Fornite Chapter 2 Season 4 has a Battle Pass loaded with awesome Marvel skins. As you progress through the levels you will unlock Thor, She-Hulk, Iron Man and many more. On top of that, each skin has style variants that you can unlock, including very special variants called the Foil skins.
Thor's Holo Foil skin is commonly referred to as Rainbow Thor, but you'll need to put in a lot of work to unlock this awesome skin. First, you'll need the Battle Pass which will cost you 950 V-Bucks, as you can't get the base Thor skin without it. After that, you'll need to start leveling up, maxing out your Battle Pass, and unlocking all of the items in it. Only after reaching level 100 will you be able to start unlocking the foil skins.
There are three different foil skin variants for each of the Battle Pass heroes: Silver, Gold, and Holo. The Holo skin is what people call Rainbow Thor.
- Silver – 105
- Golden – 145
- Holo - 185
To unlock the Holo skin, you'll need to reach Tier 185 on the Battle Pass, which will take some work. On average, you'll need to level up about two-and-a-half levels each day in Season 4 if you want to unlock all of the Foil skin variants in the Battle Pass, though getting access to the Rainbow Thor skin takes a little less work.
And that's it, it will take some dedicated play during Season 4, but as long as you're averaging around two and a half levels a day, you should get there before the season ends on November 30.
