For the 2019 series, see here.
- Adorkable: A lot of the main characters fall into this:
- Wonder Woman herself showed some shades of this early on, particularly in trying to fit in with the other students and not doing a good job. Even after she became a more confident hero, she can still fall into this when trying a bit too hard to act cool or not completely getting something. She's just precious.
- Supergirl embraces this quite a bit. She may be clumsy and awkward, but she's cute and endearing when doing so.
- Ivy's shyness, reserved behavior, and awkward attempts to be cool are rather endearing.
- Batgirl embraces this. While she shows shades of this in the main series, she really embraces this trope in the Lego series, where she's much more into academics and structure than normal, and yet is still endearing.
- Ms. Martian is this in an interesting way. She's reserved and scared quite often, but you'll just want to give her a hug because of how sweet she is.
- Starfire, like most other versions of the character, embraces this trope. She's naive and somewhat simple minded, yet still pretty cute and endearing.
- Frost shows this quite a bit when she lets out her nerd side, and is prone to plenty of cute moments.
- Surprisingly enough, Big Barda can act this way, mostly when dealing with something unexpected that she knows little about, and reacts quite jovially.
- Jessica Cruz shows a bit of this. She's deeply insecure of her abilities as a Green Lantern, but it's part of her appeal because of how cute and persistent she is.
- Mera's Fish out of Water tendencies make her this. She's socially awkward and makes cheesy puns, but you can't help but love her for her persistence and sweetness.
- Raven is more downplayed example, but when Harley gets her to loosen up, she isn't afraid to show a more vulnerable, innocent side, making her come across as cute in her own way.
- Lena Luthor shows this in the Lego projects. Due to her ineffectual sympathetic villain qualities, she's actually quite endearing when trying to be taken seriously.
- Alternate Character Interpretation: It's briefly mentioned in "Clubbing" that Poison Ivy has done community service. Is she doing it voluntarily, for school, or did she do something illegal and was made to do community service afterwards? If the latter, then was Ivy once a villain who underwent a Heel–Face Turn?
- Continuity Lock-Out:
- The main series eventually evolved into this. Later episodes build upon earlier ones quite frequently. This also holds true for the movies. For example, you would have had to see at least "Super Hero High", "Tales Of The Kryptomites", and "Spring Break Prison" in order to understand the Intergalactic Games movie.
- This also holds true for the Lego projects, where you have had to see the Lego shorts and 22 minute special before going into the Lego Brain Drain movie.
- Ensemble Dark Horse: For what is essentially a background character, Hal has a following due to his handsome design.
- Fanon:
- The main girls are on a First-Name Basis with each other and call each other by their real names when not doing superhero work or schooling (minus Harley's name, whose name is really little more than a nickname for her real name "Harleen").
- The series makes it obvious that supervillains like Cheetah, Harley Quinn, and Poison Ivy are superheroes (in training) in this universe. Despite this, several fans either give them Dark and Troubled Pasts or have them be former criminals who underwent Heel-Face Turns prior to the series.
- Fan-Preferred Couple: When it comes to ships, HQ/WW, Batgirl/Supergirl, HQ/Ivy, Big Barda/Lady Shiva, and Flash/Frost are the most popular.
- Fashion-Victim Villain: Killer Moth's costume is a bizarre, garish mix of colors, including purple, chartreuse, and orange.
- Girl-Show Ghetto: The intention is to avoid this. Given the positive reception, it's successful at averting this.
- Growing the Beard:
- Season 1 is often criticized for having the shorts be too short, Katana, Supergirl and Batgirl being underutilized, and Alpha Bitch Cheetah being a Karma Houdini. Saving The Day has Cheetah be punished for her actions, and she's more downplayed in later episodes. The length of the shorts in season 2 is more consistent, with all of them (except the Hero Of The Month ones) regularly being 2.5-3.5 minutes long. While Katana is still underutilized, Supergirl and Batgirl get more screen time, especially in Super Hero High. Seasons 2 and 3 take things further.
- Season 4 is composed almost entirely of multi-part episodesnote , allowing the stories to get bolder and more interesting.
- He Really Can Act:
- In this case, it's "She really can act". Cristina Pucelli's performances as Catwoman and Amethyst are really well received. She captures the sultry allure and moral ambiguity of the former, and gives a great sense of formality to the latter.
- Really, most of the cast qualifies. It helps that all of them can voice both adult and teenage characters, especially with Grey DeLisle, Tara Strong, and Josh Keaton, among others, who voice the teenage versions of their regular adult characters.
