Who's Who in the DC Universe 1 Page 20 - Kono by Kevin Maguire

Published 1990.
Kono also is known for her short, obnoxious, uppity, brawling, and always spoiling for a fight attitude. Her background and her race's propensity at warfare, Kono learned self defense at an early age.
Here Kono demonstrates her power to make herself intangible or to make things so dense that they collapse under their own weight.
Kono sometimes is unable to control her clothing density while using her powers and sometimes bares her anatomy. However since she is by no means modest, it doesn't bother her.
