User blog comment:Radionatix/Who is the most powerful Godzilla villain (This time I want the real answer)/@comment-25285745-20160216161346

Another thing to consider is how powerful the villain kaiju was in relation to the Godzilla it faced. Going by that statistic, the list would probably consist of Keizer Ghidorah, Destoroyah, Hedorah, Super MechaGodzilla, and SpaceGodzilla.
