The Genesis Unit.

In another part of the city, 

Pillars of smoke and fire billowed into the sky as explosions rattled the city's core. The air was thick with the acrid stench of burning fuel, mixed with the sharp, metallic tang of scorched metal. Buildings groaned and cracked, their foundations quaking under the relentless assault.

A massive, twisted creature loomed in the heart of the chaos, its enormous body coiling and thrashing as it tore through the streets. Each movement sent shockwaves rippling through the ground. The sound of its roars echoed off the walls, deep and guttural, vibrating the air around it.
