• Adaptational Badass: After the first season of the anime, his importance quickly faded, as did his badassery ratio. Reputedly, the director of the anime hated his character. By contrast, he retains a larger role in the manga.
• Anti-Villain: After his first brainwashing session at Beryl's hands, he still retained many of his noble qualities and became one of these.
• Arranged Marriage: In the live-action, with a girl named Hina Kousaka (the daughter of his old caretaker). He still falls for Usagi, and Hina later lets him go willingly.
• The Artifact: In the anime, especially during S and Super S. He started as a Satellite Character to give Usagi someone to emote at, but he and Usagi hit the Relationship Ceiling at the end of R, and meanwhile Usagi had lots of friends and characters to emote at, so he basically didn't do much before he was Put on a Bus destined to crash.
• Badass Normal: In live action he doesn't seem to have any inherent powers.
• Betty and Veronica: The Archie for Usagi's Betty and Rei's Veronica. He chooses Usagi.
• Big Brother Mentor: To the other Inner Senshi, specially Ami. This is the basis for the Ami/Mamoru pairing.
• Brainwashed and Crazy: The worst offender in the anime.
  • In the manga too. While one of the arcs in which he receives this treatment, the mini-arc about Nehellenia's return, does not exist in the manga, Black Lady and Galaxia do not let poor Mamoru miss his regular dose of Brainwashed and Crazy.
• Bus Crash: In Stars. His plane never arrives in America.
• Butt Monkey: Guy has no luck when it comes to being a victim.
• Chick Magnet: And suffering for it, as many female villains (and two males) have a crush on him, which usually means they want to turn him into their obedient manslave.
• Coat, Hat, Mask
• The Comically Serious: Sometimes.
• Distressed Dude: More in the anime, though his manga self also wasn't free.
• Even the Guys Want Him: In the anime, Fiore was head over heels in love with him, and Fish Eye also found him really handsome.
• Evil Costume Switch: In PGSM when Mamoru is possessed by Metallia's energy.
• Gentleman Thief: In the beginning, more so in the manga, whereas he's more of a superhero in the anime.
• Hot Shoujo Dad: Will become this once Chibi-Usa is properly born.
• Ill Boy: In Super S, as The Dead Circus's influence spreads on Earth. He heals once the enemy is defeated, though.
• Ineffectual Loner: Sort of.
• It's Not You, It's Me: In R, he starts doing this to Usagi after having several nightmares about Usagi's upcoming death in their wedding day.
  • This is also done to a lesser degree in Super S, when he starts to become sick and fears that Usagi would catch his infection. Little did he know his illness wasn't related to any viruses, but to the presence of the Dead Moon Circus.
• Jerk with a Heart of Gold: In the beginning of the anime.
• Mask Power
• Montague Counterpart: In the first season, until he and Usagi recover their memories of their past lives.
• Mind Rape: The reason behind his nightmares. Actually, these were sent to him by... his future self. Meaning, Mamoru had been mindraping himself all the time.
• Mysterious Protector
• Non Indicative Name: The mask part is there, but he wears white tie and tails instead of a tuxedo.
• The One Guy
• Sensitive Guy and Manly Man: Manly Man to Motoki's Sensitive Guy.
• Shallow Love Interest: In the anime; from the second season onward, as he ended Overshadowed by Awesome.
• Sharp Dressed Man
• Simple Staff: His cane, which he could extend at will in the anime.
• Something about a Rose: His other ability in the anime.
• Tall, Dark and Handsome
• Team Dad: Acts like a brother to the Senshi (specially to Ami), keeps Usagi and Chibi-Usa with their feet on Earth, in the S season he talks to the Inner Senshi directly to try finding out about their reasons.
• Useless Boyfriend
• The Worf Effect

• Alien Animals: Cat aliens from the planet Mau.
• Cats Are Magic: Well, not all cats, just alien ones with crescent moon sigils.
• Cats Are Snarkers: Are they EVER!
• Cute Kitten
• Killed Off for Real: In the manga, with an odd What Happened to the Mouse? feel, as they're the only ones of Usagi's friends not shown to be rescurrected.
• Mentor Mascot
