Bipedal
From Medapedia
Bipedal or also known as Two-Legged (二脚 nikyaku) is an average and well-balanced leg type. This is the leg type players always start out with in the beginning, as the legs from all Medabots of the KBT and KWG series are of this type. This leg type is the most abundant leg type. They battle best in grassy areas, good in rough and urban areas and poor in barrens and water.
