Bwahahaaa bowz is back! XD I also gave him a bit of a new look! I drew this pic back in May of this year, not actually intending to wait til august to post it- but months passed and I never shared it, so I'll consider it my bowser day pic for this year!
His outfit is a mix of the Dennis Hopper King Koopa jacket from the 1993 film/elements from the costume concept art of Arnold Schwarzenegger as King Koopa when he was in talks to play him in said movie(We were robbed as far as the costume/prosthetics goes, cause those concepts are so cool ;__; ), and then based the colors of his outfit on the classic Bowser from old official art when he was grey-blue!
