Whenever Iris turned a speedster in season 4, event 16, „operated Iris, Run,“ she was given a definite costume outfit from The Flash — in addition to a new color.
When Iris West-Allen (Candice Patton) gotten Barry Allen’s (give Gustin) forces in Flash period 4, episode 16, „operate, Iris, operate,“ she was presented with a distinct search from the lady spouse — such as her own unique purple super results. The key reason why Iris had been stylized thus in another way from the girl spouse and disguised character, referred to as „The Flash,“ had been never fully discovered in-universe; however, there are plenty of lover theories as to why — and a narrative reason that renders total good sense as an aesthetic behind-the-scenes choice.
The Flash is the 2nd show in CW’s Arrowverse, which began with Arrow in 2012.
The Flash employs the activities of a forensic scientist which grows superhuman increase abilities after a fresh particle accelerator explodes. According to the figure from DC Comics, The Flash shows a determination to divert from its origin materials, and explore basic ideas within the own means — like the nature of Barry’s speeds, exactly how superspeed and opportunity vacation perform, and the idea of the „increase power.“
The majority of fan ideas with regards to eye’s purple lightning point out Iris’s commitment together with the performance power, because this is among the most evident difference in their and Barry. The precise technology behind the real difference is never researched completely in The Flash, mostly because eye opted not to carry on creating meta-human powers towards the end of this episode. Narratively speaking, however, Iris’s unique purple lightning was conscious preference: it absolutely was completed to touch in the identification from the „mystery girl“ viewed before in season.
The Reason Why The Flash Gave Eye Imperial Lightning
In a job interview with TV Tips Guide, manager manufacturer Todd Helbing affirmed the costume option and super colors useful for iris-in „operate, Iris, Run“ were designed for „a certain factor,“ alluding to a big unveil after the season. Needless to say, the growing season 4 finale included a long-awaited response to who the strange feminine speedster had been whom held appearing throughout the season. Initial displaying inside the Crisis on Earth-X crossover, the lady exhibited common comprehension of employees Flash, along with speedster capabilities — characterized by purple and yellowish super. The finale affirmed just what fans had already thought in line with the clues: she got Barry and eye’s child from the 
future, Nora West-Allen. Eye’s purple lightning in event 16 was thus a means for the tv series’s imaginative professionals to touch a link between Eye plus the secret woman.
Exactly What Eye’s Purple Lightning Implies From Inside The Flash
In-universe, the cause of eye’s lightning shade is less obvious. While Iris’s purple super is never discussed at length, the different color likely keeps something you should would with her union because of the Speed Force. The performance Force was a mysterious sentient entity that is present outside of the multiverse and supplies speedsters and their know-how. Whilst it can reveal alone into an actual physical type to speak, mainly, it is available as an extra-dimensional room. Barry enjoys went to the accelerate power on numerous occasions on tv show, and happened to be trapped around for some time in an event comparable to the Christian notion of purgatory. For the Flash, speedsters like Barry and Iris’s bro Wally western (Keiynan Lonsdale), who passes by „Kid Flash,“ reached her connection to the speeds power in a similar manner, and so both generate yellow lightning while they operate. Different speedsters within the collection, however, generate an alternate colored lightning — like Iris’s purple variation.
Since eye and Wally are siblings, it seems unlikely that family genes are reason for Iris’s distinct lightning tone; therefore, their different relations making use of speeds power is a very most likely reason. Although the different lightning might have to do with the lady sex, this wouldn’t describe the reason why the Flash’s daughter Nora enjoys purple and yellowish lightning. Both Wally and Barry got their particular meta-human powers considering any sort of accident that put them in a coma. Iris, conversely, gotten the girl powers whenever a meta-human transferred Barry’s forces to her. In such a way, Iris’s superhuman rate simply awarded to their fully-formed, versus being developed, as it’s in other speedsters. The Flash already set up that speedsters which obtain their particular skills through the use of medications, or by way of the unfavorable performance Force, generate bluish and red super respectively, so that it is practical for Iris’s super to possess a similarly specific tone.
