Multi Dimension Nonsense

Incredibly self-indulgent crossover au where a lot of my favorite blorbos live in one shared world, in the PMD universe. This whole blog is just to be fun and cringey, don’t take it too seriously. - this blog will be filled out more later, still under construction

What is the PMDN AU?

PMDN is a large crossover where characters from multiple series I like take place within the same world. The world is a PMD-based world, where everyone is pokemon. That said, it is also made to be more similar to our world structure wise rather than fully Pokemon Mystery Dungeon.

The plot lines of stories within this universe are usually similar to their canon counterparts, at least as much as they can be with universe change. There are some exceptions, where there might be changes to be better suited for this universe, for crossovers, or to follow pre-existing AUs I have for the respective series rather than canon. Also for some media I just don’t like the canon so rewrote parts I didn’t like.

Each series has it’s own PMDN tag, and that tag will be used for every post including it’s characters.

What series are part of the PMDN AU?

Series list is here. This post will link to each series’ PMDN story summary post when created. Please note I will be posting untagged spoilers for all these series.

What is PMDN’s lore?

A masterpost of all lore posts is here. It will be updated as posts are made, and also includes some topics that will be written up later. You can also check the #lore post tag.

May I make fanart/fanfic/etc for PMDN?

I would be very honored if you did so! I know there isn’t much to go off on the blog quite yet, so if you have any questions about specific universes and changes, let me know!

Can I make my own PMDN?

Of course! PMDN is ultimately just the concept of multiple series within one PMD AU, and that concept is so general it’d feel wrong to say you can’t. In fact, if you’d like to make a PMDN, I’d love to hear about it!

My friend Connor who helps with this blog also has their own version of PMDN called PMDN Legends, and their blog for it can be found here: @pmdn-legends

Asks are on feel free to ask me stuff if you have any questions! I am very bad at actually figuring out how to lay out and explain the lore, so being given asks about particular things is very nice.

This blog and AU is still under construction. More will be added to this post as more is figured out! Thank you for coming by.

also some eito paneling practice 😁

[pmdn-au]

also some various ranmaru and sara sillies

[pmdn-au]

various silly doodle with these guys…

did decide ultimately final route for pmdn will be second scenario slightly to the left, with goodbye eito also occurring and leaving him and nozomi as the only survivors of the SDU. also eva lives because she deserves to.

I decided Smiling Critters exist in PMDN as just like a normal toyline/this universe’s version of Care Bears so decided to make a hypothetical plush timeline for them

other notes:

- Gen I did not have a full tie-in TV show but did have a few TV specials

- While there is no evil gas or orphan experiments in this universe, Catnap was still removed from Generations 3 and 4 due to his perfume plush being contaminated (by something else not evil gas) and recalled. He was added back in Gen 5 and it was a big thing.

- Gen 2 DVD sets were definitely also scented like the 2003 Strawberry Shortcake ones

- None look like the canon plush purely because I think the canon plush kinda lean to heavily into looking creepy due to being from a horror game - that’s just my own personal preference though :)

- I am not really a plush or toy expert so these are all kinda designed with minimal research, unsure how fully realistic they are

time for the incinerator :)

Birthday Rhyme Time!!!

[pmdn-au]

bonus dance gifs! I actually slowed them down a bit for the video

[pmdn-au]

finished a thing with the guys!!

[pmdn-au]

some soul lore (particularly regarding the ‘splitting’ of souls)

shadow and light are not necessarily the ‘evil’ and ‘good’ someone has - they are simply what souls are made up of.

(also as an elaboration - Xion and Roxas actually both ended up with souls purely of shadow unlike how this diagram shows. it couldn’t really fit on this simplistic chart, but while a soul is split there is a high chance of corruption that may lead to imbalance. basically all of their light was corrupted into shadow during the split. this is how they are both Shades.)

More FNAF refs! This time Elizabeth + various Michaels

Elizabeth: Buneary

Michael: Nidorino/Eevee (Teen + Adult) -> Nidoking/Shuckeon (Post-Scooping)

[pmdn-au]

Some FNAF guys cause finally tackling the monster that is designing all these guys… expect more of them to come.

In order:

Charlie (Charlotte) Emily - Teddiursa/Pancham

William Afton - Nidoking/Chanceon

Evan Afton (Crying Child) - Buneary/Eevee

Am going with Evan for Crying Child cause while I know there are arguments for Dave and Adam, I’m just used to the Evan name for him ¯\_(ツ)_/¯

[pmdn-au]

very small emoji dump cause has been in my drafts for a while and i have no clue when there will be more

Regional Forms

Regions such as Galar or Paldea do not exist in PMDN, so regional forms go by different names and come from different areas. Regional forms have the typical “place”-an names, but are more typically referred to as their new main type and species (ie, Alolan Vulpix is Ice Vulpix, Paldean Wooper is Ground Wooper, and Alolan Exeggcutor is Dragon Exeggcutor).

Paldean and Galarian Forms are native to the Yrex Continent. They are referred to as Yrexian.

Alolan Forms are native to the Quaza Islands. They are referred to as Quazian.

Hisuian Forms are native to the Garde Continent. They are referred to as Gardean. Hisui Forms are slightly uncommon, but still exist and are not extinct in this universe.

There are currently no forms native to the Tina Continent.

Friendship / Happiness Evolutions

One way that Pokemon evolve is via Happiness / Friendship. As a note, both Happiness or Friendship induce evolution in this case.

The evolutions are typically triggered by a large act of love, trust, or faith by them or a loved one. Alternatively, via an event that causes the pokemon to feel intense joy. This is not the only way for these evolutions to occur however - even small acts of friendship or joy can induce said evolution, particularly if they are happy or have close loved ones over a prolonged period of time. A pokemon’s general happiness can usually be read by examining their footprint. Alternatively, it can also be determined by reading their aura.

Some items have effects on friendships and their evolutions. Wearing a Soothe Bell is said to help soothe a pokemon leading them to be generally happier in their day to day life. Gummis, Pokepuffs, and Pokebeans are said to all have large effects on a Pokemon’s happiness, but research is unclear. It seems the amount of joy they cause is simply tied to the combination of their great taste and the joy of the fact that they are often given as gifts.

Despite the fact that typical Gummis have no clear beneficial effect on inducing evolution, there has been one in particular that has been developed for this purpose - the Wonder Gummi. The Wonder Gummi was developed by scientists during the Crown Decade and is both expensive and controversial. By eating a Wonder Gummi, evolution via Friendship/Happiness can be artificially induced.

The opinions of this invention are highly mixed. Many pokemon consider it unnatural - and that it encourages pokemon to not create close bonds. Many others believe that it is important to allow pokemon to evolve whenever they like without external factors. Many highly criticize its high price.

Many believe it is unhealthy - thoughts that are not unfounded due to the use of Wonder Gummis being linked to half-evolution along with lowered battle capabilities. Others argue that regardless of effects, pokemon are free to choose what they desire as long as they are aware of the risks. It is also heavily argued as something that makes evolution more accessible for shadow pokemon and pokemon with depression, anxiety, and/or other mental health issues (though obviously these pokemon can still evolve without the use of wonder gummis).
