Adventure Time Character Archetypes With Evidence?

Episodes where Jake gave Finn Advice: I already have Burning Low. 或者 when any of Jake's abilities was really helpful 或者 necessary. I'm trying to prove that Jake falls into the Mentor Archetype.

I need to know if anybody sees Marceline as the Trickster Archetype, (The Wise Full) and if so, give me episode 或者 quote evidence of how.

I need to know if anybody sees The Lich as the Shadow Archetype (Represents our Darkest Desire, Untapped Resources, 或者 Rejected Qualities), again with episode 或者 quote evidence.

I need to see if Any of 你 see the Ice King as the Shape Shifter (Character who “changes appearance” to disrupt the adventure)
 ---I know a lot of 你 are going to argue that Jake is the Shape Shifter, but I think I see him 更多 as the Mentor, if 你 disagree, provide evidence, please. And provide an alternative archetype for the Ice King.

And do any of 你 see Princess Bubblegum as the Herald Archetype (Issues challenges and announces coming of significant change - Gets the story rolling)?

One 更多 thing? Who is the Threshold Guardian? This is my hardest one to decide.
