- KitKat - as a Flowerette- One of the two villains created in the computer world by Terracotta. Skilled martial artist, their dual attacks proved too much for even Krystala, actually beating her into submission.
- Jeffrey Santos - as Likido- A man who has the ability to transform into any form of liquid, and can turn things into liquid. Has repeatedly evaded Krystala because of this ability, even discovering her secret identity.
- Gabe Mercado - as Gravigat- A man who can manipulate gravity. Despite seemingly incompetent at first glance (which may have led Krystala into thinking that she could easily beat him), his powers afford him a tremendous advantage over many foes. In fact, he humiliated Krystala on their first encounter where, after Krystala made her presence known to Gravigat while still hovering in mid-air, he lessened the gravity centered around the heroine's location where she was still hovering, this caused her to lose control over her flight powers, preventing her from landing, trapping her in the air. Gravigat is notably the first villain to be able to use Krystala's powers against her, leaving her defenseless as he made his getaway. The gravity around Krystala only returned to normal after Gravigat left the vicinity. Unfortunately, by this time she had also canceled her own levitation as she attempted to fight the opposing force of anti-gravity that was keeping her stuck unsupported in the air a while back, she fell face-first to the floor
- Desiree del Valle - as Luminax- A woman who has the ability to turn into light, manipulate light, and attack with light (ex; light blast, lasers that shoot out of her eyes).
