One characteristic is mutual trust. In allies novel, like in 'The Chronicles of Narnia', the main characters who are allies trust each other completely. They believe in each other's abilities and intentions, which helps them face the challenges in Narnia together.
I'm not sure specifically what 'allies in wonderland' is about. It could be a fictional story, a game, or something else. Without more context, it's hard to give a detailed account.
Well, in Merlin fanfiction, enemies and allies are really interesting. Sometimes, an ally can turn into an enemy because of a misunderstanding or a change in their goals. For example, Mordred was initially seen as a potential ally, but as the story progresses in some fanfictions, he becomes an enemy. And the way enemies are portrayed can also vary. Some are just pure evil, while others have reasons for their actions that make you almost sympathize with them. Allies, like Gwen, often bring stability and support to Merlin and Arthur's quests.
One example of an enemy in Merlin fanfiction could be Morgause. She's a powerful sorceress with her own plans for Camelot that often put her at odds with Merlin and Arthur. An ally would be Lancelot. He's always loyal to Arthur and is a skilled knight who helps in battles. Another enemy could be the Saxons, representing a threat from outside Camelot. And an ally like Gaius, who uses his knowledge of magic and medicine to support Merlin in his secret life as a sorcerer.
One possibility in Tinkerbell - Vidia fanfiction is that they form an unlikely alliance. Vidia, known for her independence, might find herself in a situation where she needs Tinkerbell's help. For instance, if she gets trapped in a part of the forest she's not familiar with and Tinkerbell uses her tinkering skills to free her. This could be the start of a new friendship.
They could be unlikely allies in a fanfiction. Agent 8, being new to the scene, might initially be distrusted by Agent 3. But as they face a common enemy, they start to work together. For instance, a powerful foe emerges that neither can defeat alone.
Gwen is one of his main allies. She has her own magical powers and often helps Ben in his adventures. They have a love - hate relationship at times but always come through for each other.
In this fanfic, Agumon might be a loner Digimon who is used to fighting on his own. Biyomon, on the other hand, is more community - oriented. When they first meet, they don't get along. But as the threat grows, they start to see the value in each other. Agumon learns about the importance of teamwork from Biyomon, and Biyomon learns to be more assertive from Agumon. Their partnership evolves over time as they face different challenges together.
