Fanfiction about an Ice Age human woman and her interactions with human men (excluding any form of rape content).

A romantic relationship could be based on shared dreams. Maybe they both want to explore a new, uncharted area of their Ice Age world. They set out on an adventure together, facing the challenges of the cold and wild animals as a couple. Their love grows as they rely on each other for survival.

She would likely have long, flowing hair, perhaps a golden color like the sun, to represent her divine origin. Her eyes could be a bright, piercing blue or amber, full of an otherworldly intelligence. She would have a graceful figure, with a certain poise in her stance that makes her seem both approachable and yet somewhat ethereal.

One interesting story could be that in human form, Kyubey is a student in a high school. He tries to secretly recruit girls for the magical girl system without them realizing his true identity at first. He befriends a group of girls who are interested in the supernatural, and as the story unfolds, they start to suspect something strange about him.

In a Transformers Prime fanfiction, a human could befriend a Decepticon who is disillusioned with the evil ways of their faction. Together, they try to find a way to bring peace between the Autobots and Decepticons. This would involve many challenges as both sides are distrustful of the other. The human's unique perspective might be the key to making it all work.

One idea could be a story about a human from the Ice Age who discovers a hidden cave filled with ancient markings that lead to a secret power. Another could be a love story between two humans from different tribes during the Ice Age. Or perhaps a story of a human's journey to find a rare herb that can cure a deadly disease spreading in his tribe.

Maybe the human baby is a special child with some kind of unique ability. In the Ice Age setting, this ability could be related to communicating with animals. So the baby uses this power to bring different animal species together to form an alliance against a common threat, like a large flood or a group of extremely aggressive and territorial creatures.

For the human baby, you can give it distinct features like a curious nature. Maybe it has big, bright eyes that seem to hold a lot of wonder. For the animal characters, like the sloth Sid, you could make them have their own quirks. For example, a woolly rhino could be really clumsy but with a heart of gold, always accidentally causing a bit of chaos but meaning well when it comes to protecting the baby.

A lesser - known but really engaging fanfiction is 'Kurama: Human Form Unveiled'. It focuses on the mystery surrounding Kurama's human form and how it affects his interactions with other characters. The author does a great job of building up the tension and intrigue as the story progresses.

There's also 'Sonic and Amy: High School Years'. In this fanfiction, they are high school students. It shows how Sonic's speed is translated into his athletic abilities at school, while Amy is part of the art club. It's a really cute take on their characters in human form, with lots of typical high - school drama and budding romance.
