Serena is Alien X's voice of love and compassion.


In Alien Force and Ultimate Alien, Serena looked like a female green human face with very realistic features.

In Omniverse, she has eyelashes, eyebrows and a more humanoid nose.


Serena is a moral manifestation within Alien X together with counterparts Bellicus and Ben Tennyson. She represents the voice of love and compassion and thus is often calm and peaceful. Unlike her counterpart Bellicus, she is sometimes (though not fully) intrigued by Ben Tennyson's will and ideas for Alien X; this suspends unanimous agreement between the three parties. She is generally naive, sensitive and emotional, and is often seen arguing with Bellicus about what is best to do. Despite this, it takes slightly less persuasion to convince Serena of ideas than with Bellicus.


Serena first appeared in the episode X = Ben + 2 when Ben transformed into Alien X, and Ben quickly discovered he was locked inside the form because of the eternal debates between the two entities who control its body, Serena and Bellicus. Professor Paradox is not allowed to be closer than 500 light years to her and Bellicus, or any Celestialsapien for that matter.

Powers and Abilities

Serena, along with Bellicus (and by extension Ben), has the ability to warp reality.


Due to Alien X not being able to do anything without a consensus from two of the three parts (in Omniverse, all three) of its personality, Serena is relatively powerless on her own.

Serena, like all Celestialsapien personalities, can be terrified by Toepick's face. [DJW 1]
