Kayle x Pantheon
Wait... this isn't a troll ship post.
and
are 2 champions that share an interesting dichotomy in the lore. Both are demi-Ascended beings in their own rights, Kayle being the daughter of the Aspect of Justice and Atreus who took up the weapons of the fallen Aspect of War.
The dichotomy occurs where Atreus loathes his godhood and values his strength as a human, however, Kayle believes that her humanity is the source of her imperfections and values her godhood as her source of righteousness. I believe an interaction between the two can lead to some character progression where both learn to accept a little bit more the parts of themselves which they loath, by seeing the other in action. Kayle left for the celestial realm a top Mt Targon so I believe the potential encounter is possible.
I don't think they would solve each other's problem, but rather prompt character progression from where Kayle can go back to Morgana and begin to understand her sister's view of humanity.

That said... I'd ship them.
