A thought that came to mind after watching episode 17 of Xros Wars.
In the eventual adaption (or something close to it), what would Seth the ShadowWereGarurumon and Emmett the Myotismon be doing while Sparrowmon is risking life and wing?
Well, likely doing the same thing I'd imagine. They also love Nene (I can hear Seth saying, "But I love you MORE
!"), and potentially they also have a spine as opposed to the Monitormon and willing to turn their back on DarkKnightmon to save Nene (though Emmett may be hesitant to go against D-Knightmon at first).
While I don't want to overshadow X5, the thought came to mind that Seth and Emmett may also DigiXros with X4 for a little bit, perhaps quickly realizing that Taiki just wants to help unlike Sparrowmon. (Or they force/trick Taiki into DigiXrossing them, not sure yet.)
(Perhaps in order to make way for X4, Lucemon either catches X4V off guard and smacks him back into his component pieces, or Seth and Emmett deliberately cancle the Xros to make way for Sparrowmon.
Why he looks more vampirian? Eh, it looked pretty cool in my mind. I guess I was originally thinking of an 'evil' take on X4K.
Why there's a "Bat-Pickmon"? Malicious Melody functions similarly to Grisly Wing, but instead of bats, mutated Pickmon fly out of his cape instead.
...What? It makes perfect sense to me.
Pry one of the few Digimon designs I felt confortable on on the first sketch.
