I've been going through looking for any Warrior U content since I saw the /co/ thread. It's mostly all RC9GN, Osomatsu and Ninjago. So don't get your hopes up for Kick Buttowski.
Her pseudonym on deviant art was 'hot-choc' if you wanna scourer google images for any surviving stuff re-posted by russians/koreans.
I wish I'd just backed up that deviant art when I had the chance. rip. Also hi warrior u peeps, i love you and it's great to see you here at the dead end of the internet.
