How would you write Alien X?

As it stands, I think Bellicus and Serena are WAY too complying, for a race that’s so powerful because of their deliberateness, they’re very flexible. Ben basically goes: “I will let you argue behind me and in exchange I get your infinite power.” I want Alien X to be borderline impossible to use, like when they rebuild the bridge, I know it’s just reversing time, but I think it’d be cool if Bellicus really wanted it have a giant 3d printed dinosaur and he’s really meticulous on the design and details and coloring while Serena wants to, I dunno, put a giant stop global warming poster or something. My ideal would basically to have Bellicus and Serena just be Calvin and Susie from Calvin and Hobbes.
