Although Starmie have ten limbs, it is typically only the top three (and the core) which can be used in combat; the others are for balance and movement. Furthermore, the difficulty of concentration allows attacks from only one at a time. (Typically, a trainer will teach them to shoot water out of the uppermost limb, electricity out of the upper left, and ice out of the upper right, while the core is used for psychic power, although many techniques and combinations are possible.) Despite this limitation, Starmie are so powerful, so overused in Pokemon Leagues that fans are often annoyed to see them.
History, however, tells of a legendary trainer whose Starmie learned to attack not with three limbs at once, but with all ten! The technique was called Decattack. It began by jumping into the air while the core glowed purple and allowed the Starmie to levitate in place. The ten limbs curved forward, giving the impression of an artillery piece, then fired from all of them at once with an attack which used all eight of the so-called "special" or "elemental" types, along with flying (wind) and poison.
If the foe did survive, they would be crippled by burns or paralysis or any of the other deadly effects which Lum Berries heal. Most of his foes carried Lum Berries or Focus Sashes, such was his Starmie's reputation. He won six League Championships in a row, then retired, claiming there were none alive worth battling. Some say he lives in Mount Silver to this day, waiting for a worthy opponent – Red searched for him, but never found a thing.
