I suppose.
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. mmm
