The Hinox Brothers are the Bosses of Hinox Mine and Bomb Storage, and the Mini-Bosses of Volcano and Fortress in Tri Force Heroes. They are a trio of Hinox siblings dressed in overalls and wearing helmets. Like the rest of their species, they throw Bombs as their method of attack. The Hinox wearing orange is named Li'l Hinox, the Hinox wearing purple is named Hinox the Elder, and the Hinox wearing red is named Hinox the Eldest.
In Hinox Mine, the Links initially only face Hinox the Eldest. The Hinox Brother is battled on moving mine carts that circle around the Boss Stage. The Eldest Brother will throw Bombs at the Links whenever their mine carts come close. To fight the Brother, the Links must grab the Bombs he throws over and throw them back into his mine cart, so that they will explode and damage him. The Hinox can be stunned momentarily with the Boomerang. Arrows shot from the Bow will also damage him, although the damage is significantly lesser than the Bombs. Hearts on the outer ledges of the stage can be collected with the Boomerang. After the Eldest Brother takes enough damage, he will reappear with Hinox the Elder, each riding their own mine cart. Both will throw Bombs at the Links simultaneously, and the pair are fought in the same manner as before. After one Hinox is defeated, he will fall to his knees and stop throwing Bombs, allowing the Links to focus their efforts on the one that remains.
In Bomb Storage, the Links face all three Brothers, but initially face Hinox the Eldest and Hinox the Elder. The Brothers appear from balconies on the other side of a gap and throw Bombs at the Links. As the gap is too wide for the Links to throw their Bombs at the two Brothers, the Links must instead use the Gust Jar to blow the Hinox' Bombs back onto their balconies and damage them. After both Hinox are defeated, the doors to their balconies will close, and another will open, revealing Li'l Hinox.
Li'l Hinox will rotate between the room's five balconies. He throws giant Bombs at the Links capable of huge explosions, which inflict heavy damage if any of the Links are unlucky enough to be caught in one. He then laughs for a few seconds before his door closes, and reappears on another balcony. The Bombs are too heavy for the Gust Jar to blow back; instead, one of the Links must place a smaller Bomb onto the floor for another Link to propel it into the Hinox's balcony using the Gust Jar. As the battle progresses, extra doors will open to empty balconies in an attempt to trick the Links, and Hardhat Beetles will also appear on the Links' platform to try to push them off, though these can be defeated for Hearts and Rupees. As the Hinox takes more damage, he will increase his speed and more doors will start to open at once. After taking enough hits, the final Hinox Brother will be defeated.
- "The youngest of the Hinox Brothers, Li’l Hinox actually happens to be the most pesky of the bunch. The Hinox Brothers love tossing Bombs furiously, but where Li’l Hinox differs is the size of the Bombs it likes tossing. Instead of the normal, small Bombs, Li’l Hinox will throw a massive, megaton Bomb. Just don’t stand too close, or you’ll get a face full of fire!" (Tri Force Heroes Player's Guide (Prima) pg. 20)
- "Hinox the Elder isn’t much different from a normal Hinox. The key differences are that it throws Bombs from a minecart and it throws them much faster than your normal Hinox." (Tri Force Heroes Player's Guide (Prima) pg. 20)
- "Hinox the Eldest is just like its younger brother, Hinox the Elder. You’ll face Hinox the Eldest while riding in a minecart. It loves throwing Bombs—perhaps you should follow suit?" (Tri Force Heroes Player's Guide (Prima) pg. 20)
