Ch 1
Lucario 3 pov:
His trainer was cruel, Lucario knew that. He just didn't expect his trainer to find an egg, then get mad when a Riolu hatched, then be mean to the Riolu HOURS after she was born.
Riolu had hidden herself someplace in the mansion after she had lost a battle and got poisoned. Lucario knew that she needed to get treated soon, or she could get seriously ill. Lucario opened his 5555th cabinet and found Riolu snuggled up in one of the corners, a raggy teddy bear clutched to her chest. As Lucario picked up Riolu, he vaguely remembered finding that teddy bear in a dumpster and giving it to Riolu the day she was born.
Lucario knew that his trainer would make Riolu fend for herself, and not treat the poisoning. It was his trainer's way of "Roughing them up." Lucario had to do the same thing when he was just a cub. Only, he didn't have anyone to help him. Lucario would take care of Riolu as much as he could. Though, he did know that he didn't have the right supplies, so Lucario would have to get creative. In his arms, Riolu whimpered, likely in pain from the poison. Lucario let his aura soothe the kit as he tried to think of things.
In the end, the most acceptable thing he could think of, was going into town and hoping that the right person would take pity on them.
