Weaknesses
Despite his great power, Alien X has weaknesses. The biggest weakness is the two personalities of Alien X; Bellicus, the voice of rage and aggression and Serena, the voice of love and compassion. The reason is because for Alien X to perform any action the two personalities must both agree to what would be the best action but because they are two different personalities it is difficult for them to agree on one thing and also to focus on one thing. This makes Alien X completely immobile and vulnerable until a decision has been made. According to Ben, Alien X is also vulnerable to having his power stolen such as when Ben refused to transform into Alien X when due to Michael Morningstar (Darkstar) draining his energy. When Ben managed to utilize Alien X's power by having the two personalities argue in peace, the only weakness he had was a lack of imagination. Another weakness is where he can also be vulnerable when fighting with other Celestialsapians, this is shown when the Galactic Gladiator was able to harm Alien X with ease. and according to Derrick J.Wyatt, Alien X is unable to survive on planet Anur Vladias.
