Lucario was 18 but she acts like she just turned 12. She was your first Pokemon and you had her since she was a riolu but when she evolved she started the teasing, the pranks, and embarrassing you in front of girls. You had just turned 18 and you were out camping with her when she walked out of her tent and tapped you on the shoulder. You expected her to pull another prank but when you turned around... Her face was pouty and blushing... And you can see she was wearing a hoodie... Only a hoodie
