Ultra Magnus is often portrayed as a strict and disciplined Autobot. He adheres to the rules and expects others to do the same. However, in some fanfictions, he also has a softer side that he shows to the reader. He might be protective of the reader, using his strength and strategic mind to keep them out of harm's way.
One common way could be through using his magic in a subtle way. For example, he might use magic to create situations where Alec has no choice but to follow his lead. Maybe he makes it seem like the only option for Alec to protect his friends or family is to do what Magnus wants.
Ahriman is an important character. He is one of Magnus's lieutenants and plays a significant role in the legion's affairs. The Emperor also features prominently as Magnus's father and the overarching authority in the Imperium. There are also other Space Marines in Magnus's legion who are part of the story.
In the context of a fanfic, Magnus might use his magic in a positive way. He could create a magical bond or a truth - revealing spell between him and Alec (with Alec's consent, of course). This would allow Alec to see into Magnus' thoughts and feelings, and he would know for sure that Magnus is not cheating. Magnus could also start spending more time with Alec and less time on his own or with other people, at least until Alec's suspicions are completely gone.
One challenge could be understanding baby Raphael's needs. Since Magnus may not have had much experience with babies, he might struggle to figure out why Raphael is crying - whether it's because he's hungry, tired, or in need of a diaper change.
One characteristic is the blend of their different worlds. Magnus comes from his own universe and Percy from his, and in fanfiction, these two worlds often collide in interesting ways. Another is the exploration of their friendship or rivalry. Sometimes they start as rivals but end up as friends. Also, the use of their unique powers. Percy's water - related powers and Magnus' magic create exciting action scenes in the fanfictions.
Will in fanfic is often depicted as brave and a bit of a rebel. He's not afraid to take risks and is always ready to fight for what he believes in. Jem, on the other hand, is more calm and collected. He provides a sense of stability to the group. Magnus is flamboyant and powerful. His magic always adds an element of wonder to the story.
One characteristic is the focus on the relationship between Alec and Magnus. It could be their romantic relationship, like in many fanfics where their love story is explored in great detail. Another is the exploration of their individual personalities. For instance, Alec's loyalty and Magnus's magic are often highlighted.
In Transformers fanfiction, Ultra Magnus and Wheeljack can have various interactions. They might be comrades in a battle against the Decepticons. Ultra Magnus, with his strict sense of duty, could initially be at odds with the more maverick Wheeljack, but over time, they could learn to respect each other's skills and approaches.
In fanfiction, the Clary and Magnus kiss is often a very passionate and significant moment. It can represent a deepening of their relationship, whether it's a newfound connection or a strengthening of an existing bond. Writers might use this kiss to show the characters' growth, as Clary might be becoming more open to the magical world that Magnus represents, and Magnus might be letting his guard down more around Clary.
