OLD drawing I did for  ElCid back in July 2018...

Something odd began happening to Singularity one day... her belly began to expand, growing rounder by the day! Unbeknownst to her or anyone else, the pocket universe housed within her body was expanding, but because of the growth distribution, Singularity came to one conclusion that she was pregnant! She had no idea how it could've happened, but she became convinced that she was going to be a mother, and she was absolutely excited. She began sitting out of more risky heroics and eating more, the inactivity and increased food intake naturally resulting in her becoming quite the fat universe-being indeed. Of course, remaining slim isn't a requirement for mobility when she can weightlessly float about and teleport, so Singularity remained happy as ever when she became a huge blob. And especially huge was that ever-growing tummy! At that point, her growth slowed to a stop. Despite the lack of new growth for quite some time after this, she continued to look forward to what would happen next, even as she went weeks and then months without any change to her belly's size. But even this didn't worry her!
