I can't believe how many childhood memories of Bionicle this brings back. Those were the days…..

Mata-Nui/"Matoran Universe robot" standing is as tall as the diameter of the Earth (12.000 km), meanwhile ,as far as I have seen in trailers and etc, a reaper could be about 1 km more or less. So, either those are some giantass reapers or a tiny Mata-nui (even the prototipe robot is bigger)

On a more related note, and despite the point stated above, this image is great and you should feel great.
