poison
Venoshock
Air Cutter
Toxic
Yeah she's got the two basic bats what do you expect. While Swoobat can sweep your team, Crobat's just here to cause problems on purpose and be a really on the nose metaphor for toxic self-talk.
Mimikyu (Ghost/Fairy, Disguise)
Mimic
Copycat
Shadow Claw
Curse
The embodiment of Invidia's mimic powers and also probably the thing that gave the most trouble in earlier battles, being a surprisingly good tank (unless you know how Disguise works then she'll basically defeat herself). In Postgame battles she swaps Curse for Play Rough and becomes even more of a nightmare.
Zoroark (Dark, Illusion)
Taunt
Copycat
Sucker Punch
Night Daze
I'm gonna be real I just gave this one thematic moves. Two of them egg moves, even. Haha, egg moves. Still an annoying technical fighter.
Sylveon (Fairy, Cute Charm)
Disarming Voice
Draining Kiss
Light Screen
Alluring Voice
Abyssal Boss Superbia hates this one. He only tolerates it because for some reason she's the one with vampire- and sonic-themed moves. And a weird glitch where Cute Charm's gender effect is reversed. Weird that. Also tended to lead with this one in earlier Double Battles with Admin Avaritia so they could do that annoying double screens bullshit.
Decidueye (Grass/Ghost, Overgrow) [Starter]
Spirit Shackle
Leaf Blade
Sucker Punch
Brave Bird
Gamefreak cheated and gave her Brave Bird about ten levels early, but the poor, maligned starter is back for revenge. No, not in the buffed Hisuian format. She's still a ghost/ambush attacker. Just gives her more to prove, especially against that stupid gorgeous Delphox the other trainer got.
Alright, alright, maybe not quite as balanced as a normal rival team, but I think it works. Notable weaknesses to Fire and Steel, which sounds about right.
