In lieu of hearing like the average person, Langstrom could only see, feel, and smell to find his way around, due to having become deaf years back. His whole life, dedicated to curing his ailment, had been for nothing. He'd become the very thing he studied -- a bat.

The large bat-hybrid skittered around Gotham's dark catacombs, leathery wings flapping noisily down the shadowy corridors. Everyday was the same -- wake, hunt, fly, rinse, repeat. He lived like an animal, and he loathed it. He longed desperately for his humanity back.

Langstrom instantly caught the scent of something new in the catacombs, a fresh, metallic scent... blood. He pivoted in the air and began to track the scent, large wings fluttering as he moved with practiced speed. He relied on scent to find them, unable to hear.

Then, he saw them. A human, in his catacombs, so far from the public and injured... Man Bat's interest was piqued. The animalistic man swooped down and landed in front of the newcomer, talons gripping the ground. He instantly noted how small the human was compared to his large, bat-like body. The creature cocked his head to the side, sweeping an untrusting eye across the person before them, fangs chittering cautiously. Langstrom knew he looked terrifying, a large monstrous creature, far from the scientist he once was.
