I'd need instances specifically but I recall him doing this to shave
It was posted before in this thread by sb else so didn't feel the need for repost
That's not a criteria I believe
His powers come from the Sun's light, so wouldn't it make sense for Heat Vision to have similiar his powersource?
This would definitely be good for Luminous if he fits the criteria himself (especially since this is a relatively inexperienced Supes yes?)
Inexpirienced(Episode 24 of his own show named Solar Power)+depowered(In the beginning of the episode he was s
o weakened that he could barely move a big rock & his heat vision became harmless thanks to Red Sun Radiation. Just before fighting Luminous for the last time[where the laser feat takes place] Professor Hamilton said Superman was almost powerless.), so slowwer than usual. There's also the fact that Luminios isn't that relavent of a villain, when he has only 2 epsiode as a main villain pretty early on & the rest are just cameos. Also he used to work for Lexcorp, so maybe Luthor's tech could scale to his.
Sparkles can mean "a glittering flash of light" & Stargirl appeared in the Justice League Unilimited Era where LS isn't that rare. Also Supergirl has a feat of intercepting her beam & she has reacted to Livewire aswell.
This would be hyperbolic but the consistency is there I guess so we could argue it
Superman casually
intercepted cloud to ground lightning yet sometimes Supes has trouble dodging her attacks & unlike with Luminous, Superman wasn't depowered in those cases. Also her claim came from her second appearance, Double Dose. Between her debut episode & this episode; people have been researching her powers, so her words aren't really that baseless.
Mostly because you;d need to go case by case but there certainly is evidence for it I think
The Sinestro statement is already mentioned in their pages & used for scaling. Grean Lanterns, Star Saphhire & Sinestro's powers work the same, they have beam clashes with each other & dodged each others attacks(proving they have the same speed), they have been reflected by metalic object like WW's braccelets(which have shown to
conduct electricity & heat before just like real metal) & Hawkgirl's mace(the profile metions they have been reflected by mirrors too but i don't remember when). The Manhunters were made by the people who created the GL Corp for a simular porpuse & had a beam clash with GL like i showed in my other comment. Superman has dodged rays from them & is generally protryed as above. What proof do we need more?
