Overview
First, let's look at an overview image of the two comic strip pages, with labels, just to appreciate how much there is to identify. Then we'll go through each section of the images in detail.
Details of first image
First, the Flashes that appear in real big, seen from the back.
- 0k: Johnny Quick from Earth 3? Goggles and goblin-shaped head don't match, but the hinged shoulders and general look is reminiscent of the guy.
- 0l: Speed Freak of Earth 47, from Animal Man #23 (1990). Spiky hair, yellow costume with diagonal red pattern, red lightning bolts "ears". Same as 4p.
- 0m: Flash of Earth 42, from The Multiversity #2 (2015)? Same as 4o, but from back here.
- 0n: Lia Nelson of Earth 9, from Tangent Comics: The Flash (1997). Blondie, purple outfit with a cape and a spikey symbol on the chest. Same as 4j, 4n.
- 0o:
- 0p: same as 4l, but profile view.
Next, the four characters at the center of the podium:
- 0q: Fastback, the reptilian rocket, of Earth 26, from Captain Carrot and his amazing Zoo Crew! #1 (1983) - thanks to RDFozz for pinpointing an earlier depiction of that one! Same as 6a, 7c

- 4k:
- 4l: There is a Mercury Flash (6x, 1g), but they don't look the same that at all...
- 4m:
- 4n: Lia Nelson (see 4j, 0n)
- 4o: Flash of Earth 42, from The Multiversity #2 (2015)? We only saw Steel, Batman and Wonder Woman from this Earth, but it's the same child-looking, chibi-style art... Same as 0m.
Let's take a detailed look at the bottom left podium on the big panel
There are some characters here that appear as just part of an outline with no details, and are probably impossible to identify (but if you can identify them, do add the answer). These get the labels 5a–m, which don't appear in the overview image.
- 0e:
- 0f:
- 0g:
- 0h:
- 0i:
- 0j:
- 1a: Same as 4f?
- 1b: Danica Williams of Earth 12, from Batman Beyond Unlimited (2010), same as 4g.
- 1c: Accelerator of Earth 39; see 4c, 6u.
- 1d:
- 1e:
- 1f: Probably Bizarro Flash of Earth 29, from All Star Superman (2007), same as 4i, 6w.
- 1g: Mercury Flash of Earth 44, the same as 6x.
- 1h:
- 1i: Red Racer of Earth 36, from The Multiversity Guidebook (2015). Same as 6y.
Now the few characters on the top left
- 0a: Blitzen of Earth 10, from The Multiversity: Mastermen (2015)? Nazi-looking helmet fits, but not the blue pants or the "ruffed" boots and gloves...
- 0b: Unnamed Flash of Earth 30, from The Multiversity Guidebook (2015). Suit is red on the front, black on the back, kneepads, yellow boots with straps, yellow gloves, bike-like helmet

The right part of the bottom podium on the top right
- 2k: Flash of Earth 22, from Kingdom come (1995). Same as 4b.
- 2l:
- 2m:
- 2n: Jace, the Flash of the Planet Petrus, post 2754 A.D, which appeared in Speed Force #1, 1997. His father was the Flash before him & he saved his son (Jace) from dying from a disease by trying to take him in to the speed force, but failed. The Speedforce took him instead & passed his speed on to Jace. It's the fathers costume, but it appears to be on Jace (who is blonde, while his father wasn't).
- 2o:
- 2p:
- 2q:
- 2r: Aquaflash of Earth 32, from The Multiversity Guidebook (2015). No explanation needed. Scales!
- 2s:
- 2t:
- 2u: Blood Flash of Earth 43, from The Multiversity Guidebook (2015)? The picture's pretty blurry but this guy's mouth seems odd. Earth 43 is populated by vampires, including a vampire Flash
- 2v: Mary Maxwell of Earth 6, from Just Imagine Stan Lee with Kevin Maguire creating the Flash (2001). White suit, knee pads, ribbon-like headdress
- 2w: this purple/white costume is a bit reminiscent of Marvel's speedster Quicksilver in the 2018 Quicksilver: No Surrender series (picture)
- 2x:
- 2y:
Finally the top podium on the top right
- 3a:
- 3b:
- 3c: This costume is reminiscent of Robin's old one back in the 50s-60s?

- 3i:
- 3j:
