W.i.t.c.h.

Irma has the power to control the element of water, often condensing the water vapor in the air into liquid water and then use it as powerful blasts of water. She eventually starts manipulating bodies of water to stop rushing water or create shapes like swords and can create a bubble of water filled with air to travel underwater. She can also manipulate the water in the clouds to make it rain and control water pressure allowing water under her control to grab objects or even slice through metal, rock, and leather.

Later when the Guardians powers are fueled by the energy used to create the Veil, they begin manifesting new powers. Irma gains the ability of mind control, able to influence and control people's actions, such as making her father go easy on her to avoid grounding or breaking another free from outside mind control. She cannot override the effects of the Horn of Hypnos or Nerissa's enthrallment spell but when the power of those things weaken she is able to break it.

Irma also displays more power with her power over water able to freeze and evaporate it at will, dehydrating AKA sucking the water out of beings, and creating a gigantic version of herself at water using herself as a nexus of this watery giant.

Like all of the Guardians, Irma's stamina, agility, and speed are increased and they all possess wings that allow them to fly.

The Inner Irma Lair

Irma Lair is also a fan of Karmilla as she always say.  Karmilla is a rockstar that she admire the most. She attends  concerts and purchases her merchandises.

Irma also loves annoying her brother and playing with her turtle pet. She loves pulling pranks on others and give new nicknames to others. The most notable nicknames that she gave were Hay hay for Hay Lin and Corny for Cornelia. She is the team's joker.
