Annihilus possesses immense strength, stamina, and durability. Large bat-like wings enable him flight, even when they are badly damaged.

The Avengers: Earth's Mightiest Heroes
Annihilus is the ruler of the Negative Zone, and apparently lacks the ability to talk. When he discovered Prison 42, he sent his bugs to attack it and get through the portal so that he could get to Earth and destroy life. Thor, Captain America, Ms. Marvel, and Wasp defended the prison with the help of S.H.I.E.L.D. and the remaining prisoners. Annihilus later came to fight them, killing Radioactive Man, Blizzard, and Whirlwind with his Annihilation Wave. The Avengers could not attack him due to his force field, but The Leader disrupted his shields and made him easy to attack. The Avengers then separate him from his Cosmic Control Rod causing his bugs to turn on him and then flee, leaving Prison 42 damaged and the inhabitants standing.

Hulk and the Agents of S.M.A.S.H.
After countless efforts, Annihilus managed to open a wormhole above Vista Verde with intentions to invade Earth and strip it of its natural resources. Despite his refusal to fight the Hulk, he sent Skaar through the portal to attack him. Eventually Skaar managed to free Annihilus from his inter-dimensional, and sent his bugs to attack the Hulks. However, the blast from the Gamma Core caused the portal to close, but not before Annihilus' bugs to capture Red Hulk and Skaar. Hulk, She-Hulk, and A-Bomb later travel into the Negative Zone itself to rescue the two Hulks. Annihilus, watching their efforts, sends his bugs along with the brainwashed Red Hulk and Skaar to attack them. While the team freed the captured Hulks from mind control and fought off the bugs, Hulk went off to confront Annihilus himself. Using the Cosmic Rod, Annihilus attempted to regress Hulk back to his original aggressive state, only for Hulk to grab Annihilus' Cosmic Control Rod and renders Annihilus powerless. Annihilus claims that his hordes will still wipe out Earth until Hulk bends the Cosmic Control Rod in two, seemingly disintegrating Annihilus. It was later revealed that Leader was the one who supplied Annihilus with the mind-control technology.
