How about Ricky is the ex king, he was supposed to be killed but somehow managed to escape with everyone thinking he's dead.

Thunderous soldier is Kyros, who used to be some sort of champion of Riku kingdom, and Rebecca's father. He got turned into a toy while trying to protect Scarlet which is why no one remembers much about Kyros apart from the 'stories' that were recorded, leading him to be sort of a myth since no one remembers the toys.

Which also explains why a friggin toy still manages to kick so much ass, because he used to be a powerful human, and even as a toy he managed to teach Rebecca how to fight.
