- Injustice 3 Flash speculation centers on which speedster joins Barry Allen on the roster.
- Kid Flash is widely considered the safest and most likely second speedster pick.
- XS, Barry's granddaughter from the future, is the sleeper pick if the story involves time travel.
- Reverse-Flash is effectively ruled out after appearing only as a premium skin in Injustice 2.
- Both prior games shipped with exactly one speedster, so a second Flash is overdue.
The Injustice 3 Flash Roster Question
The Injustice 3 Flash debate is one of the most persistent roster conversations in the fan community. Across both Injustice: Gods Among Us (2013) and Injustice 2 (2017), NetherRealm Studios included exactly one playable speedster: Barry Allen, the Flash. That choice worked fine the first time around, but by the second game many players were openly asking for a second runner — and they didn't get one.
Instead of adding Reverse-Flash (Eobard Thawne) as a full character in Injustice 2, NetherRealm shipped him as an alternate skin for Barry. That decision signaled something important: the studio sees Thawne as covered, not as a future standalone fighter. It frustrated a large chunk of the fanbase, but it also sharpened the question heading into the next installment — if we do get a second speedster in Injustice 3, who is it?
Video Highlights:
- Only one speedster (Barry Allen) has appeared in both Injustice games so far.
- Reverse-Flash was demoted to a skin in Injustice 2, making a standalone debut very unlikely.
- Kid Flash is the community's safest bet for a second speedster.
- XS is a dark-horse option if the Injustice 3 storyline leans into time travel.
Once you filter out the multiverse clutter — alternate-Earth Flashes, future Barry variants, and legacy speedsters with no mainstream recognition — the realistic candidate pool shrinks to just two or three names. The rest of this guide ranks those candidates, explains the reasoning behind each, and gives you a framework for predicting speedster roster moves the way roster analysts do.
NetherRealm's DLC patterns across Mortal Kombat and Injustice show the studio strongly favors characters with built-in fan recognition over deep-cut picks. Keep that filter in mind when evaluating any rumored addition.
Speedster Candidate Comparison
Every Flash-family character has been weighed against three criteria: mainstream popularity, gameplay differentiation potential, and story fit within the Injustice universe. Here is how the realistic candidates stack up.
| Candidate | Likelihood | Key Strength | Main Obstacle |
|---|---|---|---|
| Kid Flash (Wally West) | High | Fan-favorite status, strong comics legacy | Needs a distinct moveset from Barry |
| XS (Jenni Ognats) | Medium | Time-travel story synergy, TV show fanbase | Lower mainstream recognition |
| Reverse-Flash | Very Low | Iconic villain design | Already released as Injustice 2 skin |
| Future Flash | Low | Story potential | Confusing duplicate of Barry |
| Alternate-Earth Flashes | Very Low | Multiverse variety | Minimal fan demand |
The pattern is clear. The two credible contenders are Kid Flash and XS, and each makes sense for a different reason. Kid Flash rides decades of comic popularity and the affection carried over from animated appearances. XS benefits from an entire season of The Flash TV show built around her, plus a natural hook if Injustice 3's narrative involves the timeline — a reasonable assumption given how the previous games handled Superman's regime and dimensional consequences.
Fans wanted Eobard Thawne as a playable character in Injustice 2 and received him as a skin instead. Repeating that as a full character later would be an unusual reversal for NetherRealm, which is why most analysts treat a standalone Reverse-Flash as effectively off the table.
