Serena (Ben 10)

Serena is Alien X's voice of love and compassion. She first appeared in X = Ben + 2.

Appearance
Serena looks like a female green human face with very realistic features. In Omniverse, she has eyelashes, eyebrows and a more humanoid nose.

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

Weaknesses
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 can be terrified by Toepick's face.

Trivia

 * In X = Ben + 2, Serena said she thinks Pluto should have been a planet instead of a dwarf planet. She even asked Ben to vote on it.
