Listen up you highly unintelligent person.- Both Raven and Superboy could give Polaris and Rachel a run for their money and/or take the majority. Bart Allen could probably take out most of the x-men or imperial guard on his own. Wally West also appeared later on in the battle with Light... Smasher is shit, get real.
- What defeats he has doesn't matter really....Surtur has very few victories, and he would still one-shot Vulcan...Your quantity of victories or losses matter nothing, only the quality of opponent's you've faced.
The lineup he faced consisted of:
Raven, Wondergirl, Tim Drake, Bart Allen, Cyborg, Red Star, Superboy, Tempest, Argent, Vox, Captain Marvel Jr. Hawk and Dove, Speedy, Green Arrow, Ravager, Wally West, Wildebeest, Bumblebee, Flamebird, Damage, Beast Boy and Pantha.
Wally West appeared later however, I don't think he was among those who battled him.
If you had read the comic, you would've known that Dr.Light was not trying to kill a single one of them but to prove a point. He had all of them beaten and helpless, but decided to pull Speedy and show her to Green Arrow. If Arthur wanted them to die, they would already be dead.
His previous losses are not accounted for because Zatanna had lobotomized him via magic.
- Dr. Light was actually able to affect Superman. He was only temporarily blasted away/knocked down, but his blasts had an effect...
