I'm only going to do fanart up to where the anime series is at ( to avoid spoilers since I've read all the manga too OTL)
From left to right
The " one with the nice ass" AKA female Titan
The " holy shit move out the way " AKA armored Titan
The really really really angry titan
The really really fucking huge titan AKA the colossal Titan
And the late for work titan.
*please... No spoilers, that should go without saying*
