My theory: Gladiator Ricky is Rebecca's grandfather the former king, and Thunder Soldier is either Kyros or a loyal guard/soldier of the kingdom (similar to Chaka and Pell). Also possible is that Ricky is both Kyros and grandpa former king, and Thunder Soldier is just a guard/soldier/knight/Chaka-Pell-like character.
