Triangles (Species.).

The Triangles, also known as the Triangleheads are an invasive and hostile alien species, created from the Void of Time, a location from which multiple entities, all rejected from reality, such as the Singulars, Symbols, Forces, Anomalies, and the infamous Pestilence, who are incredibly hostile.
As all other Void Entities, they share unique abilities, and the Triangles are in fact a confederation of different subspecies, primarily the Triangleheads, which are the majority (Roughly 75% of all Triangles), but not exclusively, as demonstrated by the Dynamos, also known as the Squareheads. All of whom will harm sentient life on sight.
The goal of the Triangles is to conquer all of existence, and to replicate infinitely. They, bizarrely, have no hatred for the entities they ruthlessly slaughter, but rather see it as simply moving objects out of the way, as though life were a dust needing to be swept up and cleaned.
The Triangleheads have insofar devoured over 500 different timelines, and have tried desperately to conquer more. Individual Triangleheads share the abilities of Anomalous Powers, namely the ability to use their Cognitive Power, especially combined, to cast spells, most notably, Dirty Reality Alterations, particularly Dirty Deletions.
Triangleheads have allied with the Xanxon Empire and it's associates.
Starting off before any recorded history, during their first expulsion, the first Triangleheads somehow managed to reproduce, at which point they immediately made contact with the relatively peaceful and harmless Singulars. They did battle, at which point, a single Singular, named Star, or ★, who had just become their defacto leader, immediately ordered a mass evacuation from their original homeland, being unable to stop the corruption by the Triangleheads, after he had received an apparent revelation from Christ. Afterwards, the newly Christian Star, leading the Singulars, desperately avoided persecution, as constant evacuation was undertaken. Unfortunately for the Singulars, they, as most other Shapeshifting and Possesser Entities, cannot stay in a single Timeline for very long, requiring a constant series of jumps every few temporal periods, typically a few years to multiple millennia. 
Eventually, they entered the Trinity-7-2 Timeline, in about 2016 AD, which was inhabited by Humans, as in the ARG Timeline. After crippling losses from the pursuing Triangles, the Triangleheads largely destroyed humanity, rapidly overrunning them, however most of the Triangles promptly demobilized to focus on other fronts. Warminds of the Trianglehead military believed there was no really chance humanity could ever come back from their damages. The Arizona Republic of the Sun, a breakaway region from the rapidly collapsing United States of America, later the United National States of America, though not actually forming an official alliance, had come to a generalized conclusion of acceptance and vague mutual cooperation with the Triangleheads, as did the Chosen, a terrorist group internationally attempting to reconquer the world in Trinity-7-2.
====== Author's Notes. ======
# The Triangleheads were initially inspired by The Bottom of The Void ARG, and credits to the name and initial body design belong with them, however, beyond the origin point (The Void), name (Trianglehead) and vague body plan (Black color, skinny, triangle for a head, largely 2-dimensional), there are no further similarities exist at this time between the two. There's no crossover nor direct copy, save for the referenced names and body plan. Credits to the original place the Triangles derived from belongs exclusively to Mark101 and the associated ARG, and no copyright infringement is intended. Changes and modifications were done so as to avoid explicit plagiarism, namely their histories and biology, as well as behavior and overall intentions, as well as everything, again, save for the names and body plan of the Triangleheads. Repeating credit for those items belong to TBOTV ARG, available here. Please support their channel, for they make amazing content!
# The name of ★ is a reference to the above ARG, as no other Singular possesses such names or patterns for their names.
