Kimoko

A petite Japanese-intelligence agent who briefs VALCom on the Vedic-Atlantean backstory of the Ultima Thule project and gains density-and-invulnerability powers from the Saucer radiation (#16) - powers that first triggered in the bathtub, dropping her through the floor and getting her evicted, so she becomes Z-Girl’s roommate. She bowls over the invulnerable Super Ficial! as a “human cannonball” (#17).
