Depictions in films
The more notable of her appearances include passing by Twilight Sparkle in the school hallway and smacking her in the face with her cell phone, dancing in the school cafeteria during the Cafeteria Song, and dancing at the Fall Formal. In all of her appearances, she is seen alongside with Silver Spoon. At the Fall Formal, she and Silver Spoon do a dance that resembles their pony counterparts' "bump, bump, sugar lump rump" dance.
Both Diamond Tiara and Silver Spoon appear in the film, but like in the first film, they have no speaking lines. They first appear in the school gym as they work on their poster for the upcoming Musical Showcase. Both girls later appear in the cafeteria when the Dazzlings' sing their song to brainwash the entire of CHS to turn the Musical Showcase into a Battle of the Bands. They are last seen only in the audience during the Battle of the Bands.
Diamond Tiara is briefly seen watching the Rainbooms' concert.
Even through her personality is not shown in the movies, Diamond Tiara is actually rude, shallow, stuck up, sarcastic, and nasty. Her closest (if not only) friend appears to be Silver Spoon, who often acts as a follower and is usually seen by her side. She sees those without their cutie marks as inferior. Despite the Cutie Mark Crusaders often being the subject of her ridicule, she will try to "befriend" them if something is in it for her.
