Nebula

Nebula appears in the two-part Silver Surfer episode "Learning Curve" voiced by Jennifer Dale. Nebula, like many before her, wants to gain knowledge from The Universal Library (Home of the Watchers). Because the motive of her search for knowledge is greed, she devolves into a creature known as a viral (a blob-like creature full of knowledge, but unable to act on it). The Silver Surfer needs help from the virals in order to penetrate a force field covering Zenn-La. After doing so, the Surfer has to help Zenn-La leave a dimension belonging to a being known as The Soul Hunter. During the escape, The Silver Surfer fails to save Shalla-Bal, for which he blames Nebula. He starts to blast her, but she is protected by Thanos' energy field (in the new history of the universe, Thanos is a peace seeker and resident of Zenn-La). One of the energy blasts penetrates the field, restoring Nebula to her humanoid form, and she takes her leave. Her final scripted appearance has her attempting a journey to Galactus' ship, because of the knowledge she recalled from her time as a viral. Unfortunately, no further scripts were written to explain this. Like many characters, Nebula was to make another appearance on the second season of the series. Eight episode scripts were written, but were never produced.
