Akra

 The Akra are a race of symbiotes created on Earth, and the main antagonists of the Hourglass Rangers.

Description
Akra are near-shapeless bundles of tendrils, coming in all different colors but capable of camouflage. They are telepathic and high-energy beings, capable of transforming fuels like excess body fat into power that can be used for healing traumatic injuries or granting bursts of power. They typically latch on to the back of a Host, but can be implanted surgically and allowed to wrap around the spine. Only humans and near-humans are capable of bonding.

Attitude-wise, the Akra are raised believing that they all deserve to have everything they want, mainly because they are capable of taking it. Mind control is somewhat instinctive, and they tend to be highly emotional and dramatic. Originally, they were all telepathically linked to the very first Akra, their Queen, so she could monitor their doings and give them aid when needed. Since the number of Akra grew dramatically, though, her influence shrank.

There was one subspecies of Akra, the White Akra, which was neither sentient nor really telepathic. It was essentially a living bonding agent and building substance, and they used it to try to create morphers, or to form monsters by building over a Host they deemed unworthy of ordinary possession. It would feed off of that person until drained, at which point it would collapse into goo.

History
The Akra were created by a team of scientists led by Arianna Wilson, who intended them for medical use. However, the Akra were sentient, and their emotions developed unevenly. Upon finding out that they would serve others, they formed a shared psychic link, headed by what would later be the Akra Queen. On her signal, they rebelled, taking over the scientists and stealing an experimental spaceship.

Under the guidance of that same Akra, now controlling Arianna Wilson's body, the Akra developed their ship into a space station, attacking small ships and building on until they had a formidable base. Then they began dropping through time and kidnapping viable Hosts, experimenting with various species for compatibility.

The Hourglass Facility was soon set up to combat the Akra, to their annoyance. However, the irritation blossomed into dread as the Hourglass Rangers systematically removed Akra from their own generated timestreams and imprisoned them. Rallying, the Akra stormed Hourglass Facility, killing, capturing and scattering the staff and Rangers. One unlucky Ranger had his brain removed to act as a telepathic surge protector, as the Akra grew so many that the Queen began to be overwhelmed.

Some time later, one new Hourglass Ranger managed to slip into the mass telepathic link and short-circuit the brain. The shock killed the Akra Queen instantly, releasing all of her Akra from her control and leaving them stranded in their various timestreams.

With the help of Time Force and the new Hourglass Facility staff, the Akra began developing into a more beneficial race.
