It's called "Guardians" in English. Found it on iTunes for $.99.
The best way to describe it would be: If the Avengers had been made in the late 80s/early 90s by a young Michael Bay.
The story is ridiculously dumb, and I hope it was a mistake in translation. Basically, a scientist tries to create super heroes, but fails. A new guy takes over and has more success, but overall the project is a failure. The disgraced original scientist turns into a super villain and to stop him they recruit that scientist's creations...heroes. WTF? Seriously, they're super powered people, how did he fail?
Anyway, there's:
-The guy who can turn into a bear. He has three modes: Human, Bear head, and all bear. Later they strap a Gatling gun to him.
-Invisible chick. (Played by the smoking hot, Alina Lanina. Seriously, the cinematographer made love to her in this movie. It's amazing.)

-Rock guy. No, he's not made of rocks, he controls them. It's basically telekinesis, but only with rocks. It's as dumb as it sounds. Later they give him a whip. It continues to be dumb.
-Ninja Flash. He's super fast and carries two monstrous blades that could only exist in a Japanese cartoon or RPG.
All of them are ridiculously ineffective. I honestly laughed at how terrible the filmmakers made them look.
The way they "win" is hilariously stupid.
If you're looking for unintentional chuckles and long shots of a gorgeous woman that'll put lead in your pencil, this is a great way to spend 99 cents.
OH! There's even a credits scene to setup a sequel!
