4. Katana

Here’s another comic book character who was ruined in the movies. In an extended and lame Suicide Squad cameo, Katana was assigned to be Rick Flag’s bodyguard. And then director David Ayer apparently forgot to introduce her.

In common with numerous other superheroes, Katana has a tragic origin story. Her entire family was killed, and in response she became a vigilante. In addition to being highly skilled at fighting with her trusty katana, as a Samurai she became proficient with a bow and arrow, shuriken, caltrop, and just about any other projectile weapon.

It can be said that her katana sword, The Soultaker, is a mystical weapon that imparts various attributes to its wielder, including enlightenment and immortality. But, as Green Arrow said, these gifts shouldn't be taken literally.

In any event, Katana is awesome, even without the Soultaker.
