Angelica is the main antagonist of the series, who bullies and bosses her younger costars around and treats them as her slaves. Because she is older than the babies are, she is able to talk to the adult characters on the series (while the babies can only communicate with each other and Angelica) which she uses to take advantage of them. Angelica can best be described as the beautiful, spoiled, vain, sarcastic, selfish, bratty and antagonistic cousin of Tommy, Dil Pickles and Helga G. Pataki. She is known for her frequently manipulating the babies for her own gain and calls them "dumb babies", and thinks she is smarter than them. When the character Susie Carmichael was introduced, she was soon favored among the babies, causing Angelica to start a rivalry with her. She'll say and do anything to get what she wants, even though it normally just gets her into, most of the time, serious trouble.
