In Justice League: Crisis on Infinite Earth’s Part 2 and 3, we are introduced to yet another animated counterpart of the character Dr. Light. As the name implies this character has the ability to manipulate light, and often shoots out light beams. This thread will justify why Doctor lights beams should be accepted as light speed as well as how the proposed scaling will affect the verses.

LIGHT-SPEED REQUIRMENTS
According to the Laser/Light Beam Dodging Featsguidelines, a fictional beam can be considered light-speed if it meets several of the following:

  • Reflects, refracts, or scatters like real light.
  • Is explicitly described as light-speed.
  • Is composed of photons or referred to as “light.”
  • Originates from a realistic light source (e.g., sunlight, camera flash).
Beams that behave unrealistically—curve in open air, interact physically, or appear solid—are disqualified. However, strong adherence to realistic light behavior may still qualify a beam as light-speed in the absence of red flags.

Dr. Lights beams:
1. Travel in a straight line
2. Refracts/Reflects off solid material

3. Explicitly stated to be light based by reliable sources multiple times. 2. 3.
In the movie, lights based attacks are the only thing that the anti-monitor and his shadow demons are vulnerable to so Dr. light is a key fighter in the battle, with lex ultimately creating a plan to beat the anti monitor by harnessing sunlight, once again proving that Dr. light manipulates real light.
4. It causes explosions through rapid vaporization that leaves smoke-like a pour and scorch marks on the ground.



The comic lore of Dr. Light reinforces the idea that she’s manipulating actual photons like the name implies, rather than some arbitrary form of energy that causes bright flashes, with his beams being explicitly stated light-speed in other source material.


As the clips above show, John Stewart is able to react to her light beams. Much thanks to @Ozcantabak for the calc, which gives around 1.1c speed. which essentially scales to almost all super powered beings in the JL.


This scales to the DCAMU because John Stewart fights the same Constantine from the DCAMU, instead of a rebooted version as his punishment for creating the multiverse by killing darkseid before he could invade the earth, he was cursed to wonder around the multiverse without any memories, with Constantine capable of easily reacting to John Stewart. It is essentially the same as post-crisis and Rebirth superman being the same being.

This John Constantine should be weaker than his DCAMU prime with him stating things like “still enough juice to pull off a clean up spell” implying he’s no where near his peak after all those years of wondering and becoming an old man, or him saying “i’ve just remembered my name, my bag of tricks is not quite up to this”, all pointing to the fact that he was more capable at his peak during the DCAMU.

In conclusion,
1. Dr. Lights beams are REAL light beams.
2. John Stewart Reacts to them to give an FTL rating (~1.1c), so all the heroes who scale to John Stewart, are also FTL.
3. John Stewart fights a far less capable DCAMU Constantine, who keeps up with his speed, so all the heroes who scale to Constantine in the DCAMU, are also at least FTL.

Looks alright. iIRC it's also arguable that Kryptonian Heat Vision in the Tomorrowverse is light-based, which could add some more supporting feats to this.
yes it can. We will probably tackle those after. but i lowkey think the tomorrowverse and dcamu verse should actually be fused into one, while still having separate profiles since we know for a fact it’s a continuation.
 
My main issue is if 6c combat speed for everyone works, especially since the DCAMU would allow Batman-tier people to scale to the feat.

The calc itself my main issue is that it looks like you're having GL's arm move far much. But the constructs earlier in the video can form when the beams fire, so the construction speed is at least of comparable speed.

Dalesean recalced it to 1.1c

yeah we’re using dalesean’s calc. his arm moving 90 degrees isn’t far much at all, that’s literally what he does and dalesean agrees.



idk how else u would describe this movement but a 90 degree turn

We also blatantly have this issue of batman reacting to these ftl beings in every medium (comics, dceu, games, etc) where a large dc universe is at play. it’s either chalked up to outliers for batman or he just scales. this should never really be an anti-feat.

Using Batman as an anti-feat seems wack since:
It wasn't so much Batman, as Constantine fight a bunch of people that would themselves crossscale across the franchise. If Constantine is FTL then most superheroes and villains would need to be upgraded as well under that logic.

What’s the problem with this? he literally has magic powers, and is consistently on power with meta humans speed wise.
 
There isn't, it just means we'd have to upgrade everyone to FTL as well because of the amount of crossover fighting there is.
Not really ngl, after going through the profiles again, Constantine is really the only one who’s getting elevated to this tier. Zatanna, Etrigen, etc, were already in that metahuman tier.

Anyway, you’re the last vote we’re waiting on, so do u agree?
