Striking Power

In terms of striking power, there are intriguing differences between the two speedsters. Director Zack Snyder mentioned that in The Flash’s fight with Superman, the Flash could theoretically punch at the speed of light, although he refrained from doing so. While this statement isn’t backed by an actual feat, it adds an intriguing dimension to the Flash’s potential striking power. On the other hand, Grant Gustin’s Flash displayed impressive striking power when he destroyed Devoe’s satellite in Season 4. While Grant’s Flash showcased a remarkable feat, Ezra Miller’s Flash potentially possesses unmatched striking power, assuming he can tap into the speed of light as mentioned by the director.

Fighting Prowess

When it comes to hand-to-hand combat skill, Grant Gustin’s Barry Allen likely holds an advantage. With years of experience as the Flash and numerous encounters with formidable foes, Grant’s Flash has honed his fighting prowess. Conversely, Ezra Miller’s Flash is portrayed as relatively inexperienced in the DCEU, which suggests that his hand-to-hand combat skills may be less refined. Thus, in terms of fighting prowess, Grant Gustin’s Flash has the upper hand.


In this comparison between Ezra Miller’s Flash and Grant Gustin’s Flash, both speedsters showcase remarkable abilities and strengths. Grant Gustin’s Barry Allen possesses exceptional travel speed, combat/reaction speed, durability, and fighting prowess. Meanwhile, Ezra Miller’s Barry Allen exhibits potential for immense speed and striking power, although he still has room to grow and gain experience. Ultimately, while Grant Gustin’s Flash dominates in several categories, Ezra Miller’s Flash offers an intriguing potential that could develop further in future DCEU appearances.
