Griffin is the main antagonist in the novel The Invisible Man and its following adaptations. He creates a potion that can make him invisible, but in the cost of losing his sanity.
In the adventure that the invisible man proceeds to relate in the first person ('T'), his voice changes over time from that of a naive young man, to someone who is clearly more responsible though still confused, to a person willing to deal with the world whatever the risks.
