The Other

"The Tesseract has awakened. It is on a little world, a human world. They would wield its power, but our ally knows its workings as they never will. He is ready to lead, and our force, our Chitauri, will follow. The world will be his, the universe will be yours. And the humans, what can they do, but burn?"

- The Other to Thanos

The Other was Thanos' personal servant. He provided Loki with the Chitauri army in an attempt to conquer the Earth and claim the Tesseract.

Biography
The Other served Thanos while he was helping Loki. After Loki arrived on Earth, he contacted Thanos, and the Other threatened the God of Mischief, declaring that if he failed in defeating the Earthlings, Thanos would make him know a new kind of suffering.

When Loki was eventually defeated, the Other complained to Thanos that the Earth's inhabitants were not as weak as they were supposed to be; he declared that challenging the Earth's heroes would be to court Death itself. To this, Thanos simply smiled.

Some time later, The Other contacted Ronan and Nebula through a holographic screen and told them to visit Chitauri Space to discuss Gamora's betrayal and the loss of the Orb. This led to an argument with the Other, who lectured the pair on showing respect in Thanos' presence, ultimately prompting Ronan to kill him, twisting his head 180 degrees with the power of his hammer.
