Titan Triceratops

A giant three-horned herbivore far larger than the common frilled defenders, an armored battering ram crowned with horns longer than spears. A bull-titan in full charge can gore a war-elephant off its feet. Bull-titans hold a stretch of open plain against all comers and gather into a horn-out ring when the great predators close in; stubborn and unafraid, one will charge a creature far above its weight rather than yield a single step of ground.

Triple Horns: piercing, melee 10 ft, +3 to hit, 3d8+6 piercing. Goring Charge: after moving at least 20 ft it gores for an extra 3d6 and tosses a Large or smaller target 15 ft, knocking it prone on a failed Dex Quick save, cooldown 3 rounds.

Bone Frill: the great neck-frill shields its head and flanks and it cannot be flanked from the front. Unstoppable Bulk: too massive to be moved or knocked prone. Senses: Twilight Sight, Keen Smell.
