Gnar is Teemo 2.0 | Help me vs Gnar

Except Teemo isn't useless late game.

Everything about Gnar is just so disgusting going against him, lane phase, mid or late game.

His laugh, his kit, his look, even the two stupid skins he has, he is a walking cancer cell.

Pick a melee champion against him? You'll get out traded, even if you catch him out of position, E, Q, AA, AA and bam he gets to be the decision maker if he wants to chase you instead or let you get off safe. Oh, and running from him is another fun thing if he decides to chase you with that Q slow and W 3 hit movement speed steroid packed into him, you'll be lucky to escape without losing half of your health!

Same with farming, Q, AA, AA or if you're lucky, he'll go into mega form and proceed to stun you and chunk your health and you can't do anything about it since mega form makes him a super tank!

I mean yeah you could pick a ranged champion into him and that may work until he goes mega form, but then top lane is not a tank, and in low ranks, no one ever considers about picking a beefy mid.

Can someone help me on what to do vs a Gnar?
