Santos Escobar is teasing a possible main roster run and WrestleMania Match.
Appearing at the WrestleMania 39 Launch Party alongside fellow "NXT" star Roxanne Perez and recent Performance Center signee Valerie Loureda, Escobar heavily teased his jump to the main roster along with the rest of Legado del Fantasma.
"WrestleMania is the Grandest Stage of Them All," Escobar said. "The Showcase of the Immortals. Do you know what I represent? I represent mi familia latina. I represent mi familia Mexicana and I represent lucha libre, which means that WrestleMania next year's WrestleMania might just get grander because Santos Escobar and Legado del Fantasma might just make our WrestleMania debut and call this party Santos Mania!"
On August 14, 2019, Alcantar signed a contract with WWE. During one of the first weeks while training at the WWE Performance Center, Alcantar suffered a knee injury that prevented him from wrestling for several months. He made his in-ring debut under his real name for NXT on February 15, 2020, teaming with Raul Mendoza to defeat Lewis Howley and Sam Stoker on a show in Fort Pierce, Florida.
In the finals Fantasma defeated Drake Maverick to become Cruiserweight Champion for the first time, as well as winning his first championship in WWE.
After getting assaulted by D'Angelo Family, Escobar was hospitalized and the other members of Legado began working with the D'Angelo Family. On the August 2 episode of NXT, Escobar would return and cost D'Angelo and Stacks their title match against The Creed Brothers signaling that their alliance has come to an end.
