Jax and Rammus are the only champions that species we have no idea about

Add Skarner here as well since we know very little about his species as well

Meh. Rammus is an armadillo (demi)god. That's clear. It's just Jax and Amumu.

Actually I'd argue that this goes for as well. I mean her lore claims she is a celestial being, but we have seen that there are several different kinds of celestial beings, so what is she? An Aspect like old Pantheon? A spirit like Bard? Or is she closer related to Aurelion Sol?(I remember a rioter saying that Sols siblings aren't necessarily dragons)

Or maybe she is none of the above.

Also we don't really know if is really human considering that his new lore makes it so that he was already that way as a baby.

Pretty sure Jax is a dude who has undergone some level of corruption or modification throughout his years.

In other news, water is wet.

Isn't Jax confirmed an Icathian who was slightly voidtouched? We even know his real name.
