Zennith wears a white dress with a black stripe in the middle of it. She has darkened lips.
In a flashback in Solitary Alignment, Zennith did not approve of Azmuth's irresponsible aspiration when creating Ascalon and desired to spend more time with him. Realizing Azmuth was obsessed with Ascalon, Zennith left and never returned. This led Azmuth to create the Omnitrix in hopes that she may notice his change in responsibility.

- Zennith's dress looks like Ben's shirt from the original series, only as a dress and with a thinner stripe.
