Mighty Griptians are stronger than the standard Griptians. These creatures eventually replace all of the weaker variants later in the game, suggesting Mighty Griptians are Griptians that have matured and/or reached an advanced stage of their lives. They are slightly darker in color, and are more fearsome and dangerous; they have grown spikes along their backs (increasing the damage of their roll attack) and a set of wing-like protrusions from their shells. In some instances they can be seen hovering above the ground as they are rolling, but only for a short moment. These Griptians are summoned by MB in the Bioweapon Research Center, and Mighty Griptians also attack Samus during the post credits.
