At the time Soto was born, the fourth son, his parents were struggling financially, with his father working as a garbage man and his mother as a house cleaner. Soto grew up in a very religious Pentecostal family, attending church with his family weekly. Soto started wrestling in junior high 8th grade and also played pop warner football. Soto went to Porterville High School in California where he was on the wrestling team and won a California state title. Soto got an athletic scholarship to Iowa Central Community College was a 2x NJCAA All-American. There Soto wrestled with Jon Jones, Colby Covington and fellow Mexican American Cain Velasquez.

Soto began training mixed martial arts after meeting another fighter who agreed to train him in his garage. Soto began training and took his first fight at a Gladiator Challenge event. Soto won the fight midway in the first round via technical knockout. Soto compiled a 4–0 record before getting signed to Bellator Fighting Championships.

Soto joined Bellator by entering their Season One Featherweight Tournament. Soto made his debut defeating Ben Greer at Bellator 1.

In Soto's semi-final fight, which took place May 8 at Bellator 6, he dominated Wilson Reis from the opening bell with impeccable takedown defense and superior striking. Despite being a Brazilian Jiu-Jitsu black belt and the only EliteXC Featherweight Champion, Reis could never get the fight to the ground.

Soto advanced to the Bellator Featherweight Finals and took on Yahir Reyes. Soto won the fight by submission in the second round and became the first Bellator Featherweight Champion. A few days before the championships, Soto cut his eyelid while wrestling during a warm-up and had to go to the hospital. Knowing stitches were not an option, he and his friends went to a beauty parlor to have the cut covered with make-up. While the doctor was inspecting Soto, his camp made sure to crack jokes and distract the specialist from noticing the cut over his eye.

At Bellator 19, Soto fought Diego Saraiva in a "Super Fight". Soto won the fight after cage side doctors said Saraiva was unable to continue because of a cut on his forehead.

Soto had his first title defense in the third season, taking on the winner of the Season Two Featherweight Tournament, Joe Warren. Following a dominant first round Soto was knocked unconscious by Warren at 0:33 of the second round. In the fight, Soto suffered a detached retina and was forced to stay away from fighting for nearly a year.
