In March 2019, when Team Flash needed a test subject for the meta-human cure that they recently devised, Lyla Michaels had them meet with Tanya, who explained her recent breakthroughs on working with Shay. They attempted to communicate, when Grodd used his abilities to make Shay take off the crown, and later, with the Flash having to non-consensually inject him with the cure, causing Shay to temporarily regain his human form. After this Grodd would obtain the crown and use it to defeat the Flash and XS. Until Shay volunteered to become King Shark once more. After King Shark defeated Grodd. They both returned to A.R.G.U.S. where King Shark and her would continue to talk and connect with each other.
