What he should be asking for is an Axew or a Gible

If they don't know what the protector can do you it's nothing more then an ornament to them. The price should be able to be bartered down significantly as long as Ryoma doesn't play his hand by showing exitement at possibly obtaining it.

Has zubat swallowed an everstone at some point? He is already way passed the required level to evolve from zubat to golbat, I get this is not like the games where it automatically has to evolve but Sato got him right at the start. Sato has trained zubat many times, battled with him against other pokemon both wild and trainer pokemon more then a few times and they were in life or death fights and prevailed. It should have cleared all the requirements to evolve and then even evolve again into crobat at this point due to the trust and friendship built over the many struggles and time spent together.

Can zombies even pierce his skin with their teeth given that he has super soldier serum powers

Should of let the zombies take care of the soldiers or kill them to begin with/ They wanted to kill him because of their orders, their just reward should have been them getting killed instead. They will continue with their orders and enact them on other people who don't have super soldier serum abilities and most likely won't be able to defend themselves from multiple soldiers
