There is a saying that Gengar is actually the shadow of Pixar. The reason is that Gengar and Picosey are not only very similar in appearance, but also very similar in weight and height. Picosey's height 1.3m weighs 40kg, Gengar's height 1.5m weighs 40.5kg, Picosey is a general lineage, and Gengar is a ghost lineage. Their skills can't attack each other, so urban legends also use this to explain that Pixii can't attack its shadow and its shadow can't attack it. But in fact, Gengar has two attributes: poison and ghost, so he can always attack Pixii with his own skills. In the sixth generation, Pixii became a demon clan, which broke the urban legend.