Why Kid Flash Leads the Pack
Wally West occupies a special place in DC history. For an entire generation of readers, he was the Flash — the sidekick who grew into the mantle. That dual identity gives NetherRealm everything they need for a distinct fighter:
- Youthful, acrobatic movement contrasting Barry's more grounded style
- A legacy-story hook that fits the regime-versus-resistance framing of Injustice
- Built-in audience from Young Justice and classic Teen Titans media
How NetherRealm Could Differentiate a Second Speedster
The biggest design challenge with any Flash addition is avoiding the "clone character" trap. Speedsters share the same core power fantasy, so a second runner has to carve out a unique combat identity. Based on how NetherRealm handled past similar-power characters, here is the likely differentiation approach.
| Design Element | Barry Allen (Existing) | Kid Flash (Predicted) | XS (Predicted) |
|---|---|---|---|
| Movement style | Linear speed dashes | Acrobatic, multi-direction rushes | Time-skipping teleports |
| Signature mechanic | Speed Force charge | Momentum-building combos | Timeline phase attacks |
| Character archetype | Veteran hero | Young legacy fighter | Time-displaced wildcard |
| Story role | Justice League anchor | Next-generation resistance | Future-warning messenger |
A Kid Flash moveset would likely emphasize momentum: strings that get faster and stronger as a combo extends, rewarding aggressive play. XS, by contrast, offers a genuinely fresh mechanic — treating speed as short-range time travel, with phasing, delayed-hit attacks, and afterimage setups. Both would feel distinct from Barry's established toolkit.
Even if a second Flash makes the cut, a third is extremely unlikely. NetherRealm rosters balance power fantasy variety, and stacking the Speed Force family too heavily would crowd out other DC corners fans are asking for.
Tracking Future Roster Reveals
Want to evaluate Flash rumors yourself as Injustice 3 news drops? Follow this verification process used by roster analysts.
Check the Source Tier
Only treat official NetherRealm or WB Games channels, plus major gaming outlets, as confirmation. Leaker lists and forum posts are speculation until corroborated.
Look for Pre-Reveal Marketing
NetherRealm typically teases characters with short trailer stingers. A lightning-heavy teaser segment is the strongest early signal of speedster involvement.
Watch the Skin List
If Kid Flash or XS appears as an alternate skin rather than a fighter, that mirrors the Reverse-Flash situation — a sign the character is considered covered, not upcoming.
Track Story Synopsis Details
Any mention of time travel, the future, or legacy heroes in official story descriptions strengthens the XS and Kid Flash cases considerably.
Fan demand moved the needle before — sustained Reverse-Flash requests in the Injustice 2 era proved the audience for a second speedster exists. That same energy now backs Kid Flash, which developers do notice.

Final Prediction and FAQ
Kid Flash - Most Likely
- Strongest fan demand
- Decades of comics legacy
- Natural legacy-hero story fit
XS - Dark Horse
- Time-travel story synergy
- Built-in TV audience
- Unique teleport-style moveset potential
Reverse-Flash - Ruled Out
- Already an Injustice 2 skin
- Repeating him would be redundant
- Fans have largely moved on
The final verdict: Kid Flash is the safest bet for a second speedster in Injustice 3, with XS as the creative wildcard if the story embraces time travel. Everyone else in the Flash family is either redundant, too obscure, or already represented through skins.
One speedster per game has been the pattern, but the demand curve and roster logic both point to change. If Injustice 3 adds exactly one new runner, expect it to wear yellow and red — or arrive from the future.
Q: Who is the most likely new speedster in Injustice 3?
Kid Flash (Wally West) is the strongest candidate. He is a long-standing fan favorite with deep comics legacy and animation exposure, making him the safest bet to join Barry Allen as the game's second speedster.
Q: Will Reverse-Flash be playable in Injustice 3?
Probably not. Reverse-Flash was added to Injustice 2 only as an alternate skin for Barry Allen, which strongly suggests NetherRealm considers the character already represented rather than a future standalone fighter.
Q: Why do fans think XS could appear in Injustice 3?
XS, Barry's granddaughter from the future, had a full story arc on The Flash TV show that built her a real fanbase. If the Injustice 3 storyline involves time travel, she offers both narrative relevance and a distinct time-phasing moveset.
Q: How many speedsters will Injustice 3 have?
Most predictions point to two at most: Barry Allen plus one addition. Three or more Flash-family characters would be unusual for a balanced NetherRealm roster, even with strong fan demand for speedsters.
