The trees of the forest were crushed by the threads of the gigantic tank, making a hellish noise composed of sickening cracks and snaps that utterly crushed the peace of the area beneath its heel. But the lone pilot of the steel monster did not care about the treasures of nature, nor the humans that fled from her invincible monster. She only cared about her enemy, the enemy she had been chasing for hundreds of years now, the enemy that she held responsible for her own state. After all, it was his fault that she almost died, and the scientist had to use a yet-untested procedure to hook her up to life support and make her more machine than human. Sure, she gained immortality, not to mention eternal youth because of it, but that did not excuse his actions. She hated him more than ever, so when she finally found a clue to his location, she followed it, not caring about the rest of the world.
The tank she was riding in was also his invention; she hijacked it with the help of her fanatic followers when it was being tested, then turned it into her personal war machine that nothing could stop. After all, it was the size of an aircraft carrier, had the armour of a nuclear shelter and was completely self-sufficient. It could cross any terrain, it carried dozens of small drones for defending itself, but its most useful feature was its absolutely terrifying size that made everybody think twice about attacking it. Just the presence of the tank was enough to send most militaries fleeing, especially after they have seen what it was capable of. It rolled from country to country, destroying everything in its path and causing more ecological damage than what humanity caused during its existence.
But for her, none of that mattered. She only wanted to take revenge on him, to make him pay for his crimes, to crucify him, gut him and hang him at the same time so he suffered as much as possible, to make his life a living hell. She wanted payback. So she steered her tank towards the direction she thought he was and increased the speed of this moving fortress, thus cracking the ground and almost crushing the Earth's crust. He would not escape her wrath.
