Early Life

Todd Arliss was swimmer who took part in the Olympic Games. He later damaged his spinal cord when he rescued a drowning man. Desperate to regain his swimming ability, Arliss willingly participated in an experiment by the scientist Dr. Lemuel Dorcas.[2]

Tiger Shark

He "cured" him by blending his DNA with that of Namor the Sub-Mariner and a tiger shark. Although successful, the process changed Arliss both physically and mentally: he now had razor-sharp teeth and gills and had become savage and predatory. Becoming a super-villain and calling himself Tiger Shark, he found and threatened Lady Dorma and was then crowned Lord of Atlantis.[2] The Sub-Mariner, however, soon deposed Tiger Shark and the two became implacable foes.[3] Namor and Dorma travelled to the surface to tell Tiger Shark's sister Diane Newell that he was still alive.[4]

Search for a Cure

Namor with Lord Seth tried to find the Herb of Healing to help restore Tiger Shark to human form. Namor failed in his quest to help Tiger Shark.[5] Tiger Shark was next seen near the Sargasso Sea. Namor confronted Tiger Shark who has allied himself with a group of Immortals bent on ruling the world. However, when the Immortals leave the mists of the Sargasso Sea, they begin to age instantly and die. Tiger Shark attempted to unleash a deadly virus, but Namor and the sacrifice of Dr. Newell ensure that it causes no harm. Unfortunately, Tiger Shark escapes, but Namor vows to kill him when they next meet.[6]

Saving Atlantis

Killing Leonard Mackenzie

With the help of the Human Torch, Namor drives back Krago.[8][9] Namor faced off against Llyra and Tiger Shark, but their battle is interrupted as the Human Torch shows up. An enraged Namor fights against the Human Torch not knowing that Human Torch wants to help him. Namor defeats the Human Torch and then learns that his father, Leonard Mackenzie, has been kidnapped by Llyra and Tiger Shark.[10] Namor desperately attacked Tiger Shark while Llyra keeps an eye on her prisoner, Leonard Mackenzie, Namor's father. Llyra tires of their battle and captures Namor. Stingray comes to Namor's rescue and they confront Llyra and Tiger Shark. Unfortunately, before Namor can do anything, Tiger Shark kills Mackenzie. They get away while Namor mourned the loss of his father.[11]

The Hulk

The two battled and the Hulk is submersed in water, and is easily outmatched by Tiger Shark in his natural environment. Needing air, the Hulk managed to get away long enough to surface and get on dry ground. Tiger Shark followed after him to resume the fight, this however proved to be the villains undoing. Here the Hulk easily defeated him, smashing him about and grabbing him by the fin and slamming him into the rocks before throwing his unconscious body into the waters below.[12]

Tiger Shark allied with Dr. Dorcas, who has been developing men-fish called Aquanoids to be his army of aquatic mutates. When Namor and Spider-Man arrived on Dorcas' ship, the two fight off both Tiger Shark and Dorcas' Aquanoids. However, they are forced to abandon ship when devices within the ship become unstable. Getting to safety, the two watch as Dorcas' vessel explodes, seemingly killing Tiger Shark and Dorcas in the process.[13]

Namor regained his freedom with the help of Doctor Doom, and attacked the conspirators, throwing Tiger Shark into one of Attuma’s war machines.

  • Atlantean/Human/Tiger Shark Hybrid Physiology: Doctor Dorcas' blending of Arliss' DNA with that of a tiger shark and The Sub-Mariner grants him a unique, amphibious physiology granting him a number of superhuman attributes.
    • Superhuman Strength: Tiger Shark possesses great physical strength that varies greatly depending upon the amount of time he spends out of water. His strength is sufficient enough to engage Namor in direct physical combat. While wet, Tiger Shark possesses sufficient superhuman strength to lift up to 75 tons. When dry, however, his strength is significantly less and can lift about 50 tons. The least amount of weight Tiger Shark has been able to lift is about 40 tons, but only after being dry for an extended period of time.
    • Superhuman Speed: While on land, and wet, Tiger Shark is capable of running and moving at speeds greater than even the finest human athlete.
    • Superhuman Swimming Speed: While in water, Tiger Shark is capable of swimming much faster than the finest Olympic swimmer. He can reach a top speed of 60 miles per hour.
    • Superhuman Stamina: While wet, Tiger Shark's musculature produces considerably less fatigue toxins during physical activity. His musculature also generates far less fatigue toxins than the vast majority of Atlanteans, who all possess some level of superhuman stamina. He can exert himself at peak capacity for about 24 hours before fatigue begins to impair him.
    • Superhuman Durability: While wet, Tiger Shark's body is considerably harder and more resistant than the body of an ordinary human, or most Atlanteans for that matter. He is capable of withstanding the extreme temperature and pressures of the ocean floor, powerful impact forces, high caliber bullets, and falls from great heights without sustaining injury.
    • Superhuman Agility: While wet, Tiger Shark's agility, balance, and bodily coordination are enhanced to levels that are beyond the natural physical limits of even the finest human athlete.
    • Superhuman Reflexes: While wet, his reaction time is enhanced to a level that is beyond the natural physical limits of even the finest human athlete.
    • Regenerative Healing Factor: Despite his superhuman durability, it is possible to injure Tiger Shark. However, like Atlanteans, he is capable of rapidly healing minor and moderate injuries faster than ordinary human beings, provided he is wet.
    • Aquatic Physiology: Tiger Shark's body is specially adapted for aquatic environments. His body is capable of withstanding cold temperatures and pressures that are found on the bottom of the ocean floor. He is also capable of breathing, speaking, seeing, and hearing underwater with perfect levels of clarity.


  • Olympic Swimmer: Before gaining his superhuman powers, Todd Arliss was a record-breaking Olympic swimmer. His sheer strength and physical toughness make him a formidable combatant.

Strength level

  • Class 75;[103] Tiger shark can lift up to 75 tons when well hydrated.


  • Tiger Shark's vitality is dependent upon regular exposure to water. The longer he is out of the water, most of his superhuman abilities rapidly dwindle. If he is removed from water long enough, it could prove fatal.


  • Tiger Shark's costume is specially designed and contains a built in water system that constantly keeps his body wet. This keeps him in peak physical condition if he's out of the water.


  • Adamantium teeth When he appeared as a member of the Offenders, he had Adamantium bonded to his teeth. It is unknown how or when this happened.
