No world can be truly hopeless if it contains this photo. It's one of several of unknown provenance circulating the internet. Han Solo rides to the Batcave to pick up Batman for a pleasant afternoon outing. They rest on the back of Swift Wind, the magical horse belonging to She-Ra from She-Ra: Princess of Power. You can see more photos in the series at Nerd Approved.
P.S. Now before I anger any He-Man and the Masters of the Universe fans, let me say this: yes, my headline is probably incorrect. Swift Wind is not, strictly speaking, a flying unicorn. Nor is he a pegasus, let alone an alicorn. He is a horse with magical transformative powers. Unfortunately, I am unaware of any word that adequately describes a horse that transforms into such a creature, rather than one that is naturally-occurring in this form.
