Plot Device

Plot Device is the Omnitrix's DNA sample of an Infinitum from Shimmering Solitude. He existed briefly only in Earth-58. He is Aaron's entry into the Fall 2019 Fanon Con Alien Design Contest, under the theme of 'impossible'.

Note: I am aware that Fanon Con Alien Entries require sections for their planet and species. That is not possible here, for reasons that should be obvious once you've seen their pages. For full context of this alien, the relevant pages are:
 * Earth-58
 * Infinitum
 * Shimmering Solitude

Appearance
Plot Device is a large, floating non-humanoid creature with inky black skin. His body consists of a chest as large as a torso, connected by a thin abdomen to a large thorax hanging underneath. He has two large and thin arms, and two smaller arms holding close to his chest. All four of his hands have four fingers arranged in a circular pattern around the palms.

He has a long, almost canine-like jaw. He has large glowing blue/purple teeth and a bright orange tongue (or even tongues, they seem to change between one long, wide tongue and many thin tentacles tongues at random). None of this seems to fit into his mouth, yet it still closes perfectly. He has four eyes on the underside of his jaw with black sclera and orange irises. Atop his head he has long glowing blue opposable tendrils.

The Omnitrix dial is on his left shoulder.

Powers and Abilities
From a meta perspective of truly knowing the nature and context of Plot Device, his powers are clearly Plot Control. However, from Ben's perspective he only knows one thing- when he presses the dial onto Plot Control's silhouette, there is a 100% chance that he is going to succeed at whatever he is attempting to achieve regardless of nature even if he mistransforms into another alien.

Plot Device, named because of his sure-fire success rate, has the ability to alter the future in his favour both consciously and unconsciously though only to a somewhat minor degree. There are rarely, if ever, consequences for actively altering the future that he is unable to proactively perceive. These powers even extend to the Omnitrix itself, meaning that attempting to use this alien will often result in Ben being given a more suitable alien for the scenario.

His only other real power is his ability to float on any surface, but only at a shallow height.

Weaknesses
This alien is, above all else, the alien that Ben is least likely to actually get when he selects it- especially if he wishes to use this alien in combat. Not knowing what alien he will actually get and not always being sure how this alien will help both led Ben to sometimes avoid this alien. He eventually overcame these worries, however, and began trying to use him near-constantly.

His massive teeth are far too soft to actually bight anything.

He cannot throw a punch to save his life.

History
Plot Device was first unlocked accidentally and used when the Tick attached itself to Earth. An unseen side affect of Plot Device's powers caused a bacteria from Arburia carried by the Tick to mutate when exposed to Earth pathogens, that fed on the Ammonia inside the Tick and rapidly killed it from within. Ben was stuck as this alien for several hours during the alien attack.

Eventually as Ben began to use the alien more and more, greater and greater alterations to the timeline began to occur, such as Max successfully convincing Xylene to stay on Earth to help them protect it. Though this had minimum impact on the events immediately succeeding her remaining, this became greatly important when Ben accidentally tripped the Omnitrix's self-destruct. They were immediately able to take the device to Azmuth and have it fixed.

From here, the timeline began to majorly diverge. Plot Device's existence allowed Ben to surpass the events that SHOULD have triggered him wanting to remove the Omnitrix when he was 12. This led to a vastly different course of events for the next few years as Ben's continued service invited greater challengers to face him. Khyber made himself present far sooner, and the Highbreed invasion was discovered quickly and effective measures prevented them from ever taking a foothold while still allowing Ben to reach Augstaka and repair the Highbreed DNA to prevent the genocide of the Milky Way Galaxy.

Eventually, the events shifted so far from the set path as to invite worry from the Celestialsapiens when the consequences of Plot Device's alterations suddenly became too much to overcome as Ben was unable to prevent Aggregor from reaching the Forge of Creation and nearly absorbing a Celestialsapien child had its mother not been able to protect it herself. This complete failure of the time loop fundamental to Earth-58 prompted them Celestialsapiens to take action against the beings that had caused this universe to vary so much from those that came before it.

Plot Device was removed from the Codon Stream and, in essence, completely destroyed. The Infinitum were completely removed the universe and a new, separate, universe was created specifically to contain them. This dimension is known as The Cell.
