User blog comment:Legionwrex/Reaper vs thresher maw, who would win/@comment-3315329-20110414042959

Reaper at range, obviously. But at close range? I'd say the Thresher maw actually. They're massive, evasive and what if it got inside of the Reaper? We know what Shepard can do to a Reaper's insides, no doubt a Thresher maw could do the same.

But it's all speculation with untold variables.
