oooooh I love me some Nara men. XD THANK YOU SO MUCH FOR THIS PICTURE. Daddy Nara is insanely cool. I often wish they would go more into the previous generation of the InoShikaCho formation. The brief interplay we've seem between the three seem like they would be hilarious and awesome.
Early in the series as it was released in Japan, Shikatou became the fanon name for Shikamaru's father. Only later was his real name revealed. Thus, you'll see some of the archived fanart referring to him as Shikatou.
Wow, great job on Shika's dad. Looking at this I got a super strong Mugen vibe from Samurai Champloo... even though Mugen has cropped hair. The body and attitude just screams Mugen to me. Awesome work, I love it.
