Random idea that got into my mind:
This.
10-na is like the original 10, but it moves faster everytime it bounces
3^4 shoots spikes like the original 3, but with significantly faster bullet speed and attack speed. Once it shoots its 81st spike, it instantly hits your cursor/the last spot you tapped on your phone and you lose.
X, Y, and Z will come in group, they can copy any other boss' ability, referencing to how they can represent unknown numbers in algebra (if i recall correctly)
I already explained the others when i posted the older version of this photo. Still have no mechanic idea for (Infinity).
Also i made a design concept for Captain Sweeper's wife if he had one, i thought it's worth a shot.
