Krel: the Living Firestorm was a canine-like Plasma 
Ravager 
from the planet Cryos.
He shared his Type and Class with Blitz . His alpha variant could be unlocked by the player at Crogenitor Level 11
Revelation
Krel was first seen in the Darkspore Gameplay trailer as one of the heroes who flashed by the screen at the beginning. After he was seen again in SRS-42's squad deck in the Loot Collection Trailer, his name was revealed on the Darkspore forum upon request by senior systems designer Paul Sottosanti. He was recently shown on the PvP producer diary. The Editor video confirms Krel as being a Ravager.
Lore
Before a Crogenitor found him, Krel had wandered across the frozen deathlands of Cryos. Facing death by exposure, Krel faced creatures twice his size, but he refused to die, knowing that if he did, so would the thousands of eggs he'd left back in his nest. No matter what, he would bring back food so when they hatched, his progeny would survive.
But eventually ice storms became even more powerful than predators, while Krel lay dying, a Crogenitor appeared to him in a pillar of lightning, and having been impressed by his fighting spirit, transformed him. Krel arose, no longer a being of mere fur and flesh, but possessed the power of a star. But the Crogenitor who transformed Krel had motives more than mercy for an individual-he knew the Darkspore were coming, and with them, a horror-storm of mayhem and death.
By the time Krel returned to his nest, dragging with him the charred carcass of a megabeast he'd slain, he found all of his children dead. In one mass mutation of eggs, the Darkspore wiped out the hope of a future for Krel's entire species.
Krel stalked his foes, stunning them with fiery barrages, unleashing twinblazing attacks and triads of fire arrows. And thus, Krel, The Living Firestorm had become the scourge of every monster who haunted Cryosi territory.

Trivia
- "Krel" is the name of a hyper-advanced species in the classic movie "Forbidden Planet", in which a human space crew discovers that the Krel were destroyed when they created a machine that turned thought into reality, and inadvertently created a huge invisible beast formed from their subconscious hatred and anger. The beast is only seen when the crew fire lasers upon it, causing its silhouette to shimmer and glow and showing it to be a fiery dog-like monster. Krel, the Darkspore hero, looked vaguely similar to this "Monster from the Id".
- In Krel's dance, it was shown that he is capable of standing on his hind legs.
- Krel's cashout weapon variant was called "Nova Blaster", which also happened to be the name of a device from the original Pikmin game. Although both devices were similar in appearance and abilities, this is, however, more than likely just a coincidence.
- Krel's abilities were balanced between physical and energy damage, making him one of the most useful heroes for fighting elites.
- According to Krel's lore, Krel was once covered in fur, making his original species very wolf-like in appearance.
- Krel's artwork was one of the few artworks that shows the hero's feet.
- Krel was very similar to a dog.
