Good character development. It should show how Ultra Magnus and Rodimus grow throughout the story, whether it's in their relationship or as individuals.
At first, they might seem like an unlikely pair. However, as they face various challenges together, their relationship can grow into one of mutual respect. Rodimus may come to admire Ultra Magnus' discipline, and Ultra Magnus may learn to appreciate Rodimus' creativity and courage. They could also have a mentor - mentee type of relationship, with Ultra Magnus guiding Rodimus in some aspects, or a partnership where they both bring different strengths to the table.
One plot idea could be that Rodimus and Ultra Magnus have to team up to face a new, powerful enemy that neither could defeat alone. Their different leadership styles - Rodimus' more impulsive and Ultra Magnus' by - the - book - could cause some initial friction but they learn to work together effectively.
The fanfiction might be set in a post - war scenario. Ultra Magnus and Rodimus could be working towards rebuilding their world. There could be political intrigue as they try to re - establish order, with different factions having different ideas on how to move forward. And their friendship or partnership could be a key factor in uniting the Transformers during this difficult time.
One common theme is loyalty. Both Optimus Prime and Ultra Magnus are known for their loyalty to the Autobot cause. In fanfiction, this can be explored further, like in a situation where their loyalty is tested. Another theme could be leadership. How they lead the Autobots together or in different scenarios. For example, they might face a difficult decision on whether to sacrifice a small group for the greater good of all Autobots. And there's also the theme of friendship. Their relationship as comrades can be deepened in fanfiction, showing how they support each other through tough times.
You can try looking on fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. These platforms usually have a large collection of Transformers fanfictions, including those featuring TFA Ultra Magnus and Optimus Prime.
Writers develop their relationship through shared challenges. For example, when they are on a mission to rescue captured Autobots. This forces them to rely on each other and builds trust. Another way is through dialogue. Meaningful conversations about their beliefs, goals, and fears can deepen their connection. Writers might also use flashbacks to show how their relationship has evolved over time, like an incident in their past that first brought them together.
Well, in Magnus x Alec lemon fanfiction, a frequent theme is the discovery of each other's desires. Since they come from different backgrounds, Magnus being a warlock and Alec a Shadowhunter, there's a lot of room for exploring how they understand and fulfill each other's needs. Additionally, themes of acceptance, both within themselves and from their respective communities, are quite common. The 'lemon' aspect can sometimes be used to show the deepening of their bond and the breaking of barriers between them.
Some fanfictions also explore the idea of self - discovery. Optimus Prime is still growing and learning about his role. Ultra Magnus, with his experience, can play a role in this journey. It could be about Optimus Prime realizing his true potential with Ultra Magnus' guidance, or both of them learning new things about themselves through their interactions.
