- Awesome Music: "World War III", "Shelf" and their cover of "Poor Unfortunate Souls".
- Base Breaker: Nick Jonas and Joe Jonas' solo projects. Some love Joe's solo album Fastlife, while others hate it, the same for Nick Jonas And The Administration's Who I Am.
- And when Nick and Joe cover each other's songs, there will, inevitably, be fights that break out over whether or not the brother covering it is doing it better than the original.
- Lines, Vines And Trying Times qualifies. Fandom's pretty evenly split on whether to love it or hate it, since it's something of a departure from their previous straight-up pop rock sound.
- And a new one: With Joe and Nick using Precision F Strikes, the fandom's pretty divided as to whether it just doesn't bug them, or whether it sounds cheap and is just an attempt by the band to get people to see they've "grown up".
- Their new single "Pom Poms" has already turned into this. There seems to be three camps about it: 1. They hate the lyrics (and the [leaked] music video) and miss their old sound, circa "A Little Bit Longer". 2. They like both and see no problems with it. And 3. the group who think it's over-hyped and doesn't live up to it.
- "Pom Poms" is even a base breaker critically. There's some who think it's a great pop song that's fun, and then there's some who hate it and its lack of meaning.
- Critical Dissonance: A given, considering that critics usually see them as a Boyband first, 'legitimate musicians' second.
- Crowning Moment of Funny: "Oh, how the tables have turned." And Joe dancing to "Single Ladies".
- Crowning Moment of Heartwarming: "Hold On". Definitely.
When you love someone
And they break your heart
Don't give up on love
Have faith, restart
Just hold on
- Crowning Music of Awesome: "Heart and Soul" from Camp Rock 2. Say what you want about the group or the movie, you will love that song.
- Covered Up: Their "clean" version of "Year 3000" is better known than the original version in America (the All Music reviews of their albums seem to think they wrote it).
- Ear Worm: When You Look Me in the Eyes, Burnin' Up, SOS.
- Pretty much all of their songs, at some point or another.
- Ensemble Darkhorse: Big Rob, who really makes "Burnin Up" more enjoyable.
- Fanon Discontinuity: Lines, Vines And Trying Times, since it's a Base Breaker, and some fans prefer to pretend it (and the brothers' respective solo careers) never happened.
- Fridge Horror: Following the theory that "Black Keys" is about self-harm, what can the line "the lights out never had this bright a glow" mean other than the singer being tempted with the idea of suicide?
- Made even worse with "Wedding Bells", which all but outright states that the singer got drunk upon hearing the news, as well as the line "if I fall asleep, then wake me up cause I'm trying to see the light", which continues with the implications of suicidal thoughts. (And, like "Black Keys" and "A Little Bit Longer", Nick wrote "Wedding Bells" on his own.)
- Friendly Fandoms: Surprisingly friendly with the 30 Seconds to Mars fanbase. The Jonas Brothers reunion show at Radio City Music Hall was aired live on Mars' online music pay-per-view event service, VyRT. This made them the first band besides 30 Seconds to Mars themselves to stream a concert with the service. The Mars fanbase, the Echelon, took time on the VyRT site and other social networks to answer questions about the service, help overseas fans figure out what time the stream would be airing, and explain to the parents of Jonas fans that, yes, their credit card info WILL be safe if they pay for the ticket. Most Jonas Brothers fans appreciated the help. Of course, there was the occasional cross-Fan Dumb Flame War and some Echelon members were merely assisting Jonas Brothers fans because the financial and critical success of the Radio City show stream would benefit VyRT and Mars in the long run.
- He Really Can Act: Nick Jonas played Marius in Les MisÚrables rather well.
- Hilarious in Hindsight: "Video Girl" is about girls in music videos and how they aren't going to do it again. Following his break-up with Taylor Swift, Joe Jonas dated (and then split with) Camilla Belle, who was in the video for "Lovebug".
- Hype Backlash: From their own fandom over "Pom-poms", which has been so hyped by the group (and a good chunk of the fandom) that some people feel disappointed.
- Incest Yay Shipping: And how, with a surprisingly large portion of the fandom.
- Iron Woobie: People tend to perceive Nick as this, if not all three of the boys, and it's referenced in "Hollywood".
Now we're making headlines, primetime, saying 'what a story'...
- To be fair, it is somewhat justified, because before they were picked up by Disney, they worked for Columbia, who basically dicked around with them and kept pushing back the release of their album, which got very little advertisement aside from what the boys did personally, and very nearly went bankrupt before Disney signed them.
- And, of course, Nick has his diabetes.
- Launcher of a Thousand Ships: All three. Joe's been paired with his girlfriends, his brothers, any one of the other Disney stars, male or female. Nick's gotten the same treatment, and even Kevin's gotten in on it. (And one of the most popular pairings for Kevin is him and Zac Efron.)
- Some Anvils Need to Be Dropped: The opening rap for "Don't Charge Me For The Crime" manages to make a very good point about the American system.
The verdict came in and it said I was guilty
I looked at the judge, "Hey America built me."
Tried to get rich but they label me filthy
- Tear Jerker: Their new song "Wedding Bells", penned by Nick about Miley Cyrus' engagement.
I don't wanna love
If it's not you
No, I don't wanna hear the wedding bells prove
That we can't try, one last time
No, I don't wanna hear the wedding bells chime
- "A Little Bit Longer", which was written about Nick's diabetes.
- "Black Keys", which some have theorized is about self-harm.
- Yoko Oh No: When Miley Cyrus and later Selena Gomez dated Nick (And even later Delta Goodrem) and when Demi Lovato and Taylor Swift dated Joe. Oddly enough, there wasn't a whole lot of this trope in play when the oldest, Kevin, got married in 2009.
- It's Kevin, so it's really not that surprising.
