What do Bugs, Unholy creatures and Robots have in common? - Hexagons!

In our game Hex to the Max you summon creatures by placing hexagons on a grid, going for big numbers and chaining sick combos.
We settled on bugs, the unholy and robots as themes more or less randomly based on discarded game ideas. Only afterwards did I realise:
Hexapods
Hexes
Hexcode (okay, this one is for colors - hello, artist here :wave: - but still!)
