Useless Ability Becomes Badass

Not all powers are awesome in every shounen manga series. Some are just really lame and useless that it makes you wonder how the protagonist survives so long in the series with such power. But that what makes them badasses, they utilize their seemingly useless power and defeat the enemies that get in their way!
