Eldrazi

"No matter how big your champion, theirs is bigger. No matter how great your numbers, theirs are greater. No matter how voracious your appetite, they are hungrier. That is why the Eldrazi will win."

- Kalitas, thrall of Ulamog

The Eldrazi are a race of alien devourers and major antagonists in the Magic: the Gathering Card Game. Existing for nearly as long as the Multiverse itself, the Eldrazi have traveled throughout the Multiverse, going to planes and consuming their mana. This has resulted in the destruction of numerous planes and an untold number of deaths. Once one of the main titan Eldrazi find a plane with a sufficient amount of mana, they form avatars to enter that plane. Then, they spawn drones and processors to absorb the mana from the inhabitants of said plane and the plane itself. Once completed, the titan leaves and the plane is left as a husk. They are necessary sustain the ecosystem of the Multiverse. The Eldrazi have posed as threat to numerous Planeswalkers, but few were strong enough to face them.

Ulamog
Ulamog is considered the weakest of the Eldrazi Titans. He is the titan with an appearance most similar to a humans. His head looks like a bony helmet and his body looks like a giant muscle with tentacles and two big arms. He is referred to as the "Infinite Gyre" or the "Ceaseless Hunger". This is due to the fact that Ulamog consumes all types of matter while the other titans do not. Whenever Ulamog absorbs the mana on a plane, he leaves behind a chalk-like residue behind. His brood ranges in size from the spawn being the size of a wolf to hundreds of feet tall. In appearance, Ulamog's spawn have look like spiders or crabs with tentacles, while his larger spawn look like slightly smaller versions of himself. Ulamog can also turn those who wish to serve him into thrulls

Kozilek
Kozilek has power greater than Ulamog's, but weaker than Emrakul's. He is the titan with an appearance somewhat similar to humans, but with many differences. His head looks like an orb and his body looks like a sturdy carapice with tentacles and two big arms. He is referred to as the "Butcher of Truth" or the "Great Distortion". This is due to the fact that Kozilek warps the landscapes of the worlds he visits as well as the mind's of those he encounters while the other titans do not. Whenever Kozilek absorbs the mana on a plane, he leaves behind rectangular shaped patterns behind on the earth. His brood ranges in size from the spawn being the size of a humans to hundreds of feet tall. In appearance, Kozileks's spawn have look like humanoids with tentacles and floating parts above their bodies, while his larger spawn look like varied different creatures with floating parts above their bodies. Kozilek can shatter or control the minds of beings who try to challenge him.

Emrakul
Emrakul is considered the strongest of the Eldrazi Titans. She is the titan with an appearance most similar to a squid or an octopus. She looks like a giant floating octopus with similar tentacles or hands, a sinew laced body, a cover shaped top, and a giant eye in her center. She is referred to as the "Aeons Torn" or the "Promised End". This is due to the fact that unlike the other titans, Emrakul corrupts the minds and bodys of the residents of a plane rather than a plane's landscape. Emrakul does't leave a physical imprint on the planes she visits, but the inhabitants with the weakest or insane minds get become eldrazied versions of themselves. The size of Emrakul's brood is determined by the size of the creatures she corrupts. She has the smallest brood size when compared to Ulamog and Kozilek.

Capture
For most of their lives, the Eldrazi roamed the Multiverse unopposed. Once their existence is made known to three Planeswalkers, (Sorin, Nahiri, and Ugin) the trio knew that they had to be stopped. Ugin, wanting to contained them for his studies, suggested to bind them to a plane to stop their rampage. It was chosen that the plane of Zendikar as a prison for the Eldrazi. By increasing the plane's mana, Ulamog, Kozilek and Emrakul were drawn to the amount of energy Zendikar emitted and arrived on the plane. Little did the titans know that this was a trap. Using the plane's hedrons which had binding properties, the Eldrazi were trapped in a planar prison, unable to escape. The trio of Planeswalkers went there separate ways with Nahiri serving as a warden for the Eldrazi.

Zendikar Block
The Dragon Planeswalker Nicol Bolas knew the power that the Eldrazi held and planned to free them from the hedron prison. By learning how to break the hedron alignment and manipulating the actions of three other Planeswalkers, (Jace Beleren, Chandra Nalaar, and Sarkhan Vol) the first barriers of hedrons were broken. Some of the spawn would be able to leave, but Ulamog, Kozilek, and Emrakul were still trapped. Shortly after, another Planeswalker named Nissa Reveane found Sorin and the two managed to hold off the brood. Thinking that the Eldrazi would leave if they were freed, Nissa destroyed the hedron network and let the Eldrazi escape. Emrakul left Zendikar for the Blind Eternities, Kozilek buried himself into Zendikar's crust, and Ulamog began to ravage Zendikar's surface, leaving dust in his wake.

Battle for Zendikar Block
For Many years, Ulamog was busy turning Zendikar into a chalk-like mess. Wanting to stop Ulamog, a Planewalker named Gideon Jura came to Zendikar hoping to stop the Eldrazi threat. After getting one look at Emrakul, he immediatly retreated and left Zendikar to find help. Now, with a few additional Planeswalkers and some powerful Zendikar natives, Gideon was ready to deal with Ulamog. A planeswalker named Kiora came Zendikar with a legion of sea monsters as well as using Zendikar's dangerous marine life to kill Ulamog. They put up a good fight, but Ulamog decimated them all. Gideon set his plan into motion, which was to create another hedron network to once again imprison Ulamog, which worked. With the major threat once again contained, the planeswalkers bickered about what to do with Ulamog. This didn't last long because an angry demon named Ob Nixilis absorbed the energy from the hedrons, freeing Ulamog and reigniting his spark. To make things worse, Ob Nixilis awakened Kozilek from the ground and the two titans continued their rampage across the plane. After defeating Ob Nixilis, Gideon, Jace, Chandra, and Nissa combined their powers to pull Ulamog and Kozilek's true forms into the plane. Having the Eldrazi Pinned, the group of Planeswalkers (now known as the Gatewatch) used their powers to end Ulamog and Kozilek for good.

Eldritch Moon
After years of scheming, Nahiri was ready to have her revenge on Sorin. Using cryptoliths, she managed to summon Emrakul to the plane of Innistrad. Her presence warped many of Inistrad's residents into eldrazi hybrids. These monsterous abominations raged across the plane, but met opposition from the plane's humans, vampires, werewolves and zombies. Shortly after, the Gatewatch (now accompanied by two new Planeswalkers named Liliana Vess and Tamiyo) arrived to defeat Emrakul. In a matter of moments, Emrakul knocked out every member except for Liliana. She tried to use death magic to harm Emrakul, but Emrakul healed faster than the death magic could hurt her. After Jace peered into everyone's minds (including Emrakul's) everyone was woken up and a new idea was established. With their combined powers, the Gatewatch managed to imprison Emrakul inside Innistrad's moon. It was soon revealed that this was what Emrakul wanted. Her reasoning for this is still unknown.
