Redemption can be a theme. Metal Sonic, often seen as a villain, can be redeemed through his interactions with Amy. Her positive attitude and belief in the good in others can gradually change Metal Sonic's cold - hearted programming.
The theme of acceptance is also popular. Amy has to accept Metal Sonic for what he is, a machine created for certain purposes, and Metal Sonic may need to accept Amy's emotions and her way of seeing the world. This mutual acceptance can lead to a deep and unique relationship in the fanfiction.
Well, there are several. A prevalent theme is the clash of different natures. Metal Sonic's mechanical and often emotionless self against Amy Rose's passionate and emotional being. This can lead to themes of understanding and learning from one another. Another theme is the idea of an unlikely alliance. They might form an alliance against a greater threat in the Sonic world, and during this alliance, feelings start to develop. And sometimes, there are themes of sacrifice, where one of them might be willing to sacrifice for the other, which adds a lot of drama and depth to the fanfiction.

One common theme is friendship. Sonic and Sonic (even if they are different versions) often form a unique bond, and their friendship with Amy is explored in different ways. It could be about how they support each other through tough times.
For Amy, she could become more understanding of the 'evil' or opposing side. Instead of just seeing Metal Sonic as a bad guy, she might learn to look deeper into his existence as a creation. This could make her more empathetic in general.
