Jacky is a brash and confident young man hailing from San Francisco that manages to keep his head cool in any situation he finds himself in. He is an expert martial artist and practices Bruce Lee's famous Jeet Kune Do style; however, this is only a hobby for him, as his true passion is in racing. He works as a successful race car driver that frequents the Indianapolis 500 and is known for revolving his life around speed, considering himself to be "faster than lighting", a motto that earned him the nickname of the Blue Flash. Outside of his career, Jacky is very protective of his younger sister Sarah, with it being his main reason to fight in the series.
During the 1990 Indianapolis 500, Jacky gets severely injured in an accident and spends two years in an intense rehabilitation program. At the same time, Sarah is kidnapped by a mysterious group known as Judgement 6, an organization with a deep hatred for the wealthy Bryant family who she suspects is the instigator of the mysterious circumstances behind his accident, and thus began investigating into their dealings. In pursuit of her kidnappers, Jacky enters the newly formed World Fighting Tournament, which is sponsored by Judgement 6. During the championship, Jacky faces off against his now brainwashed sister, but ultimately loses.

In between tournaments, Jacky returned home to hone his skills, eventually becoming an instructor in Jeet Kune Do. Meanwhile, Judgement 6 trained Sarah further, turning her into a ruthless killing machine. Both partake in the second World Fighting Tournament with their own goals; Jacky wants a second attempt to save his sister, while Sarah is programmed to kill her brother. In the aftermath, though Jacky forfeits the tournament, he is able to successfully rescue Sarah.

Though Sarah was rescued, Jacky's efforts to undo her brainwashing result in her total loss of memory. Feeling uncomfortable about staying with someone she didn't know, Sarah moves to her own apartment in New York. Despite being separated, Jacky still kept tabs on her, which leads to him learning of her intentions to join the 3rd World Fighting Tournament in the hopes that she can regain her memories. Ever the protective brother, Jacky also enters to protect her. Though he loses yet again, Jacky has no qualms about being defeated as Sarah was able to regain her memories during the championship.
Virtua Fighter 4
With Sarah having regained her memories, Jacky returned to his racing career full-time, seeing as he no longer had a reason to continue fighting after placing Sarah under the protection of Vanessa Lewis, a member of the Bryant family's special forces. However, Jacky soon discovers that most of his potential sponsors are getting killed by an assassin under orders from Judgement 6. He shortly receives an invitation to the 4th tournament, with a direct threat by the group stating that they will kill more sponsors until none remain if he does not partake in the competition. Furious, Jacky restarts his training once again in order to finally take down Judgement 6 once and for all. However, with Jacky distracted with his training, it left Sarah vulnerable as the organization kidnaps Vanessa. At the tournament, though Jacky was unable to completely destroy Judgement 6, he still manages to rescue Vanessa and defeat the killer, Goh Hinogami.
Virtua Fighter 5
Jacky's anger towards Judgement 6 had not fully subsided, as Vanessa had now suffered dissociative amnesia as a result of the trauma she received when kidnapped. Combined with their tampering of his racing career, Jacky had enough and was committed to destroying the organization that tried to ruin his life at every turn. At that moment, the invitation for the 5th tournament came, and he joined once again.
A costume for the Mii Brawler modeled after Jacky Bryant was made available as a part of the Wave 2 batch of DLC costumes. The design is specifically taken from his appearance in Virtua Fighter 5, where he wears a leather jacket
- The costume being modeled after Jacky's design in Virtua Fighter 5, which is currently the most recent entry in the series, is most likely intentionally made to be the direct opposite of the Akira Yuki costume, which is modeled after the original polygonal model from the first game.
- Jacky's appearance in Smash is the second time he, fellow Sega character Sonic, and Banjo & Kazooie have appeared together following Sonic & Sega All-Stars Racing.
- Jacky's appearances in trailers make references to the Virtua Fighter series:
- In the "Mii Fighters Suit Up for Wave 2" trailer for Super Smash Bros. for Nintendo 3DS and Wii U, the Jacky costume can be seen fighting Zero Suit Samus, who is possibly meant to be a stand-in for Sarah Bryant as both look similar.
- In the "Mii Fighter Costumes - Round 4" trailer for Super Smash Bros. Ultimate, both the Jacky and Akira costumes fight a metal Mii Brawler, who is meant to reference Dural, a female cyborg who is the main antagonist of the series.
