History:
Elena "Yo-Yo" Rodriguez is a Colombian citizen who underwent Terrigenesis during the Inhuman Outbreak and a S.H.I.E.L.D. operative. Believing her power to be a gift from God, Rodriguez used her new gift to fight corruptive elements within the Colombian political system, including the National Police of Colombia. This briefly put her into a conflict with S.H.I.E.L.D., but as they saw that Rodriguez was using her powers for good, they recruited her into the Secret Warriors. Seeking to use her gifts to protect the world, Rodriguez assisted in the battle against Hive and his army of brainwashed Inhumans, during which she was nearly killed while saving Alphonso Mackenzie from the Primitives. Agreeing to sign the Sokovia Accords, Rodriguez immediately went behind Director Jeffrey Mace's back in order to seek out Victor Ramon who had killed her cousin. Rodriguez found Ramon and stopped his weapons sale to the Watchdogs with the aid of Quake, whom she then agreed to assist in her own vigilante missions. Returning to S.H.I.E.L.D., Rodriguez assisted in the defeat of Eli Morrow with her teammates and started a relationship with Alphonso Mackenzie. Later, she joined the fight against Aida, her LMDs, as well as Anton Ivanov and his Watchdogs and entered the Framework to convince Mack, who stayed there, to leave before it was deleted, eventually succeeding. Soon after, Rodriguez and the rest of the team were sent to the year 2091 where Earth had been destroyed and the human survivors lived in the Lighthouse under a Kree rule. She and Mackenzie decided to stay in the station with the Inhuman Flint to help the people to stand against the Kree, while the rest of the team left to find a way back to the present. Before she returned to Earth, Rodriguez encountered a future version of herself who warned her about the events which would cause the apocalypse. While attempting to avert the destruction of Earth in the present, only to walk into a trap set by General Hale, Rodriguez lost both of her arms trying to save Mackenzie but later won cybernetic arms to replace her missing limbs. Rodriguez ultimately warned her colleagues about what her future self had told her: that trying to save Phil Coulson could result in the Destruction of Earth. This put her at odds with some of her teammates, notably Daisy Johnson, who refused to let Coulson die. However, Rodriguez's warning was eventually heeded by Coulson himself, leading to a S.H.I.E.L.D. victory over the now rogue Glenn Talbot. Rodriguez then remained with her S.H.I.E.L.D. teammates for new missions under Mackenzie's directorship.

Powers:
 Rodriguez gained the power to run and move at least 180 meters per second, being unable to be clearly noticed by the human eye and appearing as a blur. Her super speed lasts exactly the same amount of time as one of her heartbeats; after which she retrogrades back to her original position through any route possible, which happens regardless of her state, as she snapped back even after being affected by Lucio's paralyzing gaze. She used this speed to disarm and kidnap Alphonso Mackenzie and also to disarm several corrupt Colombian police, subdue HYDRA soldiers and to snag General Glenn Talbot's medals in a split second. Rodriguez cannot be seen on security cameras and she just seems to move forward slightly which is followed by what seems to be a glitch. Rodriguez can run faster than a bolt fired from the Peruvian 0-8-4. Rodriguez used her powers to place bombs on the roaches, and deliver blows to Daisy Johnson. She also used her speed to kill Ruby Hale after she absorbed 8% of the Gravitonium. However, she is not fast enough to catch bullets, as her attempt to do so caused her to be shot by Primitives. She is also not fast enough to outrun a cesium explosion, though she was able to avoid being engulfed completely. Rodriguez' powers could not compete against a Gravitonium-empowered Talbot's gravity fields, as evidenced when she tried to grab his son and was unable to get close, simply returning to her origin as soon as she encountered the field. The nature of her powers requiring her to retrograde to her original position has the potential to become disadvantageous, should something interfere with the pathway of her retrogradation there is the potential she will collide into it. Although, Rodriguez is largely able to mitigate this potential weakness as she is able to take various alternate pathways back to her original position.  When Rodriguez runs, she is able to see her surroundings move in a slowed down state due to her superhuman speed.  Rodriguez had enhanced momentum, which allowed her to enhance the force in her attacks, strikes, impacts and collisions, often propelling objects or people several feet, thats she used to compensate for her average human strength.  After losing both her arms to Ruby Hale's Ring Blades, Rodriguez obtained cybernetic arms which granted her additional powers to complement her natural Inhuman powers. However, the arms themselves were initially incompatible with her Inhuman powers; they overloaded her nervous system because they were not designed for extreme speeds. Leo Fitz recalibrated them shortly before the Siege of the Lighthouse, allowing her to use her Inhuman powers.  Thanks to Elena's cybernetic arms, she now possesses a certain degree of enhanced strength. She was strong enough to accidentally crush a metal drinking bottle, punch a heavy boxing bag several feets back, and was able to overpower Anton Ivanov's android body. She also used her strength to break a lock, lifted up a large shelf, and was able to carry a woman to safety during the Battle of Chicago.  Rodriguez speaks her native Spanish and English which she greatly improved upon being recruited by S.H.I.E.L.D. albeit still with a heavy Spanish accent.  Since being recruited by S.H.I.E.L.D. for the Secret Warriors initiative, Rodriguez was trained to combat. Her fighting skills enabled her to fight and destroy Anton Ivanov while he was using an enhanced android body, without the use of her powers. She was also able to hold her own against fellow agent Daisy Johnson.
