Powers and Ablities/Weapons

  • Milli-Measure: Milli's pigtails, but she prefers "ponytails", become a ruler, scale, Etc. She can also use it to add measurements to specific things, which was revealed in one of their promos.
  • Pattern Power: In episodes up to "The Big Boat Race", Pattern Power is, basically, applying a pattern onto an item. In episodes starting with "The Dinosaur Museum Mishap", Milli changes her dress into a pattern mostly to add somthing missing to the pattern by peeling the picture of the item off with that picture fading then more colour added, to fix a pattern or to follow a pattern to get through obstacles. Examples of her dress patterns are on Milli's Many Patterns.
  • Ponytails: Milli's hair extends to her liking. See more on Milli-Measure.
  • Karate: Milli knows how to do karate. She has powerful chop, kick, even her ponytails. She mostly uses her skills to get past pattern and remove measurements or to divide something into fractions.



Milli is really sweet, cute, and generous, but don't let her cute looks and sweetness fool you. She is also fearless, strong, and would do anything to help and save her friends. That's why she's the leader of Team Umizoomi. She's also the strongest member of the team.

Even though Milli really loves and cares for her brother Geo, she sometimes doesn't have faith in him with his ideas at first.
