I only ask this because

1. A fighters heritage etc interests me
2. I saw an interview where I think he said he was Spanish or something and
3. His nickname is "magrinho" which is skinny in Portuguese and you don't see many fighters who don't speak Portuguese having a Portuguese nickname

Please comment with evidence of what he is. You can do it in less than 75 words since its in the comments, something that it will not let me do as a FanPost right now.
