Iota looks like a canine made of stone, though it has a thin body that appears somewhat frail compared to other Seru. Iota has large claws at the end of its legs and a small jewel encrusted at the top of its forehead. At Lv2 and Lv3, Iota will use an attack called Paralyzing Wave that causes damage and paralyzes a target.
Upon being summoned, Iota will run out of a separate dimension and use its magic to compress all targets on the field into a new dimensional barrier that shrinks and disappears. After a short pause, the barrier appears once again and explodes, damaging all targets.
