I'm Really Digging The Whole Possession/fusion Concept. Any Other Little Headcanons For It?

I'm really digging the whole possession/fusion concept. Any other little headcanons for it?

I’m so sorry this took so long, Anon, but yes, I do!

Giovanni

Inspiration: Carrie (Carrie 2014) / Ultron (Avengers: Age of Ultron)

Pronouns: I / They / Them

His eyes have gained a layer of tapetum lucidum - colloquially known as “that weird membrane that makes your cat and dog’s eyes glow when you shine a light on them.”

Can detect people’s auras, in a way. Not so much as to where people are, specifically, but as to tell if there’s any sort of malicious intent towards them.

Under severe stress, they can instinctively teleport out of danger’s way, but it’d drain them quite a bit.

Maxie

Inspiration: Godzilla (Godzilla franchise)

Pronouns: I / He / Him

The first time he tried fusion, he had a… particularly weak stomach. That’s when one of the grunts found him, but when they tried to give him a bag of ice to cool him down, the ice went liquid in about half a minute.

When under severe stress or nervousness, he has a tendency to melt things when he touches them. This ends up melting his paperwork, which makes him more stressed. He also tends to freeze on the spot with a rock casing around his feet.

His blood has gained a sort of shiny-orange, iridescent quality to it, like magma. It dulls when he drinks a lot of water, and even starts to glow when he’s pretty pissed.

Archie

Inspiration: Lapis Lazuli (Steven Universe) / The Asset (The Shape of Water)

Pronouns: We / They / Them

Due to his body being fused with Kyogre, and his body temperature adjusting to water accordingly, he can survive pretty cold temperatures. He could swim in the Arctic Circle in his wetsuit for a couple minutes before it starts to bother him.

The lines on his body tend to glow and pulse in response to certain stimuli and emotions. Other signal-based water type Pokémon, like Lumineon, Starmie, and Lanturn, seemingly understand these signs (and he can understand them. Not specifically, but he can grasp a general idea.)

Always nearby some source of water, whether it big or small - the others are not pleased by Archie’s new habit to sit in a full bathtub for an hour or more.

Cyrus

Inspiration: Enchantress (Suicide Squad)

Pronouns: I / They / Them

Sometimes, if no one engages with him for a while, his eyes go black. When he speaks, it makes no sense - spoken cryptically as an ancient language. (”Ay, yo, Cy, you ok?” // “H̵̫̙̔̀ḛ̷̠͈̚t̴̩̑̈́̐͛ ̸̨̨̱͔͊n̴̺͇͚͓̓ë̵͉́̅̿̚s̸͈̱̠̳̎́̀k̵͔̀̒a̶̢̙̝̥͒̉͛͘ȓ̷̰̾d̷̗̠͉̦̐s̵̤̗͙͒ ̴̜̉m̷̡͙̀o̷̦̻̮͖̔̓́c̴͔̙͍̾͊e̸̦̔̋̓h̸̰̩̅t̴͙̼̪̐̀̕.”̵̺̤̠̘̀͂ // “Oooohkay, buddy, let’s go for a quick walk, yeah? Walk n’ talk.”)

Will sometimes stare off into space above for hours on end. No one knows why, but no one really wants to try and bother him at that time.

Is utterly silent when he moves. No one knows if he’s in the room until he’s right behind them. ( [Warping the wall and stepping in from the shadows] “What’s going on in here.” // “AAAAAAAAHHHHHHHH” )

Ghetsis

Inspiration: Venom Symbiote (Venom)

Pronouns: We / They / Them

Taking into account all the extra features involved, he’s the tallest fusion, with Lysandre coming in close as second.

Despite him not needing the cane to walk, technically, they do need ice to maintain the fusion (it acts like an adhesive, in a sense, preserving Kyurem from Ghetsis’ body heat, and keeping Ghetsis cooled enough to deal with Kyurem’s chill).

Coming off of that, they’re highly heat sensitive - they try to shy away from Maxie if possible, due to warmth melting the adhesive and making it easier to unfuse.

Lysandre

Inspiration: Smaug (The Hobbit series) / Rodan (Godzilla franchise)

Pronouns: We / He / Him

Surprisingly doesn’t need to eat to survive while fused. Not out of any biological change, but because of Yveltal’s influence - the life they drain from other people sustains them just fine.

As for his ability to drain life - he can’t really ‘turn it off’ in the broad sense, but he can actively avoid draining life from a specific person if they concentrate.

He can produce wings and is capable of flight, but he can’t fly too far or for too long.

Guzma

Inspiration: Spider-Man (Avengers: Civil Wars / Into the Spiderverse)

Pronouns: I / They / Them

His chest glows with a white light that outlines the dark bones of his ribcage. It was so bright and so unnatural that he couldn’t sleep for the first few nights. They can also reflect light in a way that turns them invisible temporarily.

He’s oddly developed a bit of a hunger for fruit. As someone who is technically both a bat and a human (who had lived on a strict diet of various cups of hot chocolate, potato chips, and candy bars), the switch is a healthy - if not jarring - one.

Likes to crawl on the ceilings or stay in high places to the point he fell asleep on the walls. Trying to get him down was a challenge at first. You know that scene in Into the Spiderverse where Miles is stuck to the lights and needs to unstick? Kinda like that.

Aaaaaaand, bonus!

Sycamore + Xerneas

Inspiration: Mothra (Godzilla franchise)

Pronouns: We / They / Them

Life and renewal seems to spring up where they walk: flowers bloom in the grass, cracked tile becomes whole, tired beings gain a pep in their step.

Possibly the only person who can touch Lysandre while he’s fused with Yveltal without getting drained. Xerneas’s powers help cancel the other’s out, and vice versa.

They can form powerful moonblasts in response to danger, but they’re more often then not a curious pascifist.

Sometimes just sit out in nature and feel the grass. The mere presence of other living beings is a comfort to them.

They can heal others through sympathetic touch and concentration. If worse comes to shove, they can transfer some of their own essence into others.

Sycamore would be VERY averse and confused to fusion at first glance, and Xerneas chafes as well. It takes them a while before they really settle into each other, and end up being a pretty stable fusion.

His eyes have gone blue, with X-shaped pupils. A crown of antlers pokes out from the sides and behind his head, and blue lines run down the bridge of his nose and cheeks. If they’re very excited, a tail may or may not start wagging.
