Eternatus (GTG)

"I shall personally enjoy making you and the rest of this annoying planet suffer."

- Eternatus to Gloria Eternatus is the overall main antagonist of the Pokémon fan fiction Gloria The Glaceon and its sequels.

Appearance
Eternatus is a gigantic, draconic alien Pokémon. Its body has a vaguely draconic shape and a skeletal appearance, and is largely dark violet with red highlights. Its main body and tail are long, thin, and resemble a spinal column, and it has four small, thin limbs ending in claws formed from spindly appendages attached at right angles. Its torso is formed from a cage of appendages resembling ribs, and inside is a glowing pink core that serves as Eternatus's energy source, absorbing energy to sustain it. The core can also project its absorbed energy into massive blasts. Its head is triangular in shape and has a pair of white, eye-like markings in the form of three connected circles, as well as a spindly lower jaw with several diamond-shaped teeth. Over its head is a translucent red film held between five long spikes extending toward its body's rear. It also has a pair of thin tendrils extending from its back, formed from numerous triangular segments. Eternatus's gigantic size makes it the tallest known Pokémon to ever exist.

When Eternatus uses its signature move Eternabeam, it will briefly enter its Eternamax form, becoming far larger in size. In this form, Eternatus's shape drastically changes. Its body becomes incredibly long and serpentine with most of its body forming a massive coil. Its entire body glows red in this form, and present at regular intervals across its length are black rings with spikes extending outward. Its back tendrils now curl around its main body. Its energy core rests at the center of the coil inside a cage of violet spikes. Eternatus's head takes on the form of a giant hand, with its fingers covered in black armor with spikes extending from the back of each segment. At the tip of each finger is a glowing pink eye.

Personality
"Your contentment bores me."

- Eternatus to Alvin

Eternatus is an evil and destructive Pokémon whose goal is to rule the Pokémon universe and have chaos reign supreme. It is also very manipulative, allowing it to easily make allies, only to betray them later. To make matters worse, Eternatus doesn't even have a sense of honor nor redeeming qualities, and instead has a dark sense of sarcastic humor. Also, because Eternatus is nigh equal to Arceus in power and strength, it tends to underestimate its opponents.

Voice
Eternatus has a masculine voice with a demonic undertone. It also often refers to itself in first person (obviously).

History
"Eternatus: This whole universe is mine! Arceus: Not if me and my children have anything to say about that! Eternatus: You four are nothing compared to me! I will bathe the stars in your blood."

- Eternatus battling Arceus and the Creation Trio.

At the beginning of time itself, the first being in the Pokémon universe, the Original One, was born. In order to bring life and stability to the Pokémon universe, The Original One created Arceus and Eternatus to exist as its embodiments respectively. As time passed, Arceus eventually brought life to the Pokémon universe, along with Dialga, Palkia and Giratina, ultimately seeing that all life created on viewpoint should be deserved to be treated as equal to its own existence. However, Eternatus despised all life in the Pokémon universe, as it found them to be pointless and beneath itself, and dedicated its entire existence to wiping out countless worlds for its own amusement. Upon taking notice of its sibling's destructive activity, Arceus furiously attempted to put a stop to Eternatus' rampage, but the resulting battle ended in a stalemate. In order to finish this seemingly endless fight in its favor, Arceus sought help from the Creation Trio and with their combined might, Eternatus was defeated and cast out into another dimension. While Arceus went to sleep, Eternatus vowed to get revenge.

Trivia

 * This version of Eternatus can naturally only briefly assume its Eternamax form by using Eternabeam.
 * In addition to that, this Eternatus is also Arceus' evil counterpart and is the only known Pokémon to be a match for Arceus in battle.