- Hilarious in Hindsight:
- On My Little Pony: Friendship Is Magic, Tara Strong originally auditioned for Pinkie Pie. Now this show comes along, and she reprises the role of Harley Quinn, whose Adaptational Heroism makes her an expy of Pinkie Pie.
- Lauren Faust has wanted to make a show like this called Super Best Friends Forever into a full series but was shot down because CN claimed they already has a show like that (presumably meaning Steven Universe whose three female leads were quite similar in personality to Faust's version of Supergirl, Batgirl and Wondergirl). Cut to 2018 and they ended up picking up this show for their schedule and look who helped develop it?
- The whole concept (in both this and then the 2019 series) of adapting and compressing nearly the entire cast of characters of a famous comic-book franchise into all being the students in one school, would soon be taken into live-action film.
- In July 2014, a freelance developer named Jon Lazar took minidoll figures from the
LEGO Friends line and modified them into superheroines from both Marvel Comics and DC Comics. A few years later in 2016, LEGO and DC put out a line based on these toys, also featuring minidolls.
- It's Short, So It Sucks!: While it hasn't completely gone away and its standard with any YouTube series, there was more criticism early on with how short the episodes are (1.5-2.5 minutes long). Eventually, the shorts became longer, usually averaging in at about 3-4 minutes, which has lessened complaints.
- Jerkass Woobie:
- Blackfire may be cold with her sister, and others as well, but you can't help but feel bad for her when you consider she was pushed to focusing only on doing the best by Sinestro, and distancing herself from others, again because of Sinestro. Her looking fondly at the portrait with her and Starfire cements this.
- Lena Luthor is also this just for being such an Ineffectual Sympathetic Villain after her failures.
- Just Here for Godzilla: A significant amount of fans were drawn to the show because of Lauren Faust's involvement in the 2018 series.
- Launcher of a Thousand Ships: Unsurprisingly, Harley Quinn gets shipped off with a lot of characters. The main two are Wonder Woman and Poison Ivy.
- Moe:
- Pretty much all the main characters, and some background characters, as well, but special mention goes to Ivy and Supergirl.
- Mera is definitely this, both as a child and a teenager.
- Raven is also this, surprisingly enough, mostly with how her rougher edges are smoothed out, and she's more introverted.
- Narm Charm: All of the Lego projects are this, with their cheesy dialogue being really funny to watch.
- Older Than They Think:
- This is not the first show to age down Poison Ivy to that of a teen/preteen. That already happened on The Batman .
- Solomon Grundy fights Hal Jordan in "Ring Me Maybe Part 1", alluding to how he started out during The Golden Age of Comic Books as the enemy of Golden Age Green Lantern Alan Scott, Hal Jordan's predecessor, unlike how the cartoons make him an enemy of Batman.
- Poison Ivy being a Shrinking Violet fits many comics interpretations of her pre-villainous personality.
- Seasonal Rot: Season 5 took a sharp drop in quality, probably because the writing was on the wall that the series was going to be replaced with a new generation. The original animation studio and the original showrunner had their contracts run out and were replaced, and while Patrick Rieger's writing usually measured up to Shea Fontana's (and he was kept on for a few episodes of the 2019 show), Renegade Animation's output was wooden and cheap in comparison to what came before it, with a lot of static shots and obvious shortcuts. The ending looked good on paper, but fell flat compared to previous seasons, and the comics had to add an epilogue to introduce the new series and give fans of the old series one last visit with the characters.
- Tainted by the Preview: The initial artwork and bios for the toyline were met with heavy criticism and skepticism. The web-toon itself had a better reception though, especially because the designs look better animated.
- That One Boss: Harley in the matching game on the website. Any lead over her can and will be negated by her shuffle ability, so even if you did well against everybody else, she'll probably wipe the floor with you repeatedly.
- They Wasted a Perfectly Good Character:
- It's a wonder why The Flash and Wonder Woman are used here when their younger counterparts Kid Flash and Wonder Girl could fill the same roles with little to no problem.
- Conversely, some people see it as a waste that Batman and Superman have already graduated, and feel it would've been interesting to see the two as kid heroes, especially since many of their usual teammates, friends, and even love interests are still either students or far younger than them.
- Unintentionally Sympathetic: Solomon Grundy is meant to be a scary zombie person, but is such a buffoon you'll probably just feel bad for him.
- Win Back the Crowd: After Teen Titans Go! proved to be polarizing to the periphery demographic, this show and the Lego Justice League DVD movies proved that having lighthearted DC fare can still attract both kids and adults.
