[1] MCZ is notable for being the first female group to hold a solo concert at National Olympic Stadium in Japan, as well as providing theme music for anime television series such as Sailor Moon, Dragon Ball, and Pokémon.

[8] In 2016, their first overseas tour titled Trans America Ultra Live was held in Hawaii, Los Angeles, and New York.

On stage, Momoiro Clover Z members are easily distinguished by the colors of their clothes, similar to the characters from Super Sentai[10] or Power Rangers.

In March 2009, they became a five-member unit composed of Reni Takagi, Kanako Momota, Akari Hayami, Shiori Tamai, and Ayaka Sasaki.

[17] In March 2010, the girls stated their goals: to take first place on Oricon, to participate in Kōhaku Uta Gassen, to perform at Budokan.

The group's first single with King was "Pinky Jones", composed by Narasaki from the Japanese rock band Coaltar of the Deepers with a "more chaotic" approach than previous songs.

[22] In January 2011 at the release event for a new song, sub-leader Akari Hayami stated that she had decided to withdraw from the group in April.

Momoiro Clover Z's first single after Hayami's departure was "Z Densetsu: Owarinaki Kakumei", accompanied by a new group image and stage performance.

[26] The girls wore outfits with helmets and so-called "transformation belts" reminiscent of Japanese superhero movies, and the music video also borrowed from such "Super Sentai" imagery.

Later in December, Hotexpress described the band as the number-one breakthrough idol artist of 2011 and stated that the album became a big turning point for them.

[27][28] On Christmas Day, 2011, Momoiro Clover Z gave a concert at Saitama Super Arena to their biggest audience to date: all 10,000 tickets were sold out.

In June, Momoiro Clover Z opened a national tour, which closed with a sold-out show at Seibu Dome in August to a capacity crowd of 37,000 fans.

[37] On December 31, Momoiro Clover Z performed at Kōhaku Uta Gassen, an annual New-Year-Eve music show hosted by NHK, for the first time.

It sold 180,000 copies in the first week and debuted on top of the Oricon charts, with the first album Battle and Romance resurging to number two.

[53] On January 28, 2015, Momoiro Clover Z released a collaboration single with the American hard rock band KISS, titled "Yume no Ukiyo ni Saitemina".

[54][55] An alternate mix of the single's title song was also included as an opening track on the Japanese-only SHM-CD album Best of KISS 40, released in Japan on the same day.

[56][57] In February 2015, a joint performance recorded by Momoiro Clover Z and Rats & Star for the Fuji TV show Music Fair was removed from broadcast due to controversy over the appearance of both groups in blackface in the performance, a photo of which Rats & Star had tweeted before the broadcast date after recording.

[59] Amid the controversy, Momoiro Clover Z cancelled their appearance at a Foreign Correspondents' Club of Japan film screening.

[60] Momoiro Clover Z provided the theme song, "Z no Chikai" which was released as their fifteenth single on April 29, 2015, for the Dragon Ball Z: Resurrection 'F' theatrical anime film.

[69] Some of Momoiro Clover's works are quite complex, switching from one musical style to another during one song and connecting "seemingly unconnected melodies".

[67][68] The group has worked with many noted songwriters and musicians, belonging to different genres of music, from pop to punk and heavy metal.

[67][68] Ian Martin from The Japan Times dubbed Momoiro Clover "a pop group who provoke squealing, teenage admiration from punks, indie kids, noise musicians and heavy-psychedelic longhairs throughout the Japanese underground music scene".
