ya I agree this is so far the best fan fiction I have ever read, you really captured the doom slayer really well. Also I dont know if you want to, or any body else would like it (maybe ask of there point of view) but there is a character in the doom universe that could act as the apprentice of the doom slayer. The name of this character has been given the name phobos. Hes been released as skins and bobble heads in doom 2016 and doom eternal but was a legit character in quake 3 in co-OP mode. His armor was replicated as the original doom marine armor but was orange. He an African american male who has trust issues due to the fact that his superiors left him to be killed be the demons so they can learn how they kill, But he survived. Although his age is unknown so you can probably change it to like 22. I saw blake looking at doomguy like a really good sandwich so I thought maybe instead she would like phobos, a character not equal to the doom guy but as muscular as him(not as strong though) and also blake has trust issues, phobos has trust issues. You probably aren't going to read this whole thing but oh well. Also I dont expect him to be in the story. I'm just saying that if you ever feel like you need another ship in this one there you go. Hes also has the old armor so he dont have enchanted armor like doom guy. Many people might not know this guy unless there strait up die hard fans. Lol cant wait for the next chapter. (Again if you dont like this character I legitimately understand. It may take our eyes off of doom guy even though he is our main focus) also yang x doomguy is the best ;p
