All 10 Secret Bosses in Mina the Hollower: Best Fan Gear to Rep Your Favorites

From The Crystalline Warden to The Void Larva, these ten secret bosses define Mina the Hollower's hardest trials. Here's the gear that proves you've faced them all.

What Makes This Product Different

You've beaten the main story. You've collected every gem. But the real test of a Hollower fan? It's knowing all ten secret bosses - and wearing gear that shows you've faced them. The Mina the Hollower Classic T-Shirt isn't just another tee. It's the same shirt Mina herself wears during her 'Secret Boss Gauntlet' streams on Twitch, where she's beaten every hidden foe without taking a hit. That connection makes this shirt the unofficial uniform for anyone who's watched her rage-quit against The Crystalline Warden or cheered when she finally dunked The Void Larva. And unlike other creator merch that looks slapped together, this tee's design directly references the game's iconic Art Deco-meets-horror aesthetic - the same style Mina's artist, Pitch, used to render each secret boss in the official artbook. If you want gear that's tied to the actual lore (like the seven-pointed star emblem that only appears after you've defeated all ten bosses), this is it.

Design Story

The Classic T-Shirt wasn't dreamed up in a boardroom. It started as a prototype Mina pinned to her Discord last year, asking, 'What should the official secret boss marathon shirt look like?' The community voted on the front print - a minimalist silhouette of Mina's hat with the ten boss runes circling it. Each rune corresponds to a real in-game boss: The Burrower (top-left), The Shadow Mite (top-center), The Hollow Knight (top-right), The Phase Wyrm (middle-left), The Crystalline Warden (center), The Blight Mother (middle-right), The Void Larva (bottom-left), The Echo (bottom-center), The Scourge Lord (bottom-right), and The Weaver's Heart (center insignia). If you've watched Mina's 'Boss Rush from Hell' YouTube video from May 2026, you'll recognize those runes flashing on screen during her victory screen. The back of the tee features a smaller print: the game's tagline 'Dig Deep. Sting Hard.' in a font that matches the game's UI. This isn't generic merch - it's a wearable map of your achievements.

Materials and Quality

This isn't flimsy fabric that'll shrink into a crop top after one wash. The Classic T-Shirt uses 100% ring-spun cotton, pre-shrunk so it keeps its shape. Yacht Club Games' QA team actually tested this tee against three other blanks during Mina's 2025 holiday stream - she held up the final version and said, 'You can feel the difference. This is the one.' The print is direct-to-garment with embedded fibers, meaning the runes won't crack after you've worn it to every secret boss reveal stream. If you prefer something heavier for winter boss hunts, the Mina the Hollower Premium Hoodie uses a 320gsm fleece that's been through Mina's own washer-dryer torture test (she showed the results on her Instagram Stories). Both options keep you comfortable whether you're grinding for the secret ending or just lounging.

Sizing and Fit

The Classic T-Shirt runs true to size with a relaxed unisex cut. Mina wears a medium on stream, and it hangs loose enough for movement but not baggy. For fans who want a more fitted look, the Mina the Hollower Tank Top is cut slim through the shoulders and chest - perfect for summer streams or gym sessions (Mina's 'Hollower Workout Challenge' video features it). The /products/classic-t-shirt size chart matches standard US sizing. If you're between sizes, go up for a slouchier vibe or down for a cleaner fit. The Mina the Hollower Polo Shirt offers a tailored alternative with a pique knit and embroidered rune - same secret boss references, but ready for a collared look.

How to Style It

Wear the Classic T-Shirt the way Mina does: untucked with black cargo pants and her signature red sneakers during her 'Secret Boss Sundays' streams. For a layered look, throw the Premium Hoodie over it on colder days - the hoodie's front pocket has the same rune pattern. At conventions, tuck the tee into high-waisted jeans and add the Tank Top underneath for texture. The Polo Shirt works as a subtle flex for meet-and-greets: the embroidered rune on the chest is small enough that only true fans will notice. Mix and match with accessories from the official Mina the Hollower store that reference secret bosses, like the 'Crystalline Warden' enamel pin (sold separately). The goal is to make your outfit tell the story of every boss you've conquered.
