Threat Assessment

By taking his bat-gland formula, Kirk Langstrom can transform himself into a bat-like creature. By taking an antidote or if the bat-gland formula wears off, he can return to human form.

As Man-Bat, his strength, agility and endurance are all enhanced to superhuman levels. Kirk possesses an extra set of digits that form leathery bat wings that allow him to fly, super-sensitive hearing, and a natural sonar. He emits high-pitched sound waves and can hear the echoes they make when they bounce off nearby objects, enabling Man-Bat to navigate perfectly in pitch black darkness.

If in Man-Bat form for a prolonged time, he loses control over his animalistic side and works purely on instinct, making him prone to harm friend and foe alike.
