One possible storyline could be that Starscream and Bumblebee are forced to team up during a crisis on Cybertron. Maybe there's a new threat that neither of them can handle alone, so they have to put aside their differences. For example, a powerful alien force arrives and starts attacking the Autobots and Decepticons alike. Starscream, being the opportunist he is, realizes that only by working with Bumblebee can he survive and perhaps gain some advantage later. Bumblebee, on the other hand, is hesitant at first but then sees the bigger picture.
A time - travel plot could also be interesting. They could be sent back in time to an era when Cybertron was in a different state. There, they might meet younger versions of themselves or other important Transformers. This could change their perspective on their own history and relationship, and they might come back to the present with a new outlook on their rivalry.
Harry Potter himself is a likely candidate. Given his heroic nature and penchant for getting involved in dangerous situations, he might be the one to first encounter Starscream. His experience with facing dark wizards could give him some skills to deal with the unpredictable Starscream.
Well, Bumblebee could try to escape by building a device from the scraps he finds in Megatron's place. He's a resourceful Autobot. He might be able to create a communication device to call for help or a weapon to fight his way out. He could also look for any weaknesses in Megatron's security. Maybe there's a power source that, if disrupted, would open all the doors. Bumblebee could also try to form an alliance with some of the other captives or minions in Megatron's lair who might be disgruntled and want to escape as well.
