Though he is somewhat able to restore the timeline, this creates new threats, including the god-like speedster Savitar as well as Killer Frost who both have grudges against Barry. When he accidentally travels to the future and sees Iris killed by Savitar, Barry is desperate to change the future to prevent that from happening by working with Vibe, Wally West and Jay Garrick. He learns Savitar is a future version of himself. After saving Iris and defeating Savitar, Barry takes his place in the Speed Force in order to repent for his creation of Flashpoint.

However, private detective Ralph Dibny uses shapeshifting power to help clear Barry of all charges. Following the Thinker's defeat, the team is approached by Nora West-Allen, Barry and Iris's daughter from the future. In the fifth season, Nora arrives from the future, wanting to change the events that lead to Barry's disappearance in the future. However, Nora's presence has altered the timeline and unleashed the serial killer Cicada bent on killing metahumans.

Barry gets the idea to create an artificial Speed Force to save his speed. Barry eventually develops an artificial Speed Force and finishes his fight with Mirror Monarch before dealing with the emergence of several new Forces, the Strength, Still and Sage forces, that were born by Barry and Iris recreating the Speed Force. Trouble soon ensues when the Speed Force goes mad and begins to threaten the city but Barry is able to tame it.

Possible future In a possible future, Barry as the Flash is one of the several heroes remembered in the era called the "Age of Heroes". Sometime before 2032, the Flash Museum was built to honor Barry and Team Flash for their heroics. The museum included exhibits for Barry's old enemies; including Reverse-Flash, Zoom, Savitar, DeVoe and Cicada.

Barry's suit as the Flash is altered and upgraded every season. The suit is designed by Cisco Ramon and its original design was intended as a uniform for firefighters. The suit during the first season was a modernised version of the traditional Flash suit with a matching dark maroon colored helmet, which features the same maroon emblem and gold lightning symbol as the suit does. During the second season minor changes were made to the suit, the alteration being the background color of the emblem is now white with a gold lightning symbol which is more true to the comics. Besides the alteration of the emblem in second season, there appears to only minor changes made throughout the three seasons. The suit in the fourth season appears to be a brighter red, with added leather paddings and golden accents. The fifth season made one of the most significant changes, that is the removal of the chin strap and switching the fabric softer more body fitting look, created by Ryan Choi, in the future. The suit in the sixth season is fairly similar to though now with gold piping along the torso and an entirely new cowl which features the return of the chinstrap as well as modified ear pieces designed to look more like the classic Hermes wings from the comics. The seventh season sees the Cowl to have nanotech for easier removal. The eighth season has the suit upgraded with the Golden Boots straight from the comics. ==Relationships==

Versions from other Earths • Barry Allen of Earth-2 (also played by Gustin) is a normal human who is a CSI at the Central City Police Department and a PhD graduate, married to Iris but despised by his father-in-law. • Barry Allen of Earth-90 is played by John Wesley Shipp. • Ezra Miller's Barry Allen from an undesignated Earth met Earth-1 Barry in the Speed Force during "Crisis on Infinite Earths". Savitar Gustin also was Savitar, an evil, scarred version of Allen who is season 3's main villain. Savitar is essentially Barry embracing his dark side. Savitar's origins are a predestination paradox as he's a temporal duplicate of Barry's future self using time travel for Savitar's defeat. Afterwards, the time remnant is spared but shunned for being an aberration and goes back in time to set in motion events that led to his own creation. He named himself after the Hindu god of motion who is "chronologically" the multiverse's first metahuman with speed. Long-held myths referenced Savitar throughout the multiverse, which even Jay believed, resulted in a cult that worshipped him. From his prison in the Speed Force, Savitar manipulates Julian Albert into acquiring the Philosopher's Stone so Doctor Alchemy can re-empower metahumans from the Flashpoint timeline. Savitar manipulates Kid Flash into freeing him from his prison, and convinces Killer Frost to be his personal enforcer. Savitar reveals his true identity to Barry, forcing his original self to confront his own dark impulses and temptations. Savitar's plan of Iris's murder (which would lead to his own creation) is ruined with the sacrifice of H.R. To save himself, Savitar manipulates Vibe to fragment himself throughout all of time and then goad his original self to give in to dark impulses. However, both efforts are foiled by Team Flash and Savitar is erased from existence after being shot by Iris. Past versions of Savitar make cameo appearances during the fifth and nine seasons. ==In other media==

• Fortnite Battle Royale features a skin using the Arrowverse version of Barry Allen. • After the first screening of the DC Extended Universe (DCEU) film The Flash (2023) to the attendees of the Cinemacon 2023, director Andy Muschietti and producer Barbara Muschietti revealed that a cameo appearance of Gustin's Barry Allen was considered for the film, but was left in the "cutting floor room" due to not fitting in the story despite Muschietti's admiration for what the Arrowverse show accomplished on its own. ==Reception==

Critical response Regarding Gustin's debut as Barry Allen in Arrow and the potential for a series, IGN's Jesse Schedeen stated his concern: "Gustin doesn't come across as leading man material. His awkward bumbling intertwining with Felicity's was cute, but rarely did I get the impression that this character could or should be given his own spinoff series." Schedeen eventually warmed up to the character, however, once the "dorkiness and social awkwardness" were downplayed a bit and the emphasis was placed on "his keen scientific mind". Grant Gustin as Barry Allen has received positive reviews by both fans and critics, with The Flash being the most watched show in The CW history. Since the premiere of The Flash, Gustin has been nominated for 20 awards for his role as Barry Allen and had won a total of 5 of them. In 2015, Gustin won the Teen Choice Award for "Breakout Star", in that same year he won the Saturn Award for "Breakthrough Performance" and was nominated for "Best Actor on Television". In the following year Gustin won the Teen Choice Awards for "Choice TV Actor: Sci-fi/Fantasy" and in 2017 and 2018 he took home the Teen Choice Awards for "Choice TV Actor: Action". Gustin's Barry Allen has been said to be the better Flash, compared to Ezra Miller who starred in the Warner Bros. Justice League. According to Nick Mangione from Geek.com, "By the time Ezra Miller made his brief cameo appearance in Batman v. Superman, we had already seen the perfect Barry Allen". He goes on to say "More than heart, more than a perfect embodiment of the character from the comics, Grant Gustin is the one true Barry Allen because his show allows him to be. At least at this point, the same can't be said for Miller and the DCEU." Kain, however, opined that the show has since gone downhill and that "Miller's Barry Allen is better in almost every way than Gustin's, though that's largely because he's not weighed down by CW melodrama."
