His life targeted by Black Rodimus, Hot Rodimus escapes
into the legendary cavern known as the Crystal Cave. Just as he
is cornered, the power of a crystal fountain spouting at his feet
changes him into a crystal-coated form, and limitless light flows
out from within him. Bathed in that light, Black Rodimus finds the
evil heart implanted within him by Megatron expunged, and he is
reborn as a heroic Cybertron warrior.
