>>43011953Clown Type
SE against Psychic (clowns are scary), Ghost (can't be spooked if you're laughing), and Dragon (dragon being the king of types and the court jester being the one who can criticize the king).
NVE against bug (bugs have no sense of humor), grass (plants have no sense of humor), ground (clowns falling down is silly), dark (too serious and edgy to laugh), and fairy (mischief vs mischief).
Weak against ground (because of falling over), water (washes away makeup), bug (hard to concentrate on being funny with bugs crawling all over you), and normal (normal people hate clowns).
Resistant to electric (joy buzzer), fighting (it would just be slapstick), rock, steel (more slapstick, think of a rock or anvil falling on a clown's head), fire (clowns do tricks with fire all the time), and fairy (mischief vs mischief)
Pokemon who'd change type are the Mime line, Blacephalon, Primarina, Gurrdurr, and Conkeldurr.
