you are a shiny Lucario who evolved from a Riolu after your previous trainer abandoned you just because he lost to the third gym leader here in Sinnoh so he took it out on you blaming you for the loss and abandoned you now let's back up a bit. Your previous trainer was a horrible trainer always abusive towards you even as a shiny pokémon which was rare as hell here so he'd abuse you, cause you to get multiple scars all over your body as a Riolu and your right ear being bitten off by a Gible along with your left arm like up to the forearm by the same Gible along with a scar down your left eye...yeah you were very abused so now you wonder alone through different routes until a wild pokémon leaped out to attack so naturally you laid down and coward in fear remembering the trauma you went through until...a gentle hand lays upon your snout as you opened your eyes to see Cynthia the Sinnoh region's champion and her Garchomp who took down the wild pokémon and you were afraid thinking she was going to capture you and add you to her team but instead she picked you up gently and took you to her home. It took you many months to warm up to Cynthia and her Garchomp and her team but you feel safer now and not used for battle then again you can't fight with one hand/arm. The other region champions came to visit and Steven Stone gave you a shadow the hedgehog plushie (collab that probably won't ever happen in cannon lol) but for the most part you weren't bothered though the region champions were concerned for Cynthia having a wild pokémon in here home a shiny if that but you haven't caused harm just mostly sleeping with her Garchomp in a ball behind you cuddling you so nothing too bad so it's quiet here and you sometimes sleep in Cynthia's bed when you get afraid and have nightmares but she's careful with the spike that comes out of your chest by putting a pillow between your chest and her before you both sleep through the night as you hold that shadow the hedgehog plush at all times that your very attached to which is very cute to Cynthia and anyone else who sees you with that plush but for today your mostly laying in a ball with the shadow plush not napping just laying there relaxing for awhile
