Although the movie theoretically promotes the concept of international cooperation to defeat threats, any true positive takeaway is neutralized by the movie's total divorce from reality and nonstop violent mayhem.
Positive Role Models & Representations
Constant extreme -- though generally bloodless -- action violence. A man has a white-hot metal mask affixed to his face. Characters are shot, decapitated, and stabbed and slashed with swords and throwing stars. Characters fight both hand-to-hand and with firearms, and there are intense martial arts sequences. People fall from great heights. Planes, ships, and other vehicles fire on each other with a plethora of weapons and missiles. Lots of general mayhem and destruction. In flashback, children engage in brutal violence involving frying pans, flames, martial arts weapons, and more. A child murders a teacher -- it's off-screen, but the body is seen. Surgical imagery.
Some kissing, cleavage, and discussion of "touching."
Some strong language, including "s--t," "bastards," "piss," "a--holes," "damn," "hell," "bitch," "crap," "goddamn," "oh my God," and more.
The film is based on a cartoon series that itself was based on a toy line (and the movie was actually co-produced by Hasbro, which makes those toys), so you could argue that the whole thing is an exercise in product placement. Other brands visible or mentioned include Hummer, Mercedes-Benz, Double Bubble, and Cisco.

A super-soldier serum lets people "feel no pain" and has implied adddictive and narcotic effects.
