Bellicus is not very concerned about others‚ having no problem with letting billions die as he believes they've probably got it coming․ However‚ he was interested in discussing whether or not to save the dinosaurs from extinction․ Compared to Serena‚ Bellicus is much less welcoming to Ben‚ wanting to ignore him and set him on fire․ Bellicus can be quite argumentative with Serena‚ but can become very angry towards someone if they upset her․ Bellicus is very stern with Paradox‚ due to a treaty between him and the Celestialsapiens for Paradox to stay at least 500 lightyears away from them․ Bellicus has shown that he will back down to Ben when Ben reacts angrily to him‚ such as when Ben lost his temper and demanded to be allowed to change aliens‚ saying he has nine other aliens that can do the job better than he and Serena can․ In order for Alien X to perform any action‚ including simple movement and transforming back‚ two out of three or all of his present personalities must agree to do so‚ unless they decide that one personality can have control on their own․ As Serena and Bellicus aren't interested in dealing with present affairs and want to finish past ones that weren't possible to deal with without Ben‚ it was initially very difficult to get them to agree on any present task․
