If MapleStory could have a crossover with a TV Show...

Like I said before, I don't know anything about Adventure Time. I can't imagine, however, a simplistic comedy cartoon providing nearly enough hype.

While most episodes of Adventure Time might give that impression, there is in fact, a dark backstory behind it.

The land of "Ooo" is in fact, a post-apocalyptic Earth after a war devastated everything. Some episodes give us insight into this.

And of course, there is Ice King's backstory.
