Bio: When Chappell was in charge of Bane’s health, he derived
from him the serum known as “venom” and created a hot new steroid drug
for teens: “slappers.”
After Batman and Bruce Wayne figured out who was behind the slappers,
Batman went to go take Chappell down. After having too many of the
Slappers stick to his body, Chappell overdosed and became comatose. |
