Jinz is the girls new friend who goes to pokey oaks with them. He later gets his own spin off cartoon called Jinz where he lives somewhere safe but still in townsville with his Professor related father who has a gun for safety which Jinz always trys to eat.
Green Bane (from powerpuff z 3) looking hair red shirt black jacket jeans shoes that look exactly look the girls' (same thing with eyes just all black but still with the white shine).
His name is simulliar to the word "jinx" (pronounced GEE-Y-IN-KS) which means if you say something at the exact same time as someone else.
His idea was just random. (not sure how that is trivia)
