Three Hundred is a character made of 300 blocks. Her debut was One Thousand and One, in One and One Hundred's imagination. She looks like a big Three, and she has a crown.

She is voiced by Beth Chalmers.


  • 300 is a triangular number (1-24 added together). Despite this, she doesn't have a Step Squad mask. This is most likely because they didn't know 300 was a Step Squad, and they forgot to check. Either that or they just wanted her to be a Giant Three, no Step Mask. There could also be a chance that the official 120 and 190 might not get Step Masks either.
