Oh oh oh! six! Cause it looks cool and I can see Doc the best for some odd reason. Wired eyes must stop being wired. D: But then again I'd have to go with Tigerlily with the digivole. so it's a draw between four and six.

green clashes with red...#1 xD
The green does seem to clash the the red. Reminds me of Christmas colors.
I'd choose #6 or #8.
