I know not if you remember me, but I had the 'pleasure' of being a 'special guest' of your father, Thanos. My stay included the delightful amenities of copious amounts of torture, a dingy blood stained cell, and having my thoughts coerced into believing and doing things that I would not ordinarily do. I tend to work for myself or on behalf of the royal house of Asgard, and not at the convenience of any other being. As you can imagine, as a Prince, this was a severe inconvenience and a rather insulting experience.
Let me set one thing straight. I am a God. If you dare mention my time as a prisoner to anyone, I will make it my life's sole purpose to kill you.
Now that we've cleared the air of that general unpleasantness?
As a potential peace offering in exchange for your discretion, I can offer you an illusion. One that will let you pass among the mortals of this realm as one of them, but retain your usual visage to all those who know you personally. If you so wish it? If not, then I shall go back to my tasks and eating small square bites of cake from Paris.
