Perhaps Lucifer could possess one of the Transformers. This would give him a powerful physical form to interact with the human world in a different way. The Autobots would have to figure out how to expel Lucifer from their friend without destroying them. And the Decepticons might see this as an opportunity to team up with Lucifer - possessed Transformer to gain an edge in their fight against the Autobots.
One idea could be that Lucifer, with his charm and manipulative skills, gets involved in the power struggles among the Autobots and Decepticons. He might try to use their war for his own amusement or to gain some sort of power. For example, he could offer a deal to Megatron to help him defeat the Autobots in exchange for something valuable in the underworld.
Another idea is that the Transformers end up in Lucifer's realm. The Autobots might be on a mission to retrieve something that was lost there or to stop the Decepticons from making a deal with Lucifer. The culture clash between the mechanical beings and the demons would be really interesting to explore. How would the Transformers react to the chaotic and often immoral nature of Lucifer's world?
