Do they still count as "gijinka" if they're not actually human?
Anyway, here's Final Destination and Battlefield! FD is based off the Melee incarnation, whereas Battlefield takes most of its inspiration from the Wii U and 3DS versions. I tried to go with fairly androgynous designs, since I don't think Smash Bros stages actually have genders.
Originally I was trying to ape the Ghost Trick style, but I did such a lousy job it almost comes off looking like something totally unique instead.
I was going to do a sort of series of these, but these are the only ones that I feel came out solid enough to share!
