Buckle up and grab a notepad, this is gonna be a lot of explaining. (also I don’t know the names of some of these people, bear with me)
This meme references to Part 4 of Jojo’s Bizarre Adventure, also known as Diamond is Unbreakable. The city shown in the background references to Morioh, a town in S-city and M-prefecture. The blonde man at the top middle of the image represents Kira Yoshikage, the main antagonist of Part 4. The cat with pink skin and eyes is a homage to Kira’s stand, Killer Queen. From left to right comes Jotaro Kujo from Part 3, who makes a reappearance and is portrayed by a man in a trench coat similar to Jotaro’s updated fashion choices in his reappearance. The purple man behind him is Jotaro’s stand, Star Platinum. Next to ‘Jotaro’ is Dwayne ‘the Rock’ Johnson, aka Okuyasu Nijimura, Josuke’s best friend and low IQ stand user, behind Dwayne (Okuyasu) is Patrick colored as a light grey, this is in reference to Okuyasu’s stand, ‘The Hand’, a possibly overpowered stand had it not be for his slow witted mind. In the middle is Danny Zuko, a popular character from the 1978 movie ‘Grease’. He is in reference to the main character of Part 4, the next Jojo of the Joestar family tree, Josuke Higashikata. Josuke’s stand is shown as Fix it Felix Jr. from ‘Wreck it Ralph’ turned pink. Felix represents Josuke’s stand, Crazy Diamond. A stand that can repair almost anything it is commanded to. Next to Josuke is a small male, who represents Koichi Hirose, a man of small stature who has Eminem changed to green behind him to represent his stand ‘Echoes’. Last but certainly not least, is Bob Ross, a famous painter who is included to depict Rohan Kishibe, a manga artist who holds the power of a stand called ‘Heaven’s Door’, it allows him to transform anyone into a book to which he can read for inspiration.
