Diamond "Will-get-you-fired' Tiara

Diamond Tiara was first appeared to be selfish, sadistic, rude, merciless, and overall bratty. Her closest (if not only) friend is Silver Spoon, who often acts as her follower and usually on her side. She views those that doesn't have cutie marks as an inferior and mockingly referring them as "blank flanks", particularly Cutie Mark Crusaders, whom she always picked on. When the Crusaders are being happy or her plans and schemes are being ruined, she will rather getting angry/shocking reaction or complaining when things don't go in her way. She is willing to encourage them to make stories in "Ponyville Confidential" and would do anything to blackmail them to prevent them from resigning. Despite this, she is hinted to have redeeming qualities, as she will try to "befriend" the Crusaders, as seen in the episode "Twilight Time".

Despite she always acts due to her mother's teachings, she secretly wanted to become a better pony, but failed to realize that bullying and inflicting pain towards others doesn't make her happy. After she stands up to her mother, she finally developed her kinder and generous personality, donating her money to the school and guiding other ponies through her natural-born leadership.
