Terra

She's powerful and will be able to help out a lot. You type in the commands and prepare to teleport her onto the ship. You pick a time when she is at her worst emotionally. You normally wouldn't do this, but you need to convince her to help at any cost. When she arrives, you see she has modest C-cup breasts but a rather large butt that is firm with muscle.

She looks around in confusion and shock, "What?! Where am I?" You approach her in an effort to calm her down, but your new stature certainly intimidates her. "I know my appearance must scare you, but I can assure you I don't plan to hurt you. I'm trying to save the multiverse, and I need your help to do so."

Terra is shocked at this, "What? Hold on, slow down. You bring me to . . . wherever we are, and tell me that you need my help to save the multiverse? Do you really expect me to believe this?" In response to her question you type something into the controls and start to show her scenes from several universes, she goes slack jawed at it in an instant. You look at her, "As you can tell their are many universes out there, and I need your help to stop a create that will . . . well you may want to sit down."

You explain the situation to her, the current threat and the part you play in it, and she is even more shocked by it. "What!? So, this thing will try to merge with every world and continue to grow stronger?" You only nod your head in confirmation, "Yes. The only way I can stop it is to . . . unfortunately conquer these world's before it can fuse with them." This catches her by surprise, "What? Why do you need to conquer them? Can't you simply warn them?" You shake your head, "No. That simply won't work. The heroes likely won't be able to stop it, maybe repel it for a time but not kill it. In order to kill it you'd need to have the power of a god, and I know a way to achieve this."

She looks at you perplexed and worried, "How?" You get ready for her reaction, "By having sex I can power the ship and become more powerful. I know it sounds odd but that's how they designed it." She freaks out as you feared, "What? Is that why you brought me here to be some -" You stop her as you explain, "No, I brought you here to help me I have an army but I can't lead them alone. I need somebody to also issue commands to them as well, and I want that to be you."

She looks down a bit and asks "Why me?" You give her the best response you can, "Besides how powerful you are I think your experience could be very beneficial in the decision making with my army. You know both sides, good and evil, very well as you've interacted slot with both. Though, I won't **** you to do this. If you want I can drop you off wherever you want in your world, or even another world. Once the ship has gathered enough power of course, but I won't make you do anything. This is your choice after all. So, what do you say?"
