Perhaps any Mexican or Spanish linguists can shed more light? Is this accurate enough?

By thus, during 2017 Mexican plan to bring to market a line based on this new production, ensuring that it will be a major release.
he has done a great job dubbing villians and surely he will shine with this amazing character. 
Also, the original DB, DBZ and GT dubs were all originally translated from Japanese to Spanish. Their scripts were extremely accurate and they hold up as some of the most accurate dubs those three ever got. The first half of Kai was dubbed into Spanish using scripts from Funimation and it was hated severely. To compensate for having to use materials from Funimation, they decided to use their own names and terms instead of Funi's when they dubbed it. I guess that's not the case this time around. It got a lot of people, including me, riled up when they heard that "Destructo Disc" made it in there. So maybe they are using Funi materials for the second half of Kai. I just hope that's not the case for Super.
