You have Gnar have special interaction with certain champs, but there is 1 important champ that is missing from his special taunts: 
Gnar NEEDS an interaction with Rengar and I have found the best thing that Gnar should say to Rengar:

Polemicist3 votesI have never heard of an idea so sound as this, yet it is not a flaw is it just hasn't happened yet. The reason for patches and such. So get people to up vote for it if you believe in it. Share if with your friends and lets do this. Before time goes in reverse and gnar never even happened as a champion. 
Knight Devout3 votes#Upon taunt
: Kitty!
: Raaaaa-eow [Starts to roar, ends up meowing]
#Upon being taunted, Rengar gets an unique debuff with no effects.
Nostalgia : Rengar wistfully reminisces the past.
#When one of the two kills the other, gains a permanent buff with no effects.
Coming of Age: It's time for Gnar to set out and claim a territory for himself.
Rules of Nature: Out here only the strong survives.
lightdragoon881 votesThe Hunt is on....again.
DeluxeOreo2 votesThat's so funny lol
BA Tetsuo2 votesKITTY!
xredstarriddlax2 votesI don't normally call things cute but I must say after hearing most of Gnar's quotes her is rly, rly, RLY cute, and having one towards Rengar would only increase his cuteness(is that a word?). DEMACLIOOO! XD oh and btw too* :3
