Mii

Mii, a spirit of flowers, fertility, and reproduction. Her gigantic breasts are said to represent and contain Earth's life-giving energy. In addition, her already humongous breasts grow larger yet as Mii increases in maternal strength. Mii can also enlarge her whole body to giant size when needed. Mii's other powers include temporarily increasing her breast size, making her entire body grow, reflecting projectiles off her chest or absorbing them into her cleavage and extreme muscular strength needed to carry her absolutely enormous breasts around without hurting her back or tipping over forward.
