OF COURSE!

They're dreams! Why would you restrict yourself? You could use the thread to try out super-strong Pokemon from a wide pool, mixing and matching up combinations for a potential team-building exercise (literally). More challenging sidequests should feature stronger foes, of course, but that doesn't mean the heroes of these don't pack a punch of their own. While I'm at it, more challenging sidequests do not equal the player character having a super-strong arsenal, or being able to USE that super-strong arsenal. One I had in mind was a brutal obstacle course of battles that require you to figure out the best possible route in all battles, or you fail immediately, done by the biggest bada** in all of GCeA, severely lacking in power and skill.

They might not also be in situations typical in GCeA. Another one of my ideas had Craig and some other guy dream they'er the protagonists-Hero and partner respectively-of the PMD Explorers series, going through the first dungeon!
