Attuma possesses various superhuman abilities common to the Atlanteans. However, his strength, stamina, resistance to physical injury, and swimming speed are much higher than the majority of his race. Like most Atlanteans, Attuma could not survive out of water for more than 10 minutes without the aid of mechanical devices or certain chemicals, for most of his life. His stamina, agility, and reflexes also were reduced when out of the water. Like all Atlanteans his specially developed vision allows him to see clearly in the murky depths of the ocean.
