未经玩家许可，DM可以使用受版权保护的PC吗？

A player owns the copyright on their character as long as that character meets copyright criteria and was featured in something before being in the campaign, such as a backstory or drawing. This has already been checked and confirmed by a legal professional. My question, with that information in mind, is: With the copyright being held by the player, can the DM use that character as an NPC in a campaign without the player's permission or knowledge if the player is not available for that session or that particular campaign? If the player doesn't approve of their character being used in a certain way by the DM but they use them anyway does this infringe on copyright? If the character is then used in a different game can the player disregard something they did not give permission for happening to their character in the first game?
