Cathleen Bate, better known as Star and Stripe, is USA's No. 1 hero who wields the quirk called New Order. It is a quirk that allows her to create specific rules about virtually everything around her. With New Order, she can even manipulate the atmosphere.

Star and Stripe makes her debut appearance in chapter 328 of the manga. She is a big fan of Japan's former No. 1 hero, All Might, so it doesn't take a long time for her to decide to rush to Japan to lend them her power.

Unfortunately, before she even touches Japanese soil, she comes face to face with Shigaraki/All-For-One (AFO). Other than All Might, Star and Stripe is the only hero who manages to deal colossal damage to AFO. She may only appear in five chapters, but without her help, Midoriya and the other heroes wouldn’t have had time to create the right plan to take down AFO. We wish we could’ve seen more of her!

Mei Hatsume is a student from the Department of Support at U.A. High School. Her quirk is called Zoom, and as the name suggests, she can zoom in on any object up to five kilometers away. She actually created the original costumes for several students of class 1-A.

Hatsume loves inventing new devices to the point that she will gladly give them away to any heroes - not only as a way to support their activities, but also as a means of experimenting with new features while promoting her inventions at the same time.

Hatsume first appears in the story as early as chapter 25 of the manga. After that, she occasionally pops up for a short while. However, thanks to her unique and energetic nature, she always steals the spotlight whenever she makes an appearance.

Nana Shimura is the seventh user of the One-For-All quirk and lost her life battling All-For-One. She passed away long before the main story of My Hero Academia even began. However, none of the events in the story would've happened without her.

For starters, Nana Shimura was the master of a young man by the name of Toshinori Yagi, also known as All Might. As a matter of fact, All Might inherited his One-For-All quirk from Nana Shimura. Without Nana, there wouldn't be All Might.

On the other hand, Nana was also the estranged grandmother of a boy named Tenko Shimura, better known as Tomura Shigaraki. As a hero, Nana couldn't be there for her family, which caused her son to harbor a deep resentment towards heroes. That resentment translated into him harassing his son, Tenko, which is one of the main reasons why Shigaraki turned out to be the way he is today.

Rumi Usagiyama, more commonly known as Rabbit Hero: Mirko, is currently ranked fifth among pro heroes in Japan. Her Rabbit quirk allows her to have enhanced leg power and hearing ability. She can easily destroy solid ground with just a light stomp. Her leg strength also allows her to jump extremely high and move faster than most heroes.

That being said, what makes Mirko stand out from the rest is not her quirk, but rather her attitude. She is one of the most fearless heroes out there, diving head first into danger with a big smile on her face. The harder the fight, the more she enjoys herself. Even when the odds are stacked against her, her eyes will keep on burning as bright as the sun.

Most of the characters in this list are heroes, but the one who steals the spotlight from all of them is actually a villain by the name of Lady Nagant. Her real name is Kaina Tsutsumi and her quirk Rifle allows her to transform part of her arm into a long-range rifle. She is considered by many heroes to be the best long-range fighter in Japan. Even the pro hero Snipe admits that her skills are greater than his.

Lady Nagant is one of the escaped convicts from Tartarus. However, before she became a villain, she was actually a former pro hero who worked for the Public Safety Commission. She had done all kinds of shady work for the Commission, to the point that she no longer believes in the concept of heroes.

She made a couple of cameos here and there earlier on, but her major appearance happens in chapter 312 as she fights against Deku. Despite appearing only in five chapters, her tragic backstory, stoic nature, and amazing fighting ability are the reasons why she became one of the fans’ favorite characters.
