History
Awoken Too Soon

According to Professor Pickle, Dark Gaia had a history of causing the planet to break up into fragments, not unlike the situation that resulted during shattered world crisis. Tikal indicated that the breaking of the planet following the Super Genesis Wave was an acceleration of the natural cycle, happening prior to its proper time. As a result, Light Gaia was left weakened and unprepared for the task that lay ahead of it. Additionally, portions of the creature's energy began seeping through the cracks in the planet, and some coalesced into Dark Gaia's Minions. (StH: #259, SU: #63).
