Ash's Lucario

Ash's Lucario is an Fighting/Steel-type Pokemon obtained by Ash as an egg. The egg was entrusted to Ash's care by Nurse Joy after the Pokemon inside the egg chose Ash as his trainer. The egg later hatched into a Riolu and Riolu chose Ash as his trainer. Ash and Riolu formed a bond together. Team Rocket tried to steal him as an Riolu once. During Ash's time in the Galar Region while fighting Chairman Rose, when Ash and Pikachu were in danger of being crushed, Riolu stepped in to protect his friends and he evolved into a Lucario while fighting. Ash's Lucario is loyal to his trainer and cares for him deeply. He like Ash is very protective of Ash's Pikachu shown when he and Goh's Cinderace mistook Team Rocket's robotic Pikachu for Ash's Pikachu and tried to save it.
