In the most recent bombshells issue Jason todd appeared as a basque. Seeing how hispanic Jason seems to be a popular thing among his fans how likely is it that he will be made hispanic or latino in the main continuaty.

I don't think it's likely that will happen in main continuity.

When I understand the definition of these terms correctly basques aren't "latinos", and calling them "hispanic" is probably also kind of problematic.

I also don't see that the make him a full latino/hispanic, but something similar to the pre flashpoint Catwoman (who had an Irish father and a Cuban mother) could probably work.

aren't basques european?
