Roxas/Xion
Roxas's and Xion's weapons are keyblades. The names of the weapons are mostly associated with the pain of parting and loneliness, or light phenomena. Their joke weapons are umbrellas and the fighting styles are similar to Sora's in previous games. The zero gear allows them to use a more powerful version of the Kingdom Key, however Roxas can dual wield Oathkeeper and Oblivion when using the Zero Gear with three ability units. Either Roxas or Xion an wield Two Become One when equiping the zero gear with two ability units.

As a boss, he is shown to be more graceful than as being a playable character. His "joke weapons" are Round Fan and Absolute, Round Fan is nothing more than a large purple Japanese fan and Absolute is a large purple and black Nobody symbol with a heart symbol inside it.
