Just to continue the discussion, I'm reading up on the idea of FALSE MENTOR.
Places cite The Big Bad Wolf as a false Mentor. He is clearly a Shapeshifter/Trickster archetype. But I also see the false mentor label as appropriate. Even so far as adopting the guise of Grandma, as opposed to a random stranger Little Red could have met on the way. I'd say this example, might be a stretch, as what is Little Red really learning for the Wolf?
Another example is Captain Beattey in Faranheit 451. He seems oddly unique. He is neither a Shapeshifter, nor a Trickster. He is never trying to mislead Montag. He simply holds beliefs counter to that of the reader. And continually provides the service of Mentor to the protagonist (Montag) which results in the protagonist being mislead.
Chris Vogler (of the Writer's Journey) also states that the hero can encounter a false Mentor. Someone who the hero relies on, but steers him in the wrong direction.
This is the archetype I believe Gekko to largely occupy. Much like The Big Bad Wolf, it also incorporates the Shapeshifter (which Scott is using as synonymous with Trickster) archetype.
Compare this to the role of say -- Burke in ALIENS. I think it'd be rash to call Burke a Mentor. He is clearly a Shapeshifter. Gekko on the other hand does provide the role of Mentor to Bud Fox in a way Burke doesn't to Ripley.
Thus, Gekko is a false Mentor and Burke is simply a Shapeshifter.
Love the debate. Really makes me think about narrative structure.
