A pokemon's species is determined by the mother. If they're different species, they'd have to have different mothers... which makes them half-brothers. Perfectly reasonable though, considering lion prides do have multiple females.
(And Scar looks way cooler as a Luxray anyway ^_^)
That's exactly my point! In Pokemon, a baby's species is determined by the mother only. A Pokemon can only be the same species of the mother, barring Ditto. If we assume their father is a Pyroar, then Mufasa's mother is obviously another Pyroar. However, since Skar is a Luxray, his mother HAS to be a Luxray as well. They could still have the same father, this unnamed Pyroar, but they can't have the same mother. Ergo, they're half brothers.
Thanks for the inspiration! :-D I’m not sure by some pokémon for »The Jungle Book«. My first idea was, that King Louie has to be a slaking. And his minions are Monfernos. Shere Khan has to be a Arcanine but it’s not a tiger, it’s not even a cat. Just because Baloo ist black, doesn’t mean the pokémon has to be black to. I think I stay with Ursaring. Ekans, Serperior and Seviper are good choices for the snake, but I’m not sure, which one matches perfect. And than we have Bagheera. Liepard or Persian, what fits better?
