[SPOILERS] How to unlock every B-Skin

Overview

How to unlock every B-Skin for every character, ordered from what I think is the easiest to the hardest.

1. Eyes’ B-Skin

The easiest B-Skin to get. Simply play as Eyes, grab an explosive weapon (preferably a grenade launcher), get to the sewers, find the manhole, and bust it open with an explosion. You are now in the Pizza Sewers, and Eyes can now don 3-D glasses!

2. Crystal’s B-Skin

Pretty simple, although a bit luck-based. All you have to do is play as Crystal, get a crown in 3-2, hope for a cursed weapon chest, pick the cursed weapon up, and head to the Crystal Caves. Because you now have a cursed weapon, the Crystal Caves becomes cursed as well! You can now play as cheddar cheese a yellow, blockier Crystal.

3. Robot’s B-Skin

All you need to do is find a hyper weapon as Robot (I.E. Hyper Rifle, Hyper Slugger, etc.), eat it, and you can now play as Robot with blue I.D.P.D. armor.

4. Y.V.’s B-Skin

Simple, although tedious, you have to get the screwdriver with all 12 characters, go to Y.V.’s Mansion, and store a golden weapon in your inventory (take it to the next level). Probably the most underwhelming B-Skin, Y.V. can now float and shoot with his eye closed. Yaaaay…

5. Plant’s B-Skin

Here’s where things get challenging. You have to defeat the Nuclear Throne as Plant in under 10 minutes. You do not have to loop (though it will still unlock the achievement), and you can take shortcuts, so take full advantage of Oasis! Upon achieving this goal, Plant blooms!

6. Rebel’s B-Skin

Get to loop 1 and defeat the Ballmama, easier said than done. Make sure you have Throne Butt, or else the fight’s probably gonna be quite harder. Upon blowing up the poison-spewing abomination, Rebel can now wear a fluffy coat, and will button it up when entering the Frozen City.

7. Horror’s B-Skin

All you have to do is play through the game and loop as Horror, then defeat the Hyper Crystal in the Crystal Caves (or the cursed variant). Horror can then become an electric portal-esque monster!

8. Steroids’ B-Skin

Here’s where things start to get really hard. What you have to do is loop as Steroids, get to the Labs, and defeat the Technomancer! Assuming you survive the horde of raving freaks, Steroids gets a muscle shirt, a tan, and a sweatband.

9. Fish’s B-Skin

Quite an amazing feat, loop with all 12 characters (that includes Melting, dun dun dun)! Upon doing this, Fish will look less healthy. Donning an eyepatch, a toothpick, and some stubble, Fish becomes Big Bass!

10. Chicken’s B-Skin

Extremely hard and patience-trying, we have the unlock method for Chicken’s B-Skin. Oh boy. First, you must make it to loop 2 and unlock hardmode. Then select hardmode from the title screen, and play as Chicken. Make it to 2-1 and you’ve got yourself the B-Skin. Much easier said than done…

11. Melting’s B-Skin

You have to be perfect. You have to make it to the Nuclear Throne as Melting without Rhino Skin, nor Strong Spirit. One hit, you’re done, try again. Throne Butt helps a ton, and will probably save you from a lot of things that would one-hit kill you. Upon accomplishing this, Melting will now become Melted, complete with teenage angst.

12. Rogue’s B-Skin

This is the hardest B-Skin to get. It’s ridiculous. You have to loop as Rogue, hitch-hike on an I.D.P.D. Van, make it to the I.D.P.D. Headquarters, and defeat the Captain. This is extremely hard, since the Captain is basically a combination of the Nuclear Throne, Big Bandit, and a Touhou boss. If you manage to do this (you ultimate beast), Rogue will become Elite!
