I've had an idea for the first boss in my 2D femboy sidescroller. His name is Amber the Femboy. The scientists from the femboy lab sent him to keep track of Luna after he escaped. He has longer and thinner legs than Luna, which allows him to run faster. He also has special rainbow socks that allow him to run even faster.

When Luna escaped from the femboy lab, he was wearing the wrong pair of femboy socks, causing him to run slower than he normally would. When he spots Amber, he starts chasing him so he can steal his rainbow socks.

The boss fight consists of clearing the level under a time limit so that Luna can catch Amber and steal his rainbow socks. When he catches him, he wraps his powerful thighs around Amber until he passes out and then steals his socks, giving him a speed boost and making the rest of the game even more fast paced and challenging.
