Favour timeline — who owns each window

StageFavouredWhy
Level 1Even / skillBoth champions are level 1 with minimal threat — Mundo's Q has percent-HP poke range but you can avoid it by hugging the wave edge; neither side has a kill pattern yet.
Level 2Even / skillYour Q gives you an escape option but your damage is still too low to complete a kill combo before his passive regeneration undoes the trade.
Level 3Dr. MundoHeart Zapper's burst fires the moment you close range — your Frost-stack pattern requires two W strikes to land before E stuns, but his W damage and heal land in the same instant your engage does, winning the exchange.
Levels 4-5Dr. MundoHis percent-HP Q keeps stripping your Permafrost passive off at range, he outheals your stun damage, and you have no item to make the CC chain hurt enough — he controls the pace completely across these two levels.
Level 6Even / skillGlacial Prison finally gives you a ranged kill threat: throw R from outside his Q range, chain E stun, and request jungle follow-up before Maximum Dosage renders him unkillable.
First itemDr. MundoHis first item lands with Heartsteel stacks already banked from absorbing your poke — his HP pool now makes your CC chain a speed bump rather than a kill window, and his Q poke percentage scales with that HP.
Two+ itemsEven / skillBoth tanks are scaling into teamfight assets — your R can decide an objective fight across the map, so the lane 1v1 verdict is irrelevant as long as your CC lands where it matters.

Early game (levels 1–5)

At level 1 take W and hit the wave — you have no kill threat and neither does he, but his Q cleaver already deals percent-current-HP magic damage that strips your passive Permafrost armor before you can do anything. Hug the edge of minion range and let your wave freeze near your tower; a freeze here denies him plate gold while keeping his Q from reaching you on cooldown. Do not auto-attack him to try to stack Frost — his Q has longer effective range than your autos at level 1, and every trade you force lets his passive regen undo the damage before your W double-strike completes.
