It also has weapons that were stated to be strong enough to kill Adam Warlock, who has taken star - destroying attacks and survived. His armor and clothing contain a vast amount of devices that increase his stats as well as give him many different types of weaponry and allow him to draw power from various sources across the universe and other dimensions. Sometimes the Reality Gem (which allows him to warp reality, such as resurrecting the dead) is considered to be part of his standard equipment, even though he rarely uses it

- Force Block: Originally shown in the form of a gun, this weapon creates a block of force around a target. It was powerful enough to restrain Power Gem Thor (who had previously wrecked the team of Adam Warlock, Doctor Strange, Drax, Maxam, and Moondragon) for hours. Later it was shown that he had incorporated this technology into his armor/body, and it even managed to restrain Odin for a very brief period.
- Teleportation: Thanos cannot only teleport himself, but others as well, and his control of these teleportation portals was precise enough to intercept the Silver Surfer while he was flying through space at high speed. Appears to be limited to his current universe as he is currently unable to escape from the cancerverse.
- Time Mind Sync Warp: A psychic attack he used on Drax, it plunges the victim's mind into insanity, causing death or incapacitation. Drax was able to resist it for a while due to his incredible will/cosmic origins, but eventually fell to the attack, although he recovered later.
