#0042 Golbat -- Pokedex Series (Patreon)

"Once it strikes, it will not stop draining energy from the victim even if it gets too heavy to fly. It attacks in a stealthy manner, without warning. Its sharp fangs are used to bite and suck blood. Bites its prey and feeds on the victim's energy. Its own blood type changes to that of its victim." -- Pokemon RBYSt
