(Note: In the Japanese he's called Tuxedo Kamen or Tuxedo Kamen-sama which translates as "Tuxedo Mask") Mamoru is very originized and intelgent, almost the exact oppisite of Usagi, but he loves her anyway. He hopes to be a doctor or scietist for his profession. He has the power to heal things with his touch (though they don't talk about it much in the English anime.)

He's very protective of his daughter from the future, Chibi-Usa, which at times can make Usagi really jelous. Chibi-Usa and Usagi both love him dearly and they both call him "Mamo-chan."(In retutn he calls Usagi "Usa" or "Usako" which is translated as "Buns" in the English manga.NoteUsagi's name in the English manga is "Bunny.")

Now back to the past life stuff: In the Silver Melenium Mamoru was Prince of the Earth and his name was Prince Endymion. He fell in love with Princess Serenity, the Princess of the moon (it was a forbidden mach back then) and long story short, they died. But Queen Serenity sealed them in the Silver Cyrstal so they could be reborn on Earth and Hopefully find peace.

In the 30th century Mamoru is King Endymion, king of the Earth married to Neo Queen Serenity (Usagi in the future) and they have a daughter also named Usagi,(or Serenity in the English manga) but they call her Chibi-Usa.

My Big Rant like Speal:
Here's the main reason why the anime bugs me: Tuxedo Mask almost always saves Sailor Moon with a stupid rose. In the anime he's potrayed as nearly invincible with his magic rose, cape, and cane....it was cool at first but it gets OLD!

Anyway in the manga he's much cooler. he doesn't do that stupid rose flinging thig (Well OK he does it a little) He has his own attack ("Tuxedo smoking bomber" ...OK it's dorky, but hey it's there) He even gets his own crystal, the golden crystal.
