I discovered the origins of both Jhin and Kindred

Kada Jhin was once upon a time a fan-designed champion named Kadarin, who was the result of Total Biscuit giving away his "Design a Champion with the rioters" reward for 10K referrals with the old referral system. He donated it to the Make-A-wish, and recipient went on to design Kadarin.

Kadarin was a bounty hunter from outer space, and the prototype of Kindred and Jhin was a robotic bounty hunter champion created in 2015. The recipient went to Riot in 2015 to design the champion. Seeing the relation?
