This is also my favorite specialist in black ops 3
As an orphan on the streets of Rio De Janeiro's Rocinha favela, Alessandra 'Les' Castillo survived on her sharp eye and keen wits.
Given an education in one of the city's international missions, she spent her spare time traversing rooftop to rooftop, watching the people moving in the streets below, noticing patterns and learning how to predict their movements.
After joining the Brazilian Army at 18, her agility and observational skills quickly earned her a place in the "Bda Op Esp", the Special Forces.
Now an advance scout, she stalks the battlefield, tracking down her prey before destroying it with lethal accuracy.Outrider's biography
According to her transmissions and her biography, Alessandra Castilo grew up on the streets of one of Brazil's most infamous favelas. When she was a young adult (an age considered to be old in the favela), she began following a group of rich gangsters. While in pursuit, she accidentally ended up in one of the worst parts of the favela. Once discovered by gang members, a chase ensured, but she managed to run into a squad of soldiers in the Brazil army. The squad leader complimented Alessandra on her recon skills, and this incentive inspired her to join the army when she turned 18. Once in the military, she joined special forces and took the callsign Outrider.
Outrider is the least cybernetically enhanced specialist, having no visible cybernetics, except for a single augmented arm on some skins. She seems to get along with most specialists, minus Prophet and Seraph, asking the former what has he done to himself and telling the latter to "chill out".
And her main weapon is a bow called the sparrow witch fires arrows that explode!
