Even so, Amazo only works if we apply a no-limits fallacy and assume his duping ability was entirely unbounded... Because Freeza was WAY more powerful than anyone/thing we saw him dupe. Especially if we start talking about his higher transformations. /shrug
...Though I suppose Amazo *could* BFR Freeza to another dimension, like he did to Oa. Don't think Freeza has any way to counter that.
There is really nobody that could ever stand up to Frieza in the DCAU. Amazo is the only one who could possibly do it, but other than him it's not even close.
Frickin Nappa has more destructive power than the laser beam that KO'ed Superman, and that wasn't even a direct hit, it just glanced him and he was KO'ed lol. I'm talking about the JLU watchtower beam.
