The OC is a character in Call of Duty Ghosts but they don't count him as a character in fanfiction. The character is Logan's best friend.

Logan was waking up after sleeping with Riley. He felt a person in his bed and became nervous. He looked to where Riley was laying and saw something unbelievable. It was a German Shepherd anthro. This anthro had a strong build like Merrick and was like 6ft and 6 in tall. What really caught his attention was that it looked like a half human version of Riley. He decided to wake up Riley. "Riley? Riley?" Logan whispered. Riley woke up and look at Logan but became confused when he saw Logan with a look that showed he was nervous. "Is that you." Logan asked. "Of course it's me." Riley thought then he realized he was in his anthro form. He sat up and said. "Logan. I can explain." Logan calm down when he realized this really was Riley. "What happened to you?" Logan asked curiously. "Well the think is...I'm immortal and so are you and the rest of the family and the Ghosts." Riley said. Logan was surprised to find out that kind of information, but what did it have to do with Riley being some kind of humanoid. "What does that have to do with this?" Logan asked. "Well immortal dogs like me havbe the ability to change into a anthro form and the ability of speech. I must have changed into this form when we were asleep." Riley explained. "So why didn't you tell us?" Logan asked. "Because I needed to show you when I proved that I was friendly. It's not everyday you find out you and your dog are immortal. I found out you and the others were immortal after comparing your hearts with mine. Immortals have the same kind of heart." Riley explained. Before Logan could say anything the door opened and outside the room was Elias. "Hesh? Is that youyou? What's with the costume?" Elias asked. "Dad it's no costume. It's Riley. Our Riley." Logan said. "Nice try boys but it's gonna take more than a costume to fool me." Elias stated not buying any of it. "Elias it's true. I am Riley. All three of us, Hesh, and the rest of the Ghosts are immortal and immortal canines like me have the ability to talk and change into an anthro form. Also immortal canines live human years which explains why I'm 35 like Logan when I was born in 1990." Riley explained walking up to Elias so the older man could have a better look. Before Elias could say anything he looked at Riley's features. His eyes went wide with shock. "So you're Riley and we're immortal?" Elias asked trying to take it all in. The anthro just nod. "Everyone has to know." Logan said as Logan got up. "You sure? I mean we can wait awhile." Logan said as he walked up to his friend. "I'm sure. After all you two already know." Riley said as he went to the rec room.

Once he walk in he saw Hesh, Keegan, Merrick, and KickKick sitting on the sofa. "Hey guys." Riley simply said. Hesh looked at his and said. "Sup Riley." He said before looking back at the TV then his eyes widen in realization. "Wait Riley?! Is that you?" Hesh asked in shock getting up from the sofa along with Merrick, Keegan, and Kick. "No it's John F. Kenndy. Of course it's me!" Riley shouted. The four Ghost were shock that their dog was half human and bigger and stronger. "How...how did this happen?" Kick asked. Riley folded them what he told Logan and Elias. They let the information settle before they look at Riley. "So all this time you were capable of all this?" Keegan asked. "Yes." Riley simply said. The Ghosts sit back down while Logan and Elias came in the room. "So Riley told you everything?" Elias asked. "Yeah" The four soldiers said in unison.

Here's the first chapter. I need time to come up with ideas. I'll update whenever possible.
