Also known as: レイモン(バーストモード), バーストモード, バーストモード(レイモン)
Reimon's black and red-colored form, introduced in Ultra Galaxy Mega Dai-Kaijuu Battle: Never Ending Odyssey.
In this form, Reimon becomes extremely powerful but violent in battle, as does Gomora, and will fight both friend and foe alike. Later in the series, however, he learns to evolve Gomora into Reionic Burst mode without entering Burst Mode himself.
