It's difficult to enact change by yourself (even in the world of anime), but with the proper team at your back, anything is possible. The power of teamwork is an important element in most anime, and it's highlighted in popular series like Dragon Ball Z, Naruto, and My Hero Academia.
The strongest anime teams consist of superpowered individuals who have pledged themselves toward achieving a common goal. Sometimes, as with the Z Fighters of DBZ, this goal involves something altruistic like protecting humanity. But there are other anime teams, like the Akatsuki from Naruto, that have far more villainous intentions. Other anime teams don't have to pick sides, like Hakogaku from Yowamushi Pedal - they're just trying to support each other in athletic competition.
Whether their goal is heroic, villainous, or somewhere in between, these teams are a sum greater than their parts.
If you ask the average anime fan who the strongest fighter is, chances are they're going to say Goku - and those who don't will probably pick Vegeta instead. The Z Fighters - the team to which these Saiyan warriors belong - is full of powerful fighters. But it's not just huge muscles and beams of concentrated energy that make the Z Fighters great - they also have members who focus on intellectual pursuits, like Bulma.
Together, the members of the Z Fighters are powerful enough to take on dangerous enemies like Frieza, Cell, and more.
Naruto features several teams that boast incredible power, but the most formidable might be the Akatsuki. The Akatsuki's goal is to collect all nine Tailed Beasts - powerful creatures sealed inside peoples' bodies - and harness them as weapons to help them invade ninja villages.
The group consists of some of the most powerful and ruthless ninja in the world of Naruto - chief among them being Itachi, who massacred his entire clan with no assistance when he was only 13 years old; Hidan, a functional immortal; and Kisame, a powerful shark ninja whose weapon absorbs the energy of others and gives it to him.
Aside from the obvious atrocities committed by the Akatsuki, the group is also embroiled in a conspiracy that could easily lead to the destruction of the entire world.
The Straw Hats are a powerful group of pirates who sail the high seas in search of treasure. Each member brings something different to the table: Luffy is outlandishly strong and possesses the ability to stretch his body like gum; Usopp isn't as physically intimidating, but he has common sense on his side; and Chopper can turn into a muscle-bound reindeer.
There are plenty of other powerful and compelling characters among the group, and each is cunning with an unflagging loyalty to their fellow members, making them one of the strongest teams around.
Team Urameshi includes the five warriors who participate in Yu Yu Hakusho's Dark Tournament: Yusuke Urameshi, Kurama, Hiei, Kazuma Kuwabara, Genkai, and Koenma. Urameshi and Kuwabara are spirit detectives who spent a lot of time getting into fights in high school, Hiei and Kurama are demons with terrifying powers, Genkai is an experienced martial artist who taught many of the other characters everything they know, and Koenma is an actual god.
They're strong enough to eventually win the tournament, which is no easy feat by any means.
