>>113830412In-universe Ben does need to consult Bellicus and Serena to do anything, otherwise, they'll bicker for eternity as Ben is the voice of reason in their Trio
He only gets full control of Alien X about two and a half times in the series.
He's not omnipotent as there is an entire race of Celestial Sapiens, they were going to destroy the universe since Ben recreated it without authorization.
He almost got his ass kicked by the Galactic Gladiator he clutched it out just in time.
The most important thing about Alien X is the fact that he is NOT an instant win button or powerlevel fuel, He's a hyper durable reality warper with the catch of having to convince Bellicus and Serena of doing anything while real time happens outside his frozen body.
The Alien that absorbs the Big Bang and saves all of spacetime is Feedback, Not Alien X.
