Gonna do them in order until I run out of steam:
Diffocod: It’s a cod, which obviously makes it a water type, but it also either differs or is difficult. Actually I’m gonna go with Diffocod differ in ways that are difficult to tell. It has a bunch on minor form difference a la Spinda. It’s Water/Psychic I’ve decided. Diffocod possess the mental prowess to immediately recognize all of their minor differences.
Firebermen: Is obviously a Fire type. But also... fibers... and “men” is plural implying that this is one of Falinks-Tandemaus sort of ones that is just straight up multiple creatures treated as a single Pokémon. I’m now imagining tiny men made of fire that are tied together by a fiber... that is also made of fire. Weird concept, hypothetical GameFreak, but okay. It’s a pure Fire type.
Nanarcer: Is, I think, an archer made of bananas? So primary grass (Oh hey we already have a starter trio (no we don’t, Firebermen and Diffocod are definitely single stage Pokémon)) and... I’m feeling Fighting as the secondary type here. Yeah this isn’t a starter either this is the Bounsweet/Smoliv kind of Pokémon, it’s earliest stage is a banana with a face and it gets more humanoid as it evolves.
Exulation: Oh man this one doesn’t give any hints towards what kind of creature it is. I believe it’s a pun on “Exhalation”, so it’s primary characteristic is that it breathes out... I think it’s a Fairy type, and there’s some sort of magical property that occurs every time it breathes, but I really can’t guess what the thing actually looks like.
Sweeze: Another Fairy type. A funny little trickster made out of candy. Bet it’s gonna get a weird signature move that makes it really good in competitive and then we get a ton of memes about how, like. Tyrannitar and Grimmsnarl are scared of Sweeze.
Barbon: Is a fish but actually it’s not a Water-type, it’s Steel/Dark. Wait this is treading really closely to Overqwil in terms of concept, maybe it shouldn’t be a fish? Hmm... maybe the execution will be different enough.
Browbedably: Oh man what a name. But it’s a portmanteau of “Browbeat” and “Dabble”, so this is like, a really overbearing artist? I’m now imagining it as as a sort of jerk version of Smeargle, so I think it’s another breed of dog and is a Dark type.
Strisitor: Portmanteau of stride and visitor. This is definitely a mid-stage one. It’s first and third forms have more descriptive puns involving the word stride, and so it needs to incorporate the same word and so we get “Strisitor”. It’s a bird, but a bird that prefers to run so I don’t know if it should be a Flying type. You know what maybe Strisitor is a pure Normal type, but I think it’s evolved form is going to add something to it that gives it a secondary type.
Wishine: Is a shiny coin that evolves into a wishing well. Or maybe they aren’t literally a coin and a well, but they have those motifs. In fact, they’re actually fish. Yes this is the third fish line in this post but in my defense there really are a lot of fish Pokémon. Wishine is pure Water type.
Quartwish: Wait I actually hadn’t read this one when I wrote Wishine’s description, is this Wishine’s evolved form? Okay. Quart in this context is a unit of volume, a reference to quarters, and a reference to quartz, because Quartwish is a Water/Rock type. Quartwish carries a basin filled with water and Wishines wherever it goes.
Prinvaully: Is a portmanteau of prince and volley. This Pokémon has a regal motif and throws things. It’s not the fully evolved form, because that ones name is gonna be a pun on “King”. Prinvaully is... a Steel type, not really based on an animal. It’s got a crown but the crown is actually a part of it’s body and similarly shaped spikes grow on the rest of the body and get used as ammunition instead.
Trifies: Huh. Trifies, Trifies, Trifies... There’s a specific vibe to this name, but it’s really hard to figure out what words it might be playing on. Maybe “trifle” but that doesn’t tell me much. ... I think it’s a Fairy type, and I think it isn’t fully evolved and I... can’t tell you much more.
Sumentfurtific: Umm... does this one even fit in the character limit? No it doesn’t it’s 14 characters long. Illegal Pokémon name. Anyway. Sumentfurtific is ground. Like not just that’s it’s type, Sumentfurtific is literally just a soil layer. I uhh... don’t know what it looks like when you send it out onto the battlefield. Sumentfurtific is not allowed to exist, so it doesn’t need to make sense.
Apporins: This Pokémon’s entire reason for existing is a stupid pun on the phrase “comparing apples and oranges”, and to be clear, that is a compliment. This a third branch of the Applin family, where the wyrm starts inhabiting an orange instead so that it can know what it’s like and my god that is stupid but that’s what Apporins is and you know what this might be my favourite on this list GameFreak please turn Apporins into a real thing. It isn’t even a different type from Applin’s other evolutions, this is just straight up a third Grass/Dragon final form of the same family.
Powean: ... I think this one is Prinvaully’s evolution. It’s a pun on “queen”, not “king” like I thought it would be. Yeah I guess “prince” and “princess” both start with “prin”. My bad. Still pure steel type. It grows even more menacing spikes and an even more impressive crown.
Founty: It found you and now is ready to collect you’re bounty, heh. This one is just a sendup to westerns in terms of it’s personality, which is pretty funny. It’s a Dark type, due to the grey morality of the archetype its aping. This one is based on an animal, but it’s gonna be something entirely unrelated to westerns that the designer just thought would look cool.
Sankle: Water/Ground. Quicksand Pokémon. It is a pit, that you sank into, up to you’re ankle.
Aerocioundly: Was worried this was another Sumentfurtific situation, but no it’s 12 characters that’s allowed. Crisis averted. So obviously this is a Flying type. In fact I think a pure Flying type. Windy thing.
Derphitiges: Oh that is a weird name. It’s Bug/Rock. It’s like a termite but it eats rocks instead of wood.
Aunces: It’s, uh... Yeah I’m out of ideas. How many did I get... 19? Okay.
