What carries over between seasons in Marvel Rivals?
Your Battle Pass never expires once you own it, your Units and Lattice stay in your account forever, and your rank drops rather than wipes at reset — but Chrono Tokens don't carry over unless you paid real money for them, and you can't buy a past season's premium pass after it's ended.
Rank, currency and Battle Pass all survive a season change differently — here's which ones actually reset.
The Battle Pass is the one that surprises people: it doesn't expire. Every past season's pass stays on your account and you can keep leveling it at your own pace long after that season is over, as long as you already owned the premium tier before it ended. What you can't do is buy a season's premium pass retroactively — once a season closes, its pass is locked to whoever already had it.
Rank resets, but it's a demotion, not a wipe. Marvel Rivals resets competitive twice inside a single season cycle: once when a full new season starts, and again — more lightly — when the mid-season update lands (Season 9.5 is one of those mid-season resets). Either way you drop several divisions below where you finished, not back to the bottom, and season-end cosmetic rewards are still handed out based on the highest rank you reached, even if you'd already been demoted off it by the time the season closed.
Units and Lattice never expire. Units are the free currency you earn from missions and the Battle Pass; Lattice is the premium one, bought with real money or earned through the pass, and it converts to Units at a 1:1 rate. Both sit in your account indefinitely — there's no season clock on either.
Chrono Tokens are the one currency that doesn't carry over. They're what levels up the current Battle Pass, and they reset to zero at the start of the next season — with one exception: any Chrono Tokens you bought outright with real money or Lattice stick around instead of disappearing. Free tokens earned by playing don't get that protection.
Everything you've already unlocked — skins, nameplates, sprays, hero costumes — stays unlocked. Seasons change what you can earn next, not what you've already banked.
