Rena Ayers

Rena Ayers/Uca Worm is the first executive leader Worm assuming the form of Rena Ayers, a woman whose childhood dream was to sing in an opera.

As Human
The original Rena was a talented singer with a kind heart that wanted to help people. Believing herself to be Rena, she chases after her dream of being an opera singer until her Worm persona eventually resurfaced. She is able to sing one more requiem for Jay on stage, expressing her gratitude to him.

As Worm
Her true form is Uca Worm, the first executive Worm. A cruel & clever planner, she is the one who ordered a Worm to capture (or kill) Jo. In Worm form, she is very powerful & on her first debut, she defeated both Hornix & Dragonborg. She is also the only Worm to "truly" defeat McCormick & make him involuntarily power down. Soon after, she discovers the existence of the Hyper Zecter & attempts to retrieve it after she shoved Susanna off a building.
