As Tuxedo Mask he throws a red rose that seems to have a razor sharp tip. If needed he can throw more that one at a time.
He also uses his cane by extending it out. Sometimes it is used to block with.
As the Moon Light Knight (His spirit that protected the senshi when Mamoru lost his memory after fighting Queen Beryl) he threw white roses and used a saber instead of a cane.
He only transforms on camera once. (Dub) (To the great surprise of Usagi), he took out a red rose and after a very short change he was in his tuxedo.
Tuxedo Mask is the alter-ego of Chiba Mamoru (Darien). He fights along side the senshi protecting and helping them. As he is destined to be with Usagi he protects her as best he can. When he finds out that Chibi-Usa is their future daughter he is even more protective of her than he was before. The attention that he gives Chibi-Usa makes Usagi very jealous.
His future self- King Endymion- once gave him recurring nightmares that told him that if he and Usagi were together she would be put in great danger. As a result Mamoru broke up with her and tried to avoid her as best he could. Usagi didn't understand why until she too had the same dream. Once they got to the future the king told them that it had been to test the strength of their feelings, because they would be tested by the evil forces and their love must be strong.
