What the Rift Lab holds on this champion: the kit as Riot publishes it, the build the lab reviewed, and the matchups it has documented. Anything the dataset does not record is left out rather than filled in.
Riot's own text for each slot, in the order the champion learns them.
Gnar generates Rage when dealing and receiving damage. At maximum Rage his next ability will transform him into Mega Gnar, granting increased health, armor, magic resistance, and attack. Back in his Mini Gnar form he will still gain move speed and attack speed and range.
Gnar throws a boomerang that damages and slows enemies it hits before returning to him. If he catches the boomerang its cooldown is reduced. Mega Gnar instead throws a boulder that stops on the first unit hit, damaging and slowing everything nearby. It can then be picked up to reduce the cooldown.
Gnar's attacks and spells hype him up, dealing bonus damage and granting him Move Speed. Mega Gnar is too enraged to be hyper and instead can rear up on his hind legs and smash down on the area in front of him, stunning enemies in an area.
Gnar leaps to a location and bounces off the head of any unit he lands on, traveling further. Mega Gnar is too large to bounce and instead lands with earth-shattering force, dealing damage in an area around him.
Mega Gnar throws everything around him in a chosen direction, dealing damage and slowing them. Any enemy that hits a wall is stunned and takes bonus damage.

One slot, changed when the enemy team changes the problem. These are answers, not automatic purchases.
Ability text and the in-game title follow Riot's official Wild Rift champion pages. The tier letter is the external snapshot shown on the tier list, and the build is the Nexus reviewed snapshot — neither is a win rate.
In the matchup data documented in Rift Lab, these are the harder matchups for Gnar: Renekton (Baron / Top), Fiora (Baron / Top), Jax (Baron / Top), Irelia (Baron / Top), Sett (Baron / Top). This is a documented matchup list, not a win rate: TheNexus does not publish win-rate or pick-rate figures it cannot source.
Riot's ability text for Gnar describes crowd control (a stun, root, knock-up, pull or similar) in HYPER / WALLOP (ability 2); a dash, leap or blink in HOP / CRUNCH (ability 3). Plan around those abilities before a trade or a fight. These notes are keyword matches over the ability text only, not a rating of how strong Gnar is, so read the full descriptions on this page.
The Nexus-reviewed core build for Gnar, in purchase order: Trinity Force then Black Cleaver then Sterak's Gage then Plated Steelcaps. Runes: Fleet Footwork, Demolish, Second Wind, Perseverance, Brutal. Situational swaps: against enemy crowd control: Mercury's Treads; against enemy burst: Bone Plating. This is a reviewed snapshot (patch 7.2b), not a build ranked by win rate.
Gnar is a Fighter and Tank by Riot's classification and is played in Baron / Top. Riot rates the difficulty High. On our tier-list snapshot (patch 7.2b) it shows S tier from its external source, which is a snapshot letter and not a TheNexus win rate.
Every answer here is built from Rift Lab data and Riot's own ability text. Where the data is missing we say so instead of guessing.
