This is the primary antagonist for my video game "METONYMY". Check out his high poly model at the link down below.
Mister Mental acts as a chaotic antagonist who wants nothing more than to be free of his own pain. He has acted out in the past against Colin acting as a personification of Depression that overtakes the healthy parts of his mind but now that Colin has entered Sagacity himself, Mister Mental wants him to understand the torment he is going through. He does this in hopes to cure himself of that turmoil but also as a means of revenge against Colin.
Mister Mental is the subconscious voice that guides Colin through most of the story until eventually revealing himself and ultimately trying to kill Colin.
