>>89703813>>89703851Starfire's abilities vary from writer to writer, and she fluctuates a lot in the cartoon, but generally speaking she's the Superman of the team.
She has 100+ ton strength, the ability to fly at relativistic speeds, and the durability to survive being punched by her equally strong sister.
Consider: Primarchs are considered among the toppest of top tier 40K fighters. The greatest feat of strength shown by them is by Magnus, while pumped up on a massive amount of psyker powers, throwing one of Russ' tank-sized wolves over his shoulder. Those things are roughly the size of Sherman, so around 35-45 tons.
There is some really powerful stuff in 40K, but most things can't hold a candle to cosmis superheroes, simply because they often combine incredible speed with incredible strength. There are very few things in 40K that can fight a supersonic opponent, let alone one that can almost hit lightspeed. Starfire is totally vulnerable to psykershit though.
