[Guilmon and a shotgun]

Or it's possible that tamers was the very first chronologically and since they talked about actually creating the digimon and the digital world. Also in tamers, there were all four of the sovereigns, however in the other seasons, mainly 1 and 2, only azulongmon appeared, if the digital world was threatened that badly don't you think the other three would show up unless they couldn't?

Thats true, but how would you explain the strong presence of Digimon as a franchise in 03, but suddenly less abundant in Adventure? Surely Digimon fighting in downtown tokyo would have done SOMETHING to the sale of Digimon products and surely even the card slashing technique would still be used by Taichi and co.

I'm with the theory that Tamers was set in an alternative universe to Adventure, but it would be pretty awesome too if the digital world was the bridge between the universes; the fanfiction and art generated, if that statement was released from Bandai themselves, could build us a castle, upon a mountain, upon a disc, upon 4 elephants upon a sea turtle.

I need to stop reading Terry Pratchet
