Creator Diego Molano worked on As Meninas Superpoderosas (2016) and OK K.O.! Vamos ser Heróis (2017) before Victor & Valentino.
The character Valentino is spoofed and inspired of a "White Washed Mexican."
From the original 2016 short the show is based off of, Rico Rodriguez was the original voice of Valentino. And the character of Victor was not so remorseful about his brother facing death, which is what caused the rumour that they were half brothers who hated each other with vengeance. They are not half brothers but full blooded.
