After widespread fan requests, Marvel Rivals finally added skin customisation in Season 2, but it came with a catch. You can't just pick any old colour you want and slap it onto your skin. Season 3's ultimate ability VFX is similarly restrictive. Instead, you need to get unstable molecules to buy colour palettes and ultimate effects. Alongside chrono tokens, costume coins, and various premium currencies, this item is yet another thing to keep track of.
On the bright side, the new Marvel Rivals ultimate customisation and further additions to the costume customisation options do look great. These features haven't been rolled out to every character or skin quite yet—just a handful of the most popular faces that you can likely guess right away—but more are coming in the future. As such, you'll want as many unstable molecules as possible.
