In late 2019, Harry threw the first annual Six Invitational at the Stadium to serve as the ultimate test for Rainbow Operators. She also developed the SIM-SUIT to provide real-time simulated feedback of any damage an Operator may receive during exercises. Álvarez oversaw the construction of Rainbow's new state-of-the-art training facility known as the Stadium. The continued global threat of terrorism eventually led Harry to conceive The Program. She also collaborated with Lera "Finka" Melnikova and Monika "IQ" Weiss to refine Collinn "Warden" McKinley's Smart Glasses. These evaluations resulted in several noticeable improvements such as adding a ballistic shield to Alexsandr "Tachanka" Senaviev's mounted LMG. With Harry Pandey's promotion as the new Director of Rainbow in 2019, he tasked Álvarez with conducting evaluations of all Operator equipment. The ordeal resulted in a rivalry with Eliza "Ash" Cohen but also inspired Álvarez to design a specialized laminated glass that she dubbed "Black Mirror". She later worked with Emmanuelle "Twitch" Pichon to develop the CCE Shield for Morowa "Clash" Evans.ĭuring Operation Blue Orion, Álvarez was forced to improvise a panic room at the Embassy of Spain in Tel Aviv. She was later added to Rainbow's combat roster so that she could better test her developments and improvements under field conditions. In 2017, Álvarez accepted a position by Harry Pandey to be Rainbow's Director of Research and Development. While with the GEO, she developed and tested bulletproof materials on the field as well as enhancing bridging vehicles. Álvarez was later encouraged to join the Grupo Especial de Operaciones (GEO) and ended up beating more than 100 other recruits for the coveted position. She saw the need for better equipment and developed new bullet proof materials to protect her teammates while on operations.
Proving to have stellar strength, endurance and knowledge of vehicles sparked her progress in the ballistic field. Instilled with a strong sense of justice and an obligation to serve, Álvarez joined the Cuerpo Nacional de Policía. She started working alongside her father in his repair shop which helped form her intricate understanding of machinery and prompted her to study mechanical engineering and metallurgy at university. Álvarez later found her purpose working for the family business. Her sister dressed her doll up and had tea parties while Álvarez took a knife and cut it open to see how it worked. When they were both young, Álvarez and her sister both received a doll. Abandoned by her mother at birth, Elena and her sister were raised by their father in Madrid, alongside with a grandmother as a maternal figure.
