Made at the request of STPrime, these are a set of accessories meant to go along with my previous item, the Siege Ultra Magnus Thigh Extenders, that wrap around Magnus' existing leg and the extender, and give his legs the details that the G1 Ultra Magnus toy had. They also add extra detail to the vehicle mode via a small ladder, and gas tanks, which feature an additional 5mm port to attach weapons or other 5mm accessories. These plug into the "breather holes" on the sides of his thighs, meaning they also help stabilize the connection between Magnus' original leg and the thigh extender, however getting a proper fit will be slightly different on each figure, so you may need to do some trimming and/or filing/sanding down on the interior pegs until these fit on your figure just right. Lastly, with this version, Ultra Magnus CANNOT TRANSFORM. There is simply not enough space between his lower torso and the top of his leg in vehicle form, so this version of the thigh accessory must be removed to transform your figure.
For those who are ok with a portion of the thighs being exposed, and want to still be able to transform your figure with this item attached, a Transforming version is available here:
