Hinox returns to the Zelda universe in Hyrule Warriors: Age of Calamity as a mini-boss. Fortunately, he is easier to topple now than in Breath of the Wild.
While he moves slowly, the Hinox has a lot of power and can rapidly drain hearts. It's important to keep moving during this battle and stay out of reach of the beast's arms.
The monster has a few attacks. The first is curling into a ball and rolling at you. Dodge out of the way and attack from behind to hammer away at his defense gauge until you can perform a weak-point smash.
Also, watch out for his ground pound. The move is strong but leaves him vulnerable. Be patient and attack when there's an opening.
Once you deal a significant amount of damage, Hinox becomes more aggressive and performs a flying sumo move. Activate Stasis when you see the prompt to easily dispatch the giant beast. The same tactic effectively takes down Hinox regardless of the mission.
