A member of the
Fatal Five.
Chi Tsan of Earth is the real name of the villain Caress.
Unsatisfied with what could be gained with the wealth her
family possessed, Chi Tsan took to a life of theft to get what
she wanted. Having studied martial arts, Chi Tsan became a
mercenary. She took a mission of the Khunds in exchange
for having Khundian technology give her greater power. Increasing
the strength in her arms and her ability to grip, the Khunds
also mutated Chi Tsan's glandular system to give her an acid touch
which was capable of burning through anything organic.
When the Emerald Empress was reforming the Fatal Five after
the loss of Tharok and Validus, she approached Caress and
offered her a place in the group. This put Caress in direct
conflict with the Legion of Super-Heroes.
