There is a slew possibilities in regards to Alice Braga’s role in The Suicide Squad, save gossip of her Poison Ivy casting, as it appears that her role as Sol Soria is an original invention for the movie.
While it does sound somewhat unlikely as the reptilian beast is not confirmed to appear, it would be fascinating if SolSoria was seeking out Task Force X to find KIller Croc and avenge her father’s death.
However, a more knowledgeable DC fan may speculate that she is, like Ratcatcher 2 is rumored to be, either a gender-swapped version or relative of Juan Soria: a lesser-known character with a skeleton key hand who was eaten by Killer Croc not long after his first and last Suicide Squad mission in 2018.
