Cull Obsidian

Cull Obsidian was the strongest of Thanos's children and a member of the Black Order.

Attack on the Statesman
Cull Obsidian was one of Thanos' children, and a member of the Black Order. The largest and strongest of the Order, Cull Obsidian participated in Thanos' assault on the Asgardian ship Statesman in search of the Space Stone. During the boarding action, Thanos was attacked by the Hulk. Cull Obsidian moved to intervene on his father's behalf but was restrained by Ebony Maw who told him to let Thanos have his fun. With the Space Stone added to the Infinity Gauntlet, Thanos teleported himself and his children away from Statesman as it exploded.

Attack on Greenwich Village
"So, what is this guy’s problem, Mr. Stark?" "He's from space, and he came here to steal a necklace from a wizard."

- Spider-Man and Iron Man

Under orders from Thanos, Ebony Maw and Cull Obsidian traveled to New York City on Earth in an effort to secure the Time Stone from Doctor Strange. Their ship caused panic and devastation on the streets of New York, and the pair were opposed by Doctor Strange, Wong, Iron Man, and Bruce Banner. Iron Man intended for Banner to Hulk out and take on Cull Obsidian, but Banner was unable to transform. During the battle, Wong used his magic to teleport Cull Obsidian to a snowy region of the planet. As Cull Obsidian tried to return through the portal, Wong closed it, cutting off his forearm.

Battle of Wakanda
"Oh, no you don't. This isn't gonna be like New York, pal. This suit's already kicked the crap out of the Hulk."

- Bruce Banner

Cull Obsidian was present at the Battle of Wakanda, leading Thanos' Outriders alongside Proxima Midnight. As the battle raged, the Children of Thanos attempted to secure the Mind Stone from Vision. Cull Obsidian was engaged by Bruce Banner using the Hulkbuster armor. During the fight, Obsidian managed to detach the Hulkbuster's left arm. Banner then trapped Obsidian's arm in the gauntlet and activated the inbuilt thruster. Obsidian was sent flying into the sky where he bounced along the inside of the forcefield protecting Wakanda until he exploded.

Personality
Cull Obsidian was savage brute that took great pleasure in fighting his enemies. He was eager to fight the Hulk on behalf of Thanos during the attack on the Statesman before being stopped by Ebony Maw. In contrast of his siblings, he was apparently the least intelligent of the Black Order.

Powers and Abilities

 * Superhuman Strength: As a result of his great size, Cull Obsidian possessed an incredible level of superhuman strength, seemingly on par with that of the Hulk, indicated by Cull intending to fight the Hulk for his master Thanos when Hulk attacked the Mad Titan. Cull's strength allowed him to fight on par with, and even overpower, the Hulkbuster, a weapon that was able to defeat the Hulk. In fact, Cull was strong enough to easily rip the Hulkbuster's arm off.
 * Superhuman Durability: Cull Obsidian possessed superhuman durability, taking numerous blows from Iron Man's enhanced nanotech suit, the Hulkbuster armor, and even a full blast of Black Panther's kinetic energy projection, all with absolutely no sign of harm. However, Cull's durability appears to have a maximum limit, since he was destroyed when Bruce Banner's detached Hulkbuster arm lifted and dragged Cull into the intense energy of Wakanda's barrier.
 * Cybernetic Arm: Cull Obsidian had his right forearm replaced with a prosthetic, having lost it when it was trapped in a magic portal that was closed, severing his arm.

Equipment

 * Cull Obsidian's Hammer: Cull Obsidian utilized a massive multi-tool like weapon that had a wide range of abilities. It was primarily used as a hammer and the head of the hammer could be launched attached to a chain to hit targets at a distance. It also possessed a claw like function, being capable of grabbing targets. It could also be used transformed into a shield that was capable of deflecting energy blasts.
