They are a popular pairing because they are both very unique characters. Robin is a tactician with great intelligence, and Tiki is a powerful dragon. Their different natures create an interesting dynamic.
One good one might be 'The Bond of Robin and Tiki' which explores their relationship in a very sweet way. It delves into how they support each other during battles and in the growth of their respective characters.
I'm not sure if there is a specific fanfic exactly about that. There are tons of Fire Emblem fanfics out there, but this particular combination might be a bit rare. You could try searching on fanfic - specific websites like Archive of Our Own or FanFiction.net to see if it exists.
Love and friendship are also common themes. Some fanfics focus on the romantic aspect of their relationship, showing how they fall in love despite the odds. Others emphasize their friendship, how they support each other, whether it's in battles or in dealing with the politics and intrigues of the world around them. Robin can offer Tiki a different view of the world, and Tiki can provide Robin with her strength and wisdom.
In many Fire Emblem Grima x Tiki fanfictions, the theme of trust is key. Since Grima is a character that is often not trusted, the development of trust between him and Tiki can be a major plot point. Another common theme is the idea of prophecy. Given the rich lore of Fire Emblem, prophecies related to both Grima and Tiki can be explored in fanfiction, such as how they might fulfill or defy certain prophecies through their relationship.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). There are often tags related to 'Fire Emblem', 'Grima', and 'Tiki' which can help you narrow down the search. Another option is FanFiction.net, although the tagging system might be a bit less precise. You could also check out some Fire Emblem - related forums where fans might share their favorite fanfictions about these two characters.
A common theme is the exploration of their different personalities. Robin is often depicted as intelligent and strategic, while Tiki has her own charm and naivete. Their interactions based on these traits are frequently explored.
The length of the Fire Emblem Awakening story really depends on your playstyle. If you rush through the main quests, it might be around 25 hours. But if you take your time, do all the side quests and explore thoroughly, it could be over 60 hours.
One popular 'Fire Emblem Awakening' fanfic could be those that focus on character relationships, like the relationship between Chrom and Robin. There are also fanfics that explore alternate timelines or what - if scenarios in the game's universe. For example, a fanfic might explore what would have happened if a certain character had made a different decision during a crucial battle.
One great Fire Emblem Awakening fanfiction is 'A Future Forged in Bonds'. It delves deep into the relationships between the characters, exploring how they grow and change in different scenarios that the author has crafted. It has a really engaging plot that keeps you hooked from start to finish.
