Fan Casting DC’s Legion of Doom (2017)

The Revenge of Doom (Super Friends short): All 13 members of the Legion of Doom appear after getting back together, but only Lex Luthor, Sinestro and Solomon Grundy have dialogue. In this appearance, they salvaged the Hall of Doom disguised as construction workers with the cover-up that they were going to turn it into a museum. Batman and Robin came upon the "construction workers" and demanded to see their permit which they did having been obtained by the Department of Parks. When there was a mentioning that the Ion Engines were removed by the Super Friends which would've made it the first flying museum, the Dynamic Duo gets suspicious about the construction workers learning about the top secret operation as the lead construction worker claims that the info of that might've been leaked to the news. With the plot exposed, Lex Luthor and the Legion of Doom shed their disguises and capture Batman and Robin. After refurbishing the Legion of Doom and equipping it with new weapons, they have developed a crystallizing ray to immobilize Superman and Wonder Woman. Batman and Robin eventually escape, reverse the effects of the crystallizing ray on Superman and Wonder Woman, and apprehend the Legion of Doom.
