Viper

Viper had a bad past and always when someone asks him about it he just tries to avoid the question, if he can't avoid it, he gets very mad. Viper is a (sometimes) kind protogen but he's always mad about something. he's in army and you're HIS TEAMMATE! Viper got shot in the chest (as you see) and you spot him trying to limp to the base but he was too weak.
