Funny enough, if you show Landorus to Peony he comments about this.
I just found out about this earlier and I love Peony so much
Articuno (Normal): Whoa! It's our imposter ARticuno, only without that dodgy mask! Bet you it gets a lot mroe fans with those sharp, bright eyes out in the open, eh? Hang on, though--has it gotten chilly in here? Did a blizzard blow in or somethin'?
Moltres (Normal): Whoa! Now those are some serious flames! Hey, imposter Moltres! Have you got a fever or somethin'? You get some rest, hear me? Take care of yourself
Mewtwo: Aha! That's Mewtwo, the ferocious Pokemon created through genetic manipulation, isn't it? Its face is a bit on the pale side...Seems docile for the most part, though! It might not have the friendliest-lookin' mug, but I'll bet you it's a decent sort on the inside!
Suicune: Wow! That's a beutiful Pokemon, that is! Is that Suicune? It's dead cool how that horn thing on its head sort of makes a loop! I wonder, though...How's it supposed to roll over when it wants to sleep on the other side? I bet it's got a rought time sleepin' in general. You all right, Suicune? Gettin' your eight hours?
Azelf: Azelf, eh? The Pokemon that gives people the willpower to get through sticky situations? Maybe if I had one of these around, I'd be better at draggin' myself out of bed or cleanin' up around the house! Sounds like every home needs an Azelf! I've got to catch myself one!
Dialga: So this is Dialga? The Pokemon that controls time? Well, if that's not just talk...think it could give me a cheeky rewind whenever I make my darlin' Nia mad? That aside...has this thing got a bangin' cry or what?!
Reshiram: Whoa! Is that Pokemon's tail on fire?! Wait--come again? They say this Pokemon could scorch the world? Well, don't you look calm for someone carryin' around a potent Pokemon like that, Chief? That takes backbone, that does! Just watch out you don't get burned!
Tapu Lele: Who's this rockin' the perm, hief? Friend of yours? What? It's Tapu Lele, a Land Spirit Pokemon that's the guardian deity of some island?! Hm! Sneakin' in a bit of undercover travel, is it? Bit small for that, though. Bet its papa's worried! Guess its family believes in lettin' its little ones find their own way...
Tapu Fini: Who's this rockin' the eyelashes, Chief? Friend of yours? Oh, it's Tapu Fini, a Land Spirit Pokemon that's the guardian deity of some island?! Hm! Sneakin' in a bit of undercover travel, is it? Hang on... Is it me, or is there loads more moisture in the air all of a sudden? My throat's feelin' great now! Cheers, Tapu Fini! They out to make you the guardian deity of humidifyin' too!
Nihilego: Nihilego, eh? The Parasite POkemon? Whoa! Looks soft and floaty as a dream! Just think how cozy you'd be, havin' one to rest your head on like a pillow! Y'know, Chief, you did take that lovely pillow I found before... Come on-- let me have Nihilego wrap nice and gentle around my noggin for a bit! It's only fair. [Father Beast Peony.........]
Perhomosa: Pheromosa, eh? The Lissome Pokemon? Seems ultra-mega-refined! That's a Pokemon with class! Please to make your acquaintance, Pheromosa! What do you say to a handshake? ... ... ... ... ... ... That...might've been the coldest shoulder I've ever got. Did I do somethin' wrong, Chief?
Guzzlord: Guzzlord, the Junkivore Pokemon? Couldn't have named it better. Look at it go, chowin' down on that rubbish! Good for you, you great gourmand! No one could call you a fussy eater! Chief, if you've ever got some rubbish you can't be bothered to bin, toss that one a treat!
Stakataka: The Rampart Pokemon, Stakataka! That's one mysterious life-form, all right! Look how many likttle blocks make up this one Pokemon. They're just the right size for a pillow too, eh? Wonder if it'd let me have one... Oops! Guess not! Fair enough--losin' part of your body's no fun! Come to think of it... How many blocks would it have to lose to not be a Stakataka anymore?
Solgaleo: It's Solgaleo, the Sunne Pokemon! It practically roars "sun," doesn't it? Can it reall make the darkest of nights light up like midday? That's pretty cheeky! Sounds like it'd be a great help on those nights you just don't want ot head home yet, though! Eh? It comes from anotehr world, too?! That's one fired-up Pokemon!
Raikou: So this is Raikou, the Pokemon they say descended with a bolt of lightnin'? That must've been a pretty rough ride, eh, mate? No wonder the mane on your back's gone all curly.
Buzzwole: Gahaha! Just look at the muscles on Buzzwole! That's one Swollen Pokemon, all right! I don't mind sayin' I'm stronger than most, but I've got to bow down to your brawn, mate! You and me, Buzzwole--we ought to go get a few reps in sometime! I'll spot you!
Poipole: So this Poipoke's a Poison Pin Pokemon that came from another world? Guess it's got a bit of an unusual face, but it doesn't look that different from the type of thing I could find in tall grass around here...Gwaaah! Did those needles on its noggin just spray out poison?! Whatever world it came from must be wild!
Celesteela: Gwaaah! That thing's MASSIVE! Whoops...sorry to shout. Got a bit carried away from the shock! That's Celesteela, the Launch Pokemon, eh? And it flies around superfast by firin' flammable gas from those arms? I can't think of more to say about that than...absolutely wicked! Gotta say though, Chief...the odd ones sure seem to take a shine to you, don't they?
It's a shame he only checks pokemon from the Adventures, though. I want you to make small talk about Cosmog and the wolves, please
