Have the teens but as Heroes with Zeroes! I had the idea to nickname them "The Adults" since they're basically larger versions of the teens. They all have similar personalities to their normal counterparts, though some are different in a few ways. 110 (F) - Big Footballer, the greatest footballer out there. 120 (F) - She's incredibly rectangly (SHCN to be exact), much more rectangly than 12. However, she acts a little more like 15 since she's also the 15th step squad, and 15 is an agent. Mostly, she's very zen. 130 (M) - Is more used to his bad luck than 13. If anyone says his name, his 30 goes flying off. 140 (M) - haha double lucky 70 go brrrrrrrr 150 (F) - Is an agent like 15, but she's a ninja instead (Credit to Aury for the idea and design) and not a step squad. She can however split into step shaped 15s or 10s. 160 (F) - OBLONG PARTY ALL THE WAY 170 (M) - The greatest artist of all time who paints 170 of everything. 180 (M) - Crazy like 18, plus he also sometimes spins upside down cause 180 degrees. 190 (F) - Even though she can make a good amount of rectangles and even a step shape, she still loves making crazy shapes like 19. And she can a lot more cause she has THAT many blocks.
(c) Numberblocks Also wanted to give them different expressions than usual to be a little more unique.
