A massive, horrifying jaguar fused with a zombie, towering like a mountain

A massive, horrifying jaguar fused with a zombie, towering like a mountain, its body brutally affected by a virus that has left it in a state of decayed, monstrous terror. The creature's flesh is rotting, with exposed bones and tattered skin hanging from its muscular frame. Its eyes glow with an eerie, sickly green light, and its mane is tangled and matted with blood. The lion's teeth are jagged and broken, yet still sharp enough to tear through anything in its path. It stands menacingly in a desolate landscape at dawn, where the sky is a blend of ominous red and orange, casting long, dark shadows that make the scene even more terrifying. The air is thick with the stench of decay, and the ground beneath the lion is cracked and barren, as if scorched by the presence of this nightmarish creature. The dawn light makes the scene feel like judgment day, amplifying the dread and horror of this apocalyptic moment.
