Hephaestus

He is made by Nicholas the human fox AKA Human-fox Studio on YouTube.

The Decoy:
Hephaestus' Decoy form, looks Just Mario, but without the red "M" on his emblem on his hat and with messy and unkempt hair with a messy and unkempt mustache to match. His eyes also have dark shadows around them, and are bloodshot as if he hasn't slept in days/weeks/months.

He also has a huge grin with a black void in his mouth and pitch black gums that are invisible, only showing his slightly yellowed teeth.

The Halfway Point:
He doesn't use this second form very often. But when he does, he looks like a slightly taller Mario with burn marks on his body (mostly his legs, torso, and arms) and darker colors. His hair is also more messy and his mustache looks slightly burned off.

His ears are more pointy, his face is more disfigured and menacing with his teeth now small and sharp with a slight pale reddish orange tint. The emblem on his hat also has got cracks in it. He can also make his hands be covered in fire, but that's an ability and is optional

Half of his mouth is melted, the bottom of his left eye socket is drooped downwards to mimic the melted flesh of Mario's corpse, and his eyes are smaller and more orange with a yellow gradient in the middle. His clothes (except for the gloves and shoes) are more wrinkled and torn, revealing more of the burnt flesh.

THE GOD OF FIRE
His most used, and favorite form. Hephaestus' third form is similar to his second form (the halfway point) But a lot taller and more menacing. His flesh now fully representing what he did to the red plumber, but with some differences in the face to fit his desired looks. His face resembles a human skull, but with small and thin lips to seem more cartoon-like for the uncanny feel. His hat also melted into his head.

His eye sockets are more expanded and his sharp teeth are longer and more reddish orange. Half of the flesh on the left side of his head looks like it's melting away, but it just looks like that. The left side of his head also reveals a fake skull to more mimic the look of melted flesh, and there are also flames coming out of it, and that's because his fire breath is hidden in the back of his head and these flames act like a representation of his fire powers.

He can also make his hands fiery, but it's still optional because it's an ability.

Abilities

 * Fireballs.
 * Shape-shifting.
 * Invincibility.
 * Fire breathing.
 * Fire blat from his hands.
 * Can make his hands covered in fire to show his powers (completely optional).

 * Power-up collection (can use the abilities from various power-ups from the Mario universe, except for the super leaf and the tanuki suit).

Weaknesses

 * The ice flower (will temporarily freeze his body in a giant ice crystal, puts out his flames and makes him slower and weaker, the ice will eventually melt around him and his flames come back.)

Biography
Instead of this dumb ZALGO stuff, his origin story is WAY different.

Before he was known as Hephaestus, Diamorfotisavros was a T. rex/dinosaur like creature with red scales, the horns of a bull, the mouth of an alligator, the feet of a lion, the claws of an eagle, the tail structure of a fox (if foxes where 15-20 feet tall), the body of an Apatosaurus, half of a body of a T. rex, 4 arms (two being reptilian like human arms), and orange eyes.

After seeing humanity evolve, as well as technology, and found it as an opportunity to take over the world. He gained the power to exist in both the real world, the game world, and in the Mario universe, and has even combined the game world and Mario universe together.

Mario was just relaxing at his home before hearing some strange noises from outside, finding red footsteps into the pipe to the mushroom kingdom.

Mario soon found the source of the noises in a cave with a stone bridge going over lava, that being Diamorfotisavros. Diamorfotisavros was attacked by Mario... but the famous red plumber's attacks were in vain. Diamorfotisavros breathed fire all over Mario, turning him into a corpse with melted red flesh.

Diamorfotisavros soon consumed the red hero, and swallowing him whole, giving him the abilities and information of his life, and some forms to shape-shift into and alter to fit his demented needs. He then became "Hephaestus".

Trivia

 * Hephaestus’ name is based off the Greek god of fire who goes by the same name because... well fire... and god stuff...
 * Hephaestus' real name (Diamorfotisavros) is a combination of the Greek words for shape-shifter (diamorfotís) and dinosaur (deinósavros).
 * The original concept version of Hephaestus' design was just a sloppy edit of SkellyMakesArt's Heraclitus redesign, Mario.EXE from Mario Madness, and the victim #1 image disfigured with the liquify tool plugin in paint.net to make a skull... it was just a concept though.
 * His clothes are not actually his clothes. Since Hephaestus can change between forms, his "clothes" go back to normal like they weren't torn and his hat returns, and that's because they are made of his flesh with the intent to look, and feel like clothes. Yes, Hephaestus is nude all 24/7.
