Just to clear something up. Blissey was used as an example of a Pokemon whose DESIGN embodies a specific stat. I am aware that it doesn't have 1 in any stats. This is a design challenge , not an attempt to make Pokemon that work in battle. Although feel free to come up with scenarios where they do work in battle. I simply thought the title sounded super cool, so I made sure to not clickbait you and actually give them, effectively, only 1 usable stat. Hope you enjoyed regardless. NEXT WEEK'S VIDEO IS CRAAAAZY!

The fact that you didn´t make a LITERAL glass cannon as the special attacker makes me a little sad

“I can’t do a Cheetah for Speed because it can’t have any Attack or HP”
little did Ron know he just perfectly described a Cheetah

Only problem is that seahorses are COMICALLY slow, due to only having a single fin. I think the lightning bolt design makes up for it, though. My favorite's Spekrill

I think Special Defense made an animal is a cockroach. Poor attack, squishable... And yet can survive a nuclear apocalypse.

12:02 "so i took inspiration from a sea horse!" Ironically one of the slowest animals lol

You'd have to be either a master strategist / a maniac or both to effectively use these Pokémon.
Wonderful dude.

5:22 a sturdy pokemon with 1HP... we're doomed

I love how all of these are designed un a way that they actually offer some kind of offensive capability: Both the offensive embodiments have access to broken priority abilities to deal with their low speed, Grafense has 1hp and sturdy and can sweep with body press (assuming it learns it) and Speedra is just a super annoying status spreader. And Specialotl is, well, IMMUNE TO ALL SPECIAL MOVES

i honestly think that a LITERAL glass cannon would be AWESOME for the special attack
like, a immobile pistol shrimp that is mostly made of glass frigile that moves slowly due to the massive cannon (maybe a regional varient of clawncher?) and fires off massive beams of energy from it's cannon

1:11 an ant holding a gun

You KNOW there would be one random early game trainer with one of each of these to teach trainers what each stat is for.

Another way to do special defense would be "magic circles on paper of delicate wings."  The circles neutralize beams and bolts, but you can just tear through them.

Average gen 10 spread:
Also I just realized tardigrades are pretty much the living embodiment of this idea, mainly with special defense. I’m pretty sure you’ve made a tardigrade inspired design in the past so it’s probably better to bring variety but it’s a fun thought.

One cool concept I noticed is that most, except attack fakemon, are pretty much aquatic-themed creatures. What if the HP fakemon possesses a symbiotic relationship or even a predator-prey relationship to the other smaller fakemons. Since the HP fakemon have abysmally low offensive stats, it would not technically harm the smaller fakemons upon consumption, but it will consume them for the sake of benefitting from them, and in return the smaller fakemons will have a host to live in.

The gimmick can revolve around the HP fakemon gaining either the ability or the stats (or maybe both) of the consumed smaller fakemons and maybe harboring some small physical traits of the consumed fakemon.

It's a similar mechanic to what Dondozo and Tatsugiri have.

8:47 bro, A MIRRORRRR

Speedra: “Speed. I. Am. Speed.”

As others have said, 1 base HP doesn't cause the pokemon to be like shedinja. It just makes the pokemon have an incredibly low base HP.  Shedinja is hard coded to have 1 HP.

True green: thankfully there's already a perfect fictional trope to use for our tiny but powerful psychic pokemon...

Me: oh yeah! A glass can...

True green: the mystical fetus.

highly defensive pokemon with 1 hp is pretty useless
