MOTRO (2016)

"The nefarious Reptoids, defeated and relinquished to hidden outskirts away from the Northern Kingdom, abscond with the human race's final hope for survival-the last of their children. Motro convinces the city's elders to sacrifice themselves to reveal the Reptoids' location so the children may still be rescued, but they're met with a horrifying discovery. Motro, with great warriors and a squadron of tri-tankerbeasts at his side, must decide what it means to save humanity when faced with extinction or a grisly new future."
