Manny learns the shocking truth: his mother, Maria, was… a superhero! And when Manny finds her abandoned Glove of Power, Maria transforms into her long-abandoned identity: "Plata Peligrosa"! But she becomes so obsessed by fighting super villains that she breaks every villain out of jail to fight with them!
Maria Rivera was once a superhero and got her mystic item of power at a college party.
Her experience of her former superhero life is what caused her to enter a hyperventilation state.
During Maria Rivera's flashback you can see a younger version of Frida's parents, her mother looks similar to the present but Emiliano Suárez is sporting a light blue mohawk and leather jacket. Showing that he dyes his hair black. Their hair is naturally blue and that he was once a punk rocker in the past.
When Manny (as El Tigre) opens up the chest containing the glove, his eyes are brown (which he normally has in his civilian form), instead of green in a single scene.
