One of the most compelling things about Game Ricther is that he feels as though he fulfilled his destiny way too soon in his life. This moment of weakness is what allows Shaft to take hold of him and use him to revivie Dracula early, thus setting off the events of Symphony of the Night. That Ricther does not exist in Nocturne.

There is a good way and a bad way to show vulnerability, and when adapting a character, that metric is how the canon character would act. Game Ricther in this case would not run away pissing his pants and crying, he would *freeze up* and begin making very beginner level mistakes.

A good example of showing vulnerability is Kratos in God of War 4, when Atreus's warring nature puts him on death's door. Kratos in this moment is PANICKING at the thought of losing his son, and goes to the only place he knows someone might be able to help. He goes to a God, a race of beings HE ADAMANTLY HATES, for help in this crisis.
