Mamoru Chiba (Sailor Moon and Sailor Moon R)

Mamoru Chiba is the reincarnation of Prince Endymion and is Usagi Tsukino's love interest. He is the civilian identity of Tuxedo Mask.

Why he's a true disgrace to the Sailor Senshi
Note: This only applies in Sailor Moon and Sailor Moon R, not Sailor Moon S, Sailor Moon SuperS, Sailor Moon Sailor Stars, and Sailor Moon Crystal.
 * 1) He sabotaged his relationship with Usagi just to be a jerk!
 * 2) *At one point in Sailor Moon R, Mamoru had a recurring dream where Usagi died because of their relationship, and he resolves to break up with her.
 * 3) Mamoru practically did nothing at all for the Sailor Senshi; especially Usagi after he left.
 * 4) Speaking of Usagi, he has been a huge jerk to her for a very long time! (Mostly in the First and Second Season)
 * 5) *He constantly knocks her down emotionally.
 * 6) **Examples: He kept telling her that she's not pretty and that she has no inner beauty and sabotaged his relationship with Usagi as mentioned in BQ #2.
 * 7) Mamoru exists ONLY to help Sailor Senshi.
 * 8) *In fact, his appearance makes the problems harder for the Sailor Senshi!
 * 9) He's terrible at providing moral support.
 * 10) *Example: The first time that Mamoru and Usagi meet as Tuxedo Mask and Sailor Moon, she is crying because she's having trouble defeating Morga. Tuxedo Mask tells her, "You must remember, crying isn't going to solve any of your problems". First off, have you ever had someone tell you to stop crying? It just makes you cry more. And that's exactly what happens. Sailor Moon just cries harder.
 * 11) Due to the fact he is terrible at fighting and keeps giving bad advice, he keeps getting his butt kicked, and to an extent, kidnapped!

Redeeming qualities

 * 1) He has some amusing moments in the entire series.
 * 2) He redeemed himself in Sailor Moon S, Sailor Moon SuperS, Sailor Moon Sailor Stars, and Sailor Moon Crystal.
 * 3) He has a kind of handsome character design.
 * 4) His attempts at helping the Sailor Senshi are well-meant despite not really helping that much.
 * 5) Robbie Daymond and Vincent Corazza do a great job playing him.

Trivia

 * 1) His name, just like the girls', carries a pun. His surname "Chiba" means local and contains the kanji 地 (chi) which also appears in the word "Chikyuu", the Japanese name for Earth and 場 (ba), meaning place or location.
 * 2) His given name "Mamoru" (衛) means to protect (Which he failed at doing).
