Lego X-Men Sentinel - scale from the animated series
This Lego X-Men Sentinel design is based on their appearance in the 90's animated series. Here is a comparison between the official Lego X-Men Sentinel set 76022 and my model, to show you how the scale is a bit better fit for the massive threat they are in the animated series.
I replaced the official Lego minifigs from the set with the ones I made based on the animated series from the 90's. Only Magneto remains unchanged.
