>>19310625>>19310710When GF made a fresh batch of new pokemon for Gen IV, they showed around some designs, got opinions, etc from a test audience. Either Lucario or something like Lucario which then became Lucario was found to be incredibly popular. It was then placed in its movie to get more feedback. It was popular, and Lucario became the mascot of Gen IV. I don't mind, he's one of my favorite pokes.
