Marrowbreach

A large apex predator that hunts in a symbiotic partnership with the Houndgar. The Marrowbreach is an ambush hunter — it relies on its Houndgar companions to dazzle and disorient prey with a bright bioluminescent flash, then strikes. With 1,000 HP and a top speed of 5 m/s, a cornered Marrowbreach is one of the most dangerous non-leviathan encounters in the game.

Lore

The Marrowbreach / Houndgar hunting partnership is one of the most sophisticated predator relationships on planet Zezura. The Houndgar does not benefit directly from the kill — its role appears to be purely cooperative, suggesting a level of symbiosis that raises questions about Zezuran evolutionary biology.
