>>10661952McFarlane's Halo aliens are 1:16-1:17 scale, so they'er not even close to being in scale with a Mafex figure.
And you can find them for half way cheap, around $20-40 if you're getting them used and maybe missing an accessory or two.
Humans in pic are 4" to give you an idea of how big the aliens are. Brute in the back is like 5.5"
