Common themes revolve around his insecurities. As a young werewolf, he has a lot of insecurities which are often explored in fanfiction. His place in the pack is another theme. Is he an outcast? Or is he a key member? How he proves himself within the pack is often written about. And the theme of facing danger together with the pack, like fighting against other supernatural threats, is also quite common.
Well, it could be that Liam is kidnapped by a rival pack who wants to use him to get information about his own pack. Maybe they think he's a weak link and can be easily manipulated.
One common theme is innocence. Since it's about baby Liam, his pure and innocent nature is often highlighted. Another theme is protection. Other characters in the fanfics usually feel very protective of the baby Liam.
It could be another werewolf from a different pack. There are often rivalries between packs in the Teen Wolf universe, and someone might see Liam as a way to gain an advantage over his pack.
Well, I really liked 'Liam Dunbar: The Lost Years'. It's a fanfiction that fills in the gaps of Liam's past, giving more depth to his character. 'Liam in the Parallel World' is also quite fascinating. It imagines Liam in a different world with different challenges. Then there's 'Liam and the Forbidden Friendship' which shows his relationship with an unlikely character in an interesting way.
One great 'baby liam dunbar fanfic' is 'Liam's New Beginnings'. It beautifully portrays Liam as a baby in a really heart - warming way. The author does an amazing job of showing his innocence and the potential of the character from a very young age.
In the 'Ghost of Bobby Dunbar' story, Bobby Dunbar was a boy whose vanishing set off a chain of events. He was the central figure around whom the mystery of the wrong identification revolved. After his disappearance, the family was desperate to find him, and when a boy was found, they believed he was Bobby, but it turned out to be a case of mistaken identity.
In Teen Wolf fanfiction, 'a wolf in sheep's clothing' could refer to a character who appears harmless but is actually dangerous. For example, a new student in Beacon Hills who seems friendly and ordinary at first, like a sheep, but later turns out to be a powerful and perhaps malevolent werewolf, a wolf in disguise.
There are many Teen Wolf fanfictions that focus on Stiles in a more appropriate way. You can look for ones on fanfiction.net or Archive of Our Own. Just search for 'Stiles' and filter through the results to find stories that match your taste without the inappropriate content.
One example could be a character who pretends to be a hunter ally but is actually a werewolf working for a more sinister force. They might use their guise as a hunter supporter to get close to the pack and gather information for their evil masters.
