AW Node???

I lost my champ on Node 1 in AW in which Nick Fury was the opponent. I made a mistake by not dodging his SP1, and for some reason his SP1 killed my champ despite my champ being 100% health. So in a sense he basically one shotted me with his SP1. How is it possible that you could lose that way?
For reference it was 5* awakened maxed Nick Fury, and my champ was a 6*R3 maxed out awakened Apoc.
