"The Struggle" Trophy
The Struggle Trophy is an important object in both Twilight Town and its digital counterpart. It signifies a person as the best fighter in the town, a sign of honor.
During the real Struggle competitions, it is handed over from the previous victor to this years winner (unless they are the same person). In the virtual Twilight Town, Roxas obtains this trophy after defeating Hayner and Vivi. In the real Twilight Town, Seifer held the trophy until he saw how much better Sora was at fending off the Nobodies. At that point, he gave the trophy to Sora as a symbol of respect for the warrior. The trophy was left behind in Twilight Town when Sora and Co. left for The World That Never Was.
The trophy itself is an abstract black statuette that houses four unique crystals. Each one is of a different color, and, according to Olette, there is only one of each. The digital version of the blue crystal was passed along to Sora by King Mickey, and thus, there were two blue crystals in the world, rather than just one.
