Almighty Tallest - Secondary Characters

Secondary Characters

• Almighty Tallest (Kevin McDonald as Purple; Wally Wingert as Red): Twin leaders of the Irken race. The Irken Empire has a hierarchal class structure, where shorter individuals are both figuratively and literally looked down upon. The tallest Irken born in a specific generation takes command of the Empire as "the Tallest", but since Red and Purple, the two current Tallest, are exactly the same height, they share equal (and high-supreme) power. They are not related, as it sometimes seems, which is proved in the unaired episode "The Trial". Their main hobby is making fun of Zim. They often demonstrate an unsettling obsession with snack food and puppets.
• Professor Membrane (Rodger Bumpass): A scientist who hosts the popular television show Probing the Membrane of Science and the father of Dib and Gaz. Membrane's scientific abilities are offset by incredibly poor parenting: his primary method of managing his children is by way of a floating digital projection screen-and his messages to them are often not only prerecorded, but woefully out of date. He has sometimes urged Dib to give up on the paranormal and focus on "real science". His scientific achievements ranged from useful to bizarre, ranging from restoring power during a blackout to useful inventions like "SuperToast".
• Ms. Bitters (Lucille Bliss): The teacher of Zim and Dib's class. She is a tall, slender, and elderly woman who is devoid of any compassionate emotion and possesses a demonic hatred for life. She is often shown applying the school's unreasonable rules, or applying unreasonable punishments of her own invention for comedic purposes, often on Dib. She often slinks around to the sound of a rattlesnake and is often shown literally emerging from people's shadows. This and other factors often serve to hint Bitters as not being a human throughout the series, although this may be intended for comedic purposes rather than an actual characteristic of hers. Ms. Bitters, or at least a character highly resembling her, is also a teacher in creator Jhonen Vasquez's comic series Squee.
