While I haven't watched anything straight from it...my favorite part of Black Sun that I've watched clips of is Shadow Moons henshin pose

I love how simple it is: how its basically Black's mirrored and...I dunno slightly more sinister

aat least thats how it feels

(also i love they decided to jusy outright keep Black's for Black Sun instead of updating it along with the belt

Also...the belts. Apparently the commercial version will move JUST LIKE in the show...Im guessing through motion/voice detection?
