Is it okay to use name of registered trademark's name?
Friend has been using trademark name within her artist name.
For example: Ninja Keroppi, Samurai Kero, Shonen Badtz Maru or Lady Pikachu.
She has been using the name as a stage name when performing music. Also she has been wearing the the trademark on t-shirts or hats on stage and included them on album cover. She wears pikachu on her shirt or on the hat when performing. The clothing were bought from store. The image was not altered. The album cover was completely drawn from a friend that includes the character Pikachu. At the moment, her performances are non profitable and for fun. She wants to grow as an artist and begin performing at venues and charging people to come see her perform.
Is she in risk of illegal actions or sued?
Note: Personally I think she is at risk.
I wouldn't worry till you try to market your line of clothing with the image
