Bioroids are not restricted to humanoid forms. Here is the Scout class Bioroid and the Heavy class Bioroid. Oddly enough, they look similar to the Geth from Mass Effect.
About this creation
The H Type is built using the same frame as the R Type, but uses heavy joints and armor, increasing strength and durability but reducing agility and speed. The H Type can deploy weapons too heavy for R Type bioroids, making them comparable to juggernauts.
Note the increased chest armor to more significantly protect vital functions, such as the power core. The arms have been redesigned for enhanced strength and range of motion.
The H Type replaces the back mounted weapons rack for dual thrust jumpjets, giving the H Type limited aerial capability.
S Type seen here with R Type for comparison. I remade the K9000 from the space police sets to be a bioroid. A quadpedal scout unit that's quick on its feet, and has a reduced profile, making it much harder to spot and hit.
Another comparision to the K9000 model and the S Type Bioroid. Equipped lightly for speed, the S Type is equipped with two drum-fed LMGs.
Posed next to a soldier for scale. The LMGs are removeable for use by human infantry.
Nice use of the K9 space police pieces. I used some of the same for my Katana and Ninjato. If you have a minute, check them out, I think you'll like them. I also have a few hardsuits and robots you might like.
