Never officially in the original onyesha au PPGZ. In PPGD Blossom is currently w/ Dexter (shown below) and the RRB had only a few pages about them when Butch fought XJ-9. But it does onyesha Boomer siku dreaming about Bubbles a lil bit. So as of right now, they've only coupled up in shabiki fiction and shabiki art. (the picture below is from PPGD done kwa Bleedman. Just to make it clear, I'm not trying to steal anyone's artwork)
I fucking hate this couple and Bleedman! Bleedman can suck a sack of dicks, shove them up his punda one kwa one, and get raped kwa a horse for all I care!
