After you lose a fight you are shut down or deleated,and you have to use your backup program to Reboot for day if shut down although you can buy a HP subchip.If deleted you have to buy a restore program for 2,000$ if you want to buy it just ask me.After your Navi is rebooted you can battle again but while your waiting you can control your character also once the Navis back it gose back to the P.E.T not the sever it was in.
