Thane

Thane is a fictional character and supervillain appearing in Marvel Comics. Thane is the illegitimate child of Thanos and an unnamed Inhuman woman. He was created by Jonathan Hickman and Mike Deodato and made his debut in New Avengers vol. 3 #10.

During the events of the Infinity storyline, Thanos begins invading Attilan in an attempt to find and kill his son. Upon undergoing Terrigenesis, Thane develops powers of instant death to those near him and the ability to encase others in amber, but he cannot control these powers and inadvertently kills everyone in his hometown. He is given a special suit by Ebony Maw that allows him to properly control and channel his powers, and he begins to rebel against his father. Thane is easily manipulated, having been used by villains such as J'son and Death in pursuit of their own goals. He is briefly empowered by both The Black Vortex and the Phoenix Force, but is later stripped of all his powers and trapped by Thanos in the God Quarry.

Iago PUC's ideas

 * Thane appears as the main antagonist in the Disney+ animated crossover miniseries Marvel's All-Star Multiverse, voiced by Ross Marquand. Still depicted as the half-Titan, half-Inhuman illegitimate son of Thanos, this version possesses the abilities to harness Darkforce, communicate with evil spirits, and reanimate the dead into revenants and zombies, which he uses as his minions. Following the awakening of the Multiverse Star, Thane is tasked by the spirits of the deceased dark lords Knull, Emperor Palpatine, Mephiles the Dark, Unicron, and Za-Naron to destroy the "light in the Multiverse", putting him in conflict with the Multiverse's heroes, including the Avengers, the Legendary Warriors, and the Skycruiser Commandos.
 * Thane appears in Marvel: All New, All Different Chronicles, voiced by Sam Witwer. He serves as one of the main antagonists of the second season.
