- Awesome Ego: A few of the contestants, such as the Bee, the Peacock, and the Rabbit, are all very confident and can be a little boastful, but it's in a lighthearted way, and the judges and the audience agree that they're absolutely delightful. (And given just who some of the contestants have been revealed to be, they've certainly earned the right to it.)
- Awesome Moments:
- Ken Jeong somehow missing that the Poodle was someone he knew personally immediately became a Never Live It Down moment for him. Just one week later, he redeems himself by making the one spot-on guess that week.
- Episode 6. The Monster has possibly the most cumbersome outfit of all, basically a dressed-up Bankruptcy Barrel with the "mask" being more of a lid - and yet in episode 6 he can bust dance moves in it, earning uproarious cheer. Especially impressive when it was revealed that the person inside the costume is not especially slender.
- The finale. The Monster — revealed to be T-Pain — defeated Donny Osmond and Gladys freaking Knight. A relatively young artist who's known for using a lot of Auto-Tune not only revealed that he has a truly stunning voice — he managed to beat two Living Legends.
- Awesome Music:
- "The Greatest Show", not only the perfect song choice for the Peacock, but as the very first performance it set the tone for the whole series.
- "What's Love Got to Do With It". The only time the Bee has gone with a song matching her own style (as a favor to someone she claims to be a "close friend" to boot), which brought down the house.
- At the meta level, a second American surprise guest appeared on the South Korean King of Masked Singer and wowed them with his rendition of the classic "Creep" by Radiohead. Let's just say Ken Jeong just earned that crown.
- Critical Dissonance: Downplayed. While critics were generally not fond of the series, audiences were somewhat more receptive (but still erring towards critical); at any rate, its ratings have been described as "the highest rated unscripted debut on any network in seven years, excluding post-NFL".
- Ensemble Dark Horse: While Peacock and Lion were already being touted as the strongest contenders, the Rabbit slowly gained attention for not only shifting song genres every time, but pulling them off and generally knowing how to work the crowd.
- Epileptic Trees: Par for the course for a series whose primary mystery is dragged out for several weeks. A popular one involves Donny Osmond being hospitalised for a shoulder injury being a cover story to keep him under the radar for an extended period of time - because he's the Peacock. They were right.
- Funny Moments: Episode 7. The addition of guest panelist JB Smoove led to several of these:
- First off, his habit of standing up every time he had to say something - probably just being polite, but after a while Ken found it annoying.Smoove: (while Ken is shoving him back down) I have solved a lot of mysteries like this. Who shot Ray-Ray....
(Lion drops to her haunches laughing)
Smoove: Nobody's grandma does this all day. (mimics her shimmy) [...] And just for my own purposes, I'ma let my wife know if they make that costume in her size - Is there a stinger on the back of that bad boy?
- Describing the Lion and Nick Cannon, who's in a shiny suit with a texture like a Christmas cracker, as "the snazziest prom couple I have ever seen".
- His words to the Bee:
Nick: Miley's daddy can't move like that no more. He gon' achy-break something.
- One guess as to the Rabbit's identity: Billy Ray Cyrus.
Smoove: (laughing) That was a good one, Nick...
Ken: No it wasn't a good one! (at Nick) C'mon, Not-Steve Harvey! C'mon! (massive audience reaction)
- First off, his habit of standing up every time he had to say something - probably just being polite, but after a while Ken found it annoying.
- He Really Can Sing: T-Pain already had a respectable career, but he's always been notorious for his use of auto-tune (albeit as a deliberate choice, not to cover mistakes). His songs as the Monster absolutely blew everyone away. His rendition of "Stay With Me" is considered to be one of the best performances on the show.
- Heartwarming Moments:
- Ken Jeong's Squee! upon the reveal that The Poodle is actually his one-time co-star Margaret Cho. His praise of her as a pioneer in Asian-American comedy and a personal inspiration to him is so sincere that it tugs the heartstrings.
- After going with mostly semi-recent pop tunes, the Bee reverts to her old-school soul diva style with two song choices dedicated to two other music legends, Tina Turner and the late Aretha Franklin. The second one is easily the showstopper of episode 8.
- Everyone squees over the Bee after she's finally unmasked as Gladys Knight. Kenan Thompson, who made a spot-on guess despite being Late to the Party, takes a moment to thank her for her contribution to African-American culture and much of his growing years.
- Hilarious in Hindsight:
- Tori Spelling being a unicorn, after having been involved in promotions for a wedding-themed My Little Pony: Friendship Is Magic season finale.
- Thanks to the semifinal episode, we got to watch Joey Fatone challenge a singing Bee.
- One review of the show off the bat compared it to, basically, "what if the new Philadelphia Flyers mascot sang 'Stay With Me', and was revealed to be Joey Fatone?'" It didn't happen all at once, but yes, Joey Fatone was there, and "Stay With Me" was performed — but not by Fatone.
- Nick Cannon made a slightly mean joke about Billy Ray Cyrus being a has-been - a few months later, Billy would have his revenge by being part of the critically and memetically popular "Old Town Road" (a country/hiphop track that blew up bigger than Nick's pure hiphop pieces).
- Just Here for Godzilla: Many people watch solely for the mystery of who the contestants are.
- Narm Charm: The costumes are totally ridiculous, but that's part of the whole appeal of the show; it and the mystery of who the singers are certainly gives it an edge over other singing competition shows.
- The Scrappy: The judges are often singled out for criticism, as they don't have particularly good chemistry together and tend to go for the absurd and funny, instead of making serious guesses about the singers' identities (e.g. they suggested Poodle was Ruth Bader Ginsburg and Kellyanne Conway before she was revealed to be Margaret Cho). This improved a little as the season went on, as they started to get more serious about their guesses — even the ones that were wrong were at least understandable. The exceptions to this are the guest judges(who are obviously Late to the Party), and Ken Jeong, whose career as a comedian makes some of his more bizarre moments make a bit more sense.
- Signature Scene: Peacock's rendition of "The Greatest Show" and Monster's performance of "Stay With Me" are the stand-out songs in the first season.
- Tear Jerker: Monster's soulful performance of "Stay With Me" in episode 8. It was enough to even bring judge Nicole Scherzinger to tears.
