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.
Dr. Mundo resists the first Immobilizing effect that hits him, instead losing Health and dropping a chemical cannister nearby. Dr. Mundo can pick it up by walking over it, restoring Health and reducing this Ability's Cooldown. Dr. Mundo also has significantly increased Health regeneration.
Dr. Mundo throws an infected bonesaw, dealing damage to the first enemy hit based on their current health and slowing them.
Dr. Mundo electrocutes himself, dealing persistent damage to nearby enemies and storing a portion of damage he takes. At the end of the duration or on Recast, Dr. Mundo deals a burst of damage to nearby enemies. If the burst hit an enemy, he heals a percentage of the stored damage.
Passive - Dr. Mundo gains bonus Attack Damage, increasing based on his missing Health. Active - Dr. Mundo slams his “medical” bag into an enemy, dealing additional damage based on his missing Health. If the enemy dies they are swatted away, dealing damage to enemies they pass through.
Dr. Mundo pumps himself with chemicals, instantly healing a percent of his missing Health. He then gains bonus Attack Damage and Move Speed, and regenerates a portion of his maximum Health over a long duration.

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.

Riot's ability text for Dr. Mundo describes healing or regeneration in HEART ZAPPER (ability 2), MAXIMUM DOSAGE (ultimate). 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 Dr. Mundo is, so read the full descriptions on this page.

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.
