Thundercore is the bigger version of the Xtractor Drilladome. Of course mobility was sacrificed for raw digging power: the Thundercore is the strongest Xtractor when it comes to penetrating the Invizimals soil and extracting its precious energy. If you use this Xtractor in combat, make sure it's partnered with a pure offensive one, like Slammer.
