Yeah, and he doesn't even have a Spanish Wikipedia page! His successor Uaxaclajuun Ub'aah K'awiil seems to have a lot more known about him. I suppose he was just chosen because he has a cool nickname.
He does have a suspiciously too informative Ukrainian page. I mean, it gives his exact birth and death dates. It does not, however, mention at all that he was named "Smoke Jaguar". It does give links to sources in English, though.
