K4 (Short for H0M1K4) was an old Hand Of Artahka robot and the prototype of what is now know as the Maxilos robots. When the HoA disbanded, K4 was left abandoned in a laboratory in Ze-Nui, the island which represented the GSR’s left foot. When Turaga Kikag and a small group of Matoran discovered and entered the lab, K4 was activated for the first time in centuries for security measures. After first meeting the Turaga, K4 began developing sentience.
I know most self-moc’s tend to go through varying levels such as matoran, toa, turaga and titan. Though its alright if you don’t want to do variants, just would be interesting to see you attempt it :3
I think this is quite decent. The silver Piraka shins are a bit bland and detract from the moc, but the rest is pretty ok. The inclusion of system only on the back of the hands is also a bit strange, so I would recommend throwing a bit more system scattered throughout the moc to make it seem more in place.
They’re not intended to be horns, but rather head ornament things. While I agree with the head ornament things (not actual name for them) being odd, I actually like it.
