Favour timeline — the windows in Gnar's game plan

Read from Gnar's seat: which stage windows this plan plays for against Zac.

StageFavouredWhy
Level 1GnarMini's ranged autos plus a Boomerang win the first trade clean — Zac's only engage is Slingshot, and with it down he has no way to answer ranged poke.
Level 2GnarGnar's Hyper third-hit proc and a caught Boomerang land a free chunk before Zac has any passive blobs on the ground to reclaim the health.
Level 3Even / skillGnar still kites with the Boomerang slow and Hyper speed, but Zac's passive sustain starts refunding the poke, so the edge flattens to even.
Levels 4-5Even / skillPure Rage RNG — Mega Wallop's stun into a wall-flung GNAR! kills, but stuck in Mini with Rage down Gnar is a fragile target for the Slingshot-into-Q chain.
Level 6Even / skillZac's Let's Bounce! ult comes online — with Mega up Gnar wall-combos, without it Zac bounces in and revives, and the window is his.
First itemEven / skillGnar's first-item poke peaks, but Zac's blobs heal it and his HP scaling answers the burst, so neither side clearly owns the window.
Two+ itemsZacZac out-scales — HP stacking, blob sustain and passive revive let his evenly-traded body outlast Gnar's form-dependent Mega burst, so play teamfights not the duel.

How to beat Zac as Gnar: the early game

Mini form owns the first two levels here — Zac's only engage is Elastic Slingshot, so respect its range but punish him hard whenever it is down: ranged autos plus a Boomerang win every short trade and he has no instant way to answer. Level 2 is Gnar's spike — the Hyper third-hit move-speed proc plus a caught Boomerang lands a real chunk before Zac has a single sustain blob on the ground to reclaim it. The one trap is greed: over-extend to poke with Slingshot up and he slings in, lands his Q knock-up into W, and that combo on the squishy Mini body hurts more than anything Gnar did to him. Bank the early lead and respect his all-in once he hits 6.
