That's a description of small general details. Tank Leg Parts are big and bulky, usually with treads of some sort. The "stubby legs" aspect comes from Totalizer, who has six caterpillar-like legs for slow mobility.

There is no "Boat" type; only "Sea", which takes on the appearance of marine animal lower bodies or (in the case of a hypothetical Medachange) seafaring ships.

"Wheel" can be two legs with noticeable wheels being a feature (example, Stingray: the wheels make up his heels and the back half of his lower legs), or they can have four wheels and a blocky lower body. Multi-leg looks like a centaur, an insect (like a scorpion), or spider/octopus-like.

Are there some general similarities? Yes. That's unavoidable. The difference between these Leg Parts and your concept is that there are specific, prominent differences in both appearance and operation.

To bring up your Pokémon analogy; the difference is that while Pokémon has added such types, Medabots has NOT. Attack attributes and skills have been added and removed on occasion, but the seven available Leg Types have always been consistent.

Your Reverse parts would have minimal difference in appearance and mobility to Two-legged Parts; that's my issue. Plus, if I allowed this then I would have to allow anyone to make weapons and Leg types as they please. The problem with that is that there's enough Medabot content as-is. I don't wanna force RPers to have to take in more info and discern fact from fanon.

In addition, since the Leg type would be fan-made, only your Medabot model would have that Leg type, giving you an uneven edge. Unless you created a crap-ton of Medabot models with specific actions, skills, and attributes, that would not allow a great deal of variety.

And finally, reverse leg joints have already been categorized as two-legged ala Blackram.
