You know, I gotta say, whenever you talk about this game, you're really "In your element."

You overlooked something about the Genasi: According to the Elemental Evil Player's Companion, Genasi can be formed through magical experimentation with the Elemental magics, gone wrong. So you can just be a Wizard who was practicing an improved Conjure Elemental spell, and then you accidentally, blast yourself in the face with pure energy from the Plane of Air, becoming an Air Genasi.

"...Well, gargoyles were originally created to scare and ward off evil spirits... so I suppose they accomplish what they were intended for..."

scrawls in notes Esper; Evil, possibility is likely.

Imprisonment. It's a ninth level Spell. That's how players put genies in bottles.

Long ago, the four nations lived together in harmony...

Fun house rule gargoyles have an aura causing undead to struggle to get get close to them, take less damage from undead, and deal more damage to them

I would’ve thought that Gargoyles would be constructs

The Elder Elementals
The fearsome Leviathan
The magnificent Phoenix
The dreadful Tempest



And finally, Derp Turtle

I really thought you were going to say that Gargoyles should be Constructs, rather than Elementals. I've never considered them being Monstrosities or Fiends.

"Genasi can make it in most animes"

Insert Berserk

Now I wanna see an elder elemental fighting a tarrasque.

Probably not gonna survive the encounter but it would look cool until I get crush by a flying reptile.

Ah Elementals the purest form of "Nature is pissed!" also with those genies what did I say before about humanity's greatest power in fantasy? Genasi are further proof.

I’ve always interpreted the “hold their breath” rule to be based off them getting the chance to take a breath. A sudden surprise choking/drowning would be just the number of turns equal to Con Mod

Personally,  my favorite elementals are the ones specially made for a setting, like 2e ravenloft's Grave, Pyre, Blood, and Mist. They still represent the 4 basic elements, but with a simple twist to make them fit into their surroundings better.

No one:
If there was a firenewt bard he could spit fire 2 different ways.

The word Myrmidon always reminds me of Fire Emblem

Gargoyles are construct in my books they are guardians of temple or magical building created by powerful mage

Elementals in general are among my favorite enemies, the regular box elementals are also my favorite among them

When you were listing all those 4th edition mixed elementals, all I could think of was:

The Sash-Ringing, the Trash-Singing, Mash-Flinging, th-th-the Flash-Springing, Ringing, the Cr-Crash-Dinging, daa.

THE HASH-SLINGING SLASHER!

I'm actually homebrewing a Warlock Patron pact of the Genie. Its still a work in progress. But the general idea is a subversion of The Genie serves me, and is now I serve the Genie.
