Heather Underwood

Heather Underwood is a character in Kamen Rider Beetleborg. She is 18 years old, about the same age as Drew.

Personality
In Big Bad Beetleborgs & Beetleborgs Metallix, she was Drew's crush. No matter what, Drew could never tell Heather what he really felt.

Years later, Heather Underwood became a co-worker of Roland's at the Bistro La Salle. She was involved in the meteor crash seven years ago along with Drew McCormick. Due to the accident, her parents were killed. She believed that they were murdered by a person wearing a Rider Belt, but after a period of uncertainty she concludes that Drew, despite owning the belt, would never do something like that. After seeing Boron wear another belt & discovering that he was Roland Williams, she also began to doubt him. In the end, however, she decides to trust both of them as they have helped her so much. She carries a green crystal that originated from Area X, ground zero of the meteor crash. She seems to be able to talk with & read the emotions of inanimate objects, such as drawings & machines. She's quite clumsy & tends to zone out while working, resulting in complaints by customers. Through several mishaps & accidents, she was able to discover the identities of all the Riders besides Dragonborg.

During episode 20, the energy charge from the Hyper Zecter sent her along with Shadowborg to the edge of time & space. The Hyper Zecter later appeared in the normal dimension, showing one of Heather's drawings to Drew & Roland.

She reappeared during episode 23, being led away by Shadowborg, at the edge of time & space. She returns to the real world in episode 27 to defend Shadowborg from Hyper Beetleborg, stating that she no longer desires to live in the human world. Ultimately however, after a compelling speech by Drew saying that she will not be hated in the human world, even though she is a Worm, she abandons Shadowborg & returns to the human world. However, she is then attacked by Shadowborg. After being saved by Drew, she returns to an almost normal life, & begins making her own menu & dream of owning a restaurant come true. During the epilogue, she returns to her normal life in working at the Bistro.

As Worm
Sisyra Worm is Heather's alter ego; Sisyra Worm surfaced after Heather was in danger of being killed by Worms. Like Tanner, she is a Native who chose not to attack humanity.
