Whoa, we did not see this dark reveal coming in the new Japanese international trailer for Marvel's Big Hero 6. Spoilers ahead.

Turns out the little boy is an orphan? Or maybe that's his brother, or dad? I don't know. But it looks like whoever appeared in the video is the original inventor of Baymax (the big white, robot). And it was all I could do not to collapse into a puddle of joy/sadness when Baymax displayed the comparative pain chart across his chest! This movie is killing me! Can't wait.

Big Hero 6 will premiere in theaters on November 7th.
