I have very little information about this line, if in fact it is a line. There are, however, several parts that appear to be cast in colors that I haven't seen anywhere else which leads me to believe that they are not customs or kit-bashes. All of the figures appear to have the extra chest armor pieces, like the originals and the Trendmasters-manufacturered lines.
I found them on @bajai.market's Instagram feed where it looks like they were sold in January of 2018. I have reached out to see if @bajai.market has any additional information about them and will update this page when I hear back.
Green and Red Mars-Bit
Black and Green Saturn-Bit
A version of Saturn-Bit with green radar dish mounts, Mercury-Bit's legs and red and white Thunder Arm weapons. The weapons were the first thing that made me think that this was a distinct line as I have never seen them molded in this color scheme before.
Blue and White Mercury-Bit
This version of Mercury-Bit includes blue shoulders and feet, a white head and green accent parts. @bajai.market's example even has several decals applied which implies that this could be the second knock-off line that included stickers.
Red and Green Jupiter-Bit
