The Battle Droid, first shown 10 years ago in Episode I, has always been a challenge for toy designers. George Lucas was none too kind to the action figure crowd by insisting on an ultra-thin robot design that in the film enjoys massive range of motion and transforms. Almost every aspect of the Battle Droid design has proven difficult to translate into toys, starting with the head and neck joints, going all the way down to the feet.
Arms suffer limited articulation, just a simple hinge elbow if anything, and only with the Clone Wars line has Hasbro tried ball-jointed shoulders. Poses involving holding the blaster are either limited to straight-armed inaccuracies, or require preposed arm sculpts which lose their looks when posed in other angles. However, many collectors continue to ask: what's a Battle Droid when it can't even hold its weapon properly?
But nothing has crippled Battle Droid figures like their slim leg designs. Once Lucasfilm insisted on a more accurate design, the leg designs got too thin to employ knee articulation, and Hasbro feared that the parts are so thin that a harder plastic would easily break and cause danger to small children. This has led to the notorious bendy-legged Battle Droid figures which cannot stand on their own. Their small feet, narrow stances, and top-heavy bodies simply cannot stand on their own for very long no matter which figure is involved.
Hasbro has shown with their Super Battle Droid figure that they are willing to beef up droid limbs a little in the service of adding articulation, yet that figure's lack of articulated ankles ultimately suffered the same bending problems as the other Battle Droids and Super Battle Droids.
There may need to be significant thickening of the arms and legs to get us to a point where there's enough articulation to keep the figure upright and allowed to pose in a multitude of ways.
So the question becomes: how much beefing-up of the limbs are fans willing to endure to get a Battle Droid that does what fans want?
