Derived from the abbreviation FM, meaning Full Metal, Fim is a capture the flag player in JKA/JK3. Seated among the top North American players, Fim is often associated with the term "emo" due to his tendency to attempt to lower people's expectations of him by convincing them he sucks. Nobody knows why Fim does this with certainty especially considering that it almost never works due to Fim being one of the fastest players of the game. When confronted with this fact, he almost always responds with the same statement declaring that while his speed is substantial, he lacks any form of aim and can only be considered a good offense player at best. This, however, is also untrue as Fim is one of the best Base Defense players, a position that can, at times, require significant ability aiming.
