Sechs (AR-6) Maddening Grin
for being an andriod this guy seems a tad unbalanced, as judging by this pic which shows his typical expression (especially while fighting and slaughtering any and all in his path).
the artist even gives him sharp ass teeth like a shark or something- and yellow eyes like Inu Yasha! he's like the perfect mix between Inu Yasha and Vegeta he's right in between them I swear! maybe that's why I like him so much! Vegeta is too quiet and anti-social and Inu Yasha is too nice! But I love them anyway!!
Sechs is like smack dab in between them- mean and vicious and doesn't give a shit, but can converse with out people with no problem and just doesn't give a toss about anything!! ahh.. Sechs is soo cool!
