Due To The Popularity And Powerful Influence Of Each Other, It Is Not Easy To Destroy An Anime Genre. 

However, some anime were so bad or great that they killed the genre they were a part of. Some of these genres have continued in other forms, while others have seemingly disappeared overnight from their former popularity.

At best, a certain genre of anime has been destroyed. These genres are still around, but taking them as seriously as they used to is hard. At worst, the genre is extinct. These genres exist today as a series of historical issues (related to anime) or as obscure references that few, if any, can notice

The Eminence In Shadow

What genre did it destroy?	Edgy Isekai & Isekai Parody
How did it destroy the genre?	It poked fun at the extremes of the genre and was surprisingly great

At first glance, The Eminence In Shadow was another “subversive” anime that combined adolescence with other subgenres of the genre. While the anime has defined itself thus far, The Eminence In Shadow is also a parody of Iskai’s genre and its pretentious deconstructions. In short, this anime destroyed two different forms of the Iskai genre.

The Eminence in Shadow pushed Edgy Eskai’s arbitrariness to the breaking point. Thanks to clever writing, Sid Kageno, a hilariously dark anti-hero and surprisingly good animation, makes the most of everything edgy Iskai anime offers. It’s too early to say that the anime in question has destroyed the Iskai subgenres forever, but now it’s getting harder for them to live up to that level of expectations.

Tokyo Ghoul

What genre did it destroy?	Horror
How did it destroy the genre?	With a low level of showing other anime and its bad sequels

Tokyo Ghoul was in a precarious position even before it hit the airwaves. Therefore, the anime (and especially its sequel, Root A ) was such a bad adaptation in and of itself that it ruined the reputation of the manga and the horror genre. For better or for worse, Tokyo Ghoul was the pinnacle of its genre. (And probably still is.)

Like other horror anime, Tokyo Ghoul makes up for its boring, scary moments with excessive violence and disturbing visuals. Its high prestige helped cement the awareness that all horror anime are merely low-level blood and gore fests. Tokyo Ghoul will remain a popular genre representation as long as better and different horror anime becomes mainstream.

Noblesse

What genre did it destroy?	Manhwa
How did it destroy the genre?	Compressing a long story into thirteen episodes

In 2020, manhwa adaptations will be the next big trend in anime. An anime version of the wildly popular Noblesse became the leader of this movement. Unfortunately, the biggest manhwa anime failed to meet expectations around the same year. Noblesse’s failure killed the excitement of the manhwa genre before it started.

Noblesse tried and failed to compress his lengthy source material into thirteen episodes. The soulless animation of the anime also left many points for discussion. Noblesse destroyed the manhwa genre and made the original Crunchyroll anime disappear. Manhwa anime may have a chance to catch on in the future, but Noblesse has killed that stream for now.

Mobile Suit Victory Gundam

What genre did it destroy?	Real Robot
How did it destroy the genre?	It became the biggest failure of his franchise.

Mobile Suit Gundam, ironically, created and then destroyed the real robot genre. This fall can be attributed to Victory Gundam. The genre was oversaturated then, and Victory was the first major failure of the Gundam series. Victory’s defeat led to a reboot of the Gundam series and the removal of its particular dark mood and Universal Century from the franchise.

Gundam is back on the scene with its incredibly nostalgic and franchise-saving reboot, Mobile Fighter G Gundam. Anime Mecca also followed this method and ensured the gradual death of its genre. It was replacing Neon Genesis Evangelion as the first mecha anime didn’t help Gundam either. The influence of the Real Robot genre is still tangible today, but it is no longer as powerful as it was in its early days.

The Melancholy of Haruhi Suzumiya

What genre did it destroy?	School Life
How did it destroy the genre?	Thanks to the Endless Eight arc

Thanks to the controversial Endless Eight arc, The Melancholy Of Haruhi Suzumiya anime lost all its excitement for itself and possibly the excitement for the school life genre. School life anime about a group of high schoolers with special characteristics (usually led by an eager girl) ruled the roost in the 2000s. Almost all these anime owe their existence to Haruhi.

But when Haruhi Suzumiya fell out of sight, it was followed by the death days of anime. Anime based on high school is still being made, but much has changed. The school life anime following the classic Haruhi Suzumiya parodied the genre or subverted its structures. The modern version of this genre depicts a form of high school romance.

Sword Art Online

What genre did it destroy?	Classic Isekai
How did it destroy the genre?	Telling vulgar stories and wasting the potential of its genre

Sword Art Online was not the first Iskai anime to tell its story in the world of video games, but it was the most influential. This anime created a trend in videogames Iskai anime, which had been saturated in the previous decade. Even though the genre is on the decline, the trend is still going strong. However, the gamified Iskai wasted a lot of potential from the Iskai genre.

The purpose of the Iskai genre is to cover different stories in different worlds. Sword Art Online’s popularity pushed the genre in a bad direction, limiting it to vulgar power fantasies told in the video game world. It’s almost impossible to find a modern Iskai anime that doesn’t feature repetitive fantasy clichés and clichés.

Neon Genesis Evangelion

What genre did it destroy?	Classic Mecha
How did it destroy the genre?	Very good deconstructions too

For many fans, Neon Genesis Evangelion was a complete rejection of the ridiculousness of the Super Robot subgenre. What fans prefer to forget is that this Evangelion brought destruction to the super robot subgenre that ruled itself at the time. Evangelion was so good at achieving its subversive goals that it destroyed two of the biggest forms of the mecha genre.

Before that, the Mecca anime was on its way out in 1995. Evangelion cemented this departure and ushered in a new kind of genre. For much of the 90s and 2000s, the mecha genre followed Evangelion’s dark, reflective, and violent (but understated) elements. In the end, if it weren’t for Tengen Toppa Gurren Lagann, the super robots wouldn’t be returning.

Puella Magi Madoka Magica

What genre did it destroy?	Modern Magical Girl
How did it destroy the genre?	Breaking the structure of the magical girl genre and its narrative in a new format

Puella Magi Madoka Magica is known for deconstructing the modern magical girl genre, featuring their adventures in cosmic horror stories with dark introspection. Ever since the success of Madoka, the supernatural girl genre has become subversive at best and overly dark at worst. This event marked the end of the Magical Girl genre.

Aside from the fact that this anime was made specifically for young girls, Magical Girl anime in an innocent and fantastical form like Sailor Moon is still rare today. Deconstructive Magical Girl anime became so popular that violence and meta-deconstructions are old examples of the genre. Dark Magical Girl animes have become a kind of jack-of-all-trades for anime fans even today.

Sailor Moon

What genre did it destroy?	Original Magical Girl
How did it destroy the genre?	Breaking stereotypes in the genre

Before Sailor Moon became the flagship of the modern magical girl genre, the genre used its magic factor quite literally. Before this, magical girls were only witches and celebrities. They took the stereotype of “girliness” and childish power fantasies to their highest limit. But when Sailor Moon hit the scene, it replaced the historical trends of fighting magical girls.

Sailor Moon gave birth to the magical girl genre. Not only were the magical girls now teenagers instead of children, but they were dealing with important issues and displaying dangerous struggles. Considered a bit overrated, Sailor Moon’s magical girls became a genre staple. Young witches and idols have returned, but mostly in genres like schoolgirl and anime idols.
