Skylanders Support

Since this is the recent endeavor that the Spyro franchise has undergone I wonder if it would be possible to do cross-title integregation. You'd think someone would decide to plug in the Portal of Power and see if the game will respond. Well, I thought about that and thought about how it could be handled.

4th Character
Maybe you want to import your own skylander and join the adventure in a 3d platformer beat 'em up or just go sparing. This sounds cool but there are some problems to overcome.
 * 1) All characters will have to be supported when it comes to Level & Quest design and data constraints.
 * 2) How characters would interact with each other.
 * 3) Spyro meeting himself... wait... scratch that.

Multiplayer Only
When it comes down to it, the majority of the single/co-op experience is designed with three characters with a specific set of abilities. However, this is not accounted for in Multiplayer arenas levels. You want Trigger Happy and Elora to go at it? Go ahead.

Cameo
You'll see them running around somewhere and possibly have an additional quest to give you. It's not much but it shows that the game acknowledges it. What in blazes will Skylanders Spyro do though?
