One common theme is redemption. Many fanfics deal with Hal trying to redeem himself from the things he's done or been through that have caused him hurt. For example, some might focus on his actions during the alien invasion and how he can make up for them.
The Ben Mason love story in Falling Skies is really about love in the face of extreme adversity. Ben is constantly in a fight for survival. His love story may involve a girl he meets during their battles against the aliens. They first notice each other when they are both on a dangerous mission. She might save his life, or vice versa. This event starts a connection between them. As they continue to fight side by side, they get to know each other better. They learn about each other's past, their dreams before the invasion. Their love grows as they see the best and worst in each other during this difficult time, and it becomes a source of strength for both of them in the midst of the chaos of the alien - occupied world.
One great Falling Skies Hal Hurt fanfiction is 'Hal's Struggles' on FanFiction.net. It really delves into Hal's emotional pain after his experiences in the show. The author does a wonderful job of portraying his inner turmoil.
The key elements of Ben Mason's love story in Falling Skies include survival. Since they are all fighting for their lives against the aliens, every relationship is colored by this. Also, the sense of community within the resistance. Ben forms relationships within this group, and his love story may start from a simple bond of comradeship. And finally, the hope for a better future. His love interest and he might be drawn to each other because they both have a vision for a world free from the alien threat, and this shared hope cements their relationship.
It could be Vilgax. He's one of Ben's most powerful enemies. Vilgax is always looking for ways to defeat Ben, and he might come up with a new and devious plan to hurt him. Maybe he teams up with other villains to ambush Ben when he's least expecting it.
One idea could be exploring the backstories of the secondary characters more in - depth. For example, we could learn about the life of a random resistance fighter before the alien invasion. Another idea is to create an alternate ending where the humans win in a completely different way than in the show. Maybe they develop a super - weapon earlier. Also, a fanfiction could focus on the relationships between different alien species and how they interact with each other outside of their interactions with humans.
As mentioned before, it could be rogue skitters. They are often portrayed as a threat in the show, and kidnapping Matt would be a strategic move for them.
There are also the possibility of some inter - dimensional beings. In the Ben 10 universe, there are many different dimensions. If a being from another dimension comes through with the intention of causing chaos, they could target Ben. They might have powers that are completely foreign to Ben and his allies, making it difficult for him to defend against them. And let's not forget about the possibility of some of Ben's old enemies teaming up. If they work together, they could come up with a plan to really hurt Ben, whether it's physically or by ruining his reputation among the people he protects.
