It could also develop if they face some sort of internal conflict. Say, Silverbolt has to choose between his loyalty to his group and his feelings for Blackarachnia. And Blackarachnia has to decide if she can trust Silverbolt. Through these conflicts and how they resolve them, their relationship can grow in complex ways. Well, like in a situation where Silverbolt defends Blackarachnia from an unjust accusation from his comrades. This could make Blackarachnia question her view of him and start to open up to him more. And for Silverbolt, he might see that she is more than just her actions and start to see the potential for good in her.
Another way would be if Blackarachnia had a change of heart earlier in the story. Instead of being so focused on her own goals, she could be more open to Silverbolt's ideas. This could lead to a quicker and more harmonious relationship development, with them sharing their knowledge and skills to achieve common goals.
One plot idea could be that Blackarachnia and Silverbolt are forced to team up on a mission in a dangerous part of the Beast Wars world. They initially clash due to their different personalities and allegiances but gradually come to understand and respect each other.
Perhaps they get transported to an alternate dimension where they have to rely on each other to survive. In this new place, they find out things about their pasts that they never knew before. Silverbolt might learn about Blackarachnia's reasons for being the way she is, and she might see that he is not just a naive goody - two - shoes. This could lead to a deeper understanding and a possible change in their relationship.
One idea could be exploring Blackarachnia's past before the Beast Wars. Maybe she had a different life or purpose that got derailed. Another could be a story where she forms an unlikely alliance with one of the Maximals, like Cheetor, and they have to work together to overcome a common threat. Or perhaps a fanfic that delves into her relationship with other Predacons, like how she might be trying to gain more power within their ranks while also dealing with her own internal conflicts.
Optimus Primal would make for a great pairing. Their opposing allegiances would add a lot of tension to the story. Blackarachnia could be trying to outwit Primal at every turn, or perhaps there could be a situation where they have to work together reluctantly for the greater good. Silverbolt is also a good choice. His noble nature could be a foil to her more self - serving ways, and there could be a love - hate relationship developing between them.
I really like 'The New Alliances' fanfiction. It takes the concept of the Beast Wars and flips it on its head by creating new alliances between different factions. There are some unexpected pairings of characters that work surprisingly well. The plot is full of twists and turns, keeping you on the edge of your seat throughout the story.
A popular fanfiction is 'Rampage in a New World'. In this story, Rampage is transported to a different dimension where he has to adapt. It's interesting to see how his violent nature plays out in this new and unfamiliar setting. There are some great action scenes and character development throughout.
One great 'Beast Wars Cheetor' fanfiction is 'Cheetor's Adventure'. It really delves into Cheetor's growth and his relationships within the Beast Wars. It shows his struggle to adapt to new situations and how he overcomes challenges. Another one could be 'Cheetor and the Lost Artifact'. This fanfic takes Cheetor on a quest to find a powerful artifact, full of action and interesting character interactions.
