When I think of Emilio/Luis, in my mind I see this youthful, vibrant guy, always friendly and willing to lend a helping hand, not too cool to get silly and goofy at times, and with a really pleasant, soothing singing voice. When I was a child, I actually thought it was Luis singing on all those live action Raposo segments, so I still kind of associate them with him, even though I know now that I was mistaken.
We older fans always kind of affectionately ribbed Luis for moving in on David's girl... My condolences to all the cast and crew who worked closely with Emilio for decades, as well as his "real" family. He was a wonderful actor and role model for generations and generations of children, and he will not be forgotten.
