I liked Takuya actually too. He was hotheaded without being insane about it. *cough Taichi/Tai and Daisuke/Davis cough*
My favorite characters are all in the Xros Wars series actually, including Hunters... despite Hunter's lack of development and weird ending. Everyone was interesting Taiki, Tagiru's rival Ryouma, Ren with his evil kind smile, the list goes on :D
I like Takuya the best but that's proably due to his season being the one I watched when I really got into Digimon.
I still have yet to finish Taiki's series xD
So who's your favorite over all character?
