D: dont be mad at meh... Besides, if you wanna get technical, everyone has chakra because it's BLOOD, and who said it was Naruto-based? And if anyone really could use chakra, don't you think a Lucario would? O.o I never said he was immortal, but consider this: An angel, someone who has already died bofore... Silver has lived many different lifetimes, taking different mortal forms each time. When he dies, he is born somewhere else... Plus I'm not copying your character, and you can't literally be the only one with experience in using blood energy... Everyone has it, only few know how to control it. A wise Lucario would most likely have this ability... Silver's not immortal, he's just been through many lifetimes.
