Teaser pic! Dawn will be making her debut in an upcoming story (and will cameo before that). And because I'm anal like that sometimes, the plates she's using for squats are properly labeled at 150 pounds (68 kg) each...which is what a standard Olympic-size plate of that size would weigh if it was made of an osmium-iridium alloy. So she's lifting for a workout, not counting the obviously ridiculously strong bar, 3000 pounds (1,361 kg).
Yes, I think too much about these things sometime. Also, at current prices in the real world, the weights she's lifting would be worth roughly $22.4 million dollars. Obviously someone has a much better supply of osmium and iridium in her universe.
