"Really loudly, sing... SUPER SHAPES!"
— Geo to the viewers, while building the Shape Bandit's new house.

Geo is Milli's brother. These are his powers:

  • Super Shapes
  • Shape SPLITTER

Geo is very nice to his sister, as he helps her stay asleep while he's around. Evil-Man, on the other hand, doesn't like it when she is sleeping (she snores loudly) and tries to wake her up.

Ethan Kempner is Geo's voice actor in Team Umizoomi, as well as Barney and the Rocko Squad.
