Tenebrous is made from cheap/ fake hottoys hulk. And some Eva Foam.

The complete history of Tenebrous is unknown. He has existed in this universe since its infancy. He is a proemial being. It is said that he prepared what existed for what is to come, by eliminating early lifeforms such as the Chaos Mites. It is documented that ages ago he was known and feared as Tenebrous of the Darkness. Time has erased nearly all of his evil. In an early battle of the Gods Tenebrous and the female proemial God Aegis were among the only remaining survivors of a brutal battle with Galactus. They were imprisoned in the prison planetoid known as the Kyln by the World Devourer Galactus. The Kyln is located at the edge of the universe in a sector known as the Crunch Cascade. They remained locked in there for centuries.
