Irma is a spunky, cheerful, optimistic, and humorous person. Compared to the other members of W.I.T.C.H., she is the cockiest member of the team and she often appears to be the least serious as she is known to crack jokes about almost anyone she comes in contact with. Despite her tendency to joke around when faced with a problem, she is a kindhearted person who cares about those she has relationships with. She can often be seen using her powers for personal gain. When necessary, she exhibits leadership qualities. Irma almost always wants to be center stage, and, depending on the person, can or can't hold grudges for long. She also has a big appetite.
