These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Danger Days: The True Lives of the Fabulous Killjoys
Ho Yay: Many fans interpret the relationship between Dr. Death Defying and Show Pony this way. Also, in the song "Save Yourself, I'll Hold Them Back", the lyrics, "I'm the only friend that makes you cry/ you're a heart attack in black hair dye/ so just save yourself and I'll hold them back tonight," are sung. Considering Jet Star and the Kobra Kid are already dead at this point, and considering that the lyrics are being sung by Gerard Way, whose alter-ego is Party Poison, and considering Frank Iero's character Fun Ghoul has dyed-black hair, this is interpreted as ho-yay between Party Poison and Fun Ghoul by some fans.
Narm Charm: The "Na Na Na" video and "Art is the Weapon" trailer.
"Stop Having Fun" Guys: The sentiment of a lot of fans (especially on LJ) in response to the "shenanigans" the band did before the album's release, directed towards both the band and the fans who want to actually participate in the shenanigans.
Tear Jerker: "SING", "The Only Hope for Me is You", "The Kids From Yesterday", and "Summertime".
Specifically whenever they mention loved ones that they had to leave behind.
True Art Is Angsty: Not so much anymore. "Na Na Na" anyone? True art is apparently a (ridiculously fun) weapon.
Possibly played straight in the video for "SING".
Subverted with "Vampire Money." Based on interviews given about the song, it could be a rejection of all the angst that's crept into pop culture via Twilight.
Viewer Gender Confusion: Vaya and Vamos, from the Ultra V's. Are they boys? Skinny girls? It doesn't help that they're also very effeminate.
Unfortunate Implications: Volume, a member of the Ultra V's gets ghosted in the first issue. There's also a serious lack of POC characters in the comics, with the most commonly represented group being Asian, with more POC representation in Battery City than in the Zones. Considering the Dangerverse as a whole takes place in (what used to be) Southern California, it seems especially glaring that there's a lack of black and Hispanic representation.
