Serena is Alien X's voice of love and compassion. She first appeared in X = Ben + 2. Professor Paradox is not allowed to be closer than 500 light years to her and Bellicus, or any Celestialsapien for that matter.
Serena looks like a female green human face with very realistic features. In Omniverse, her appearance is altered because of the new animation style.
Powers and Abilities
Due to Alien X not being able to do anything without a consensus from two of the three parts of its personality, Serena is relatively powerless on her own.
Serena can be terrifed by Toepick's face.
