actually it would be like this:
Prime-Good
Kong-Bad
P+K= Primal Kong-Bad
THEORY: Stripped of the Matrix, Prime's mind fights against Kong's can he conquer his primal urges and return to being the heroic leader he was or is it to late, has the darkness he has hidden for so long finally taken over, one question remains will Kongs primal fury take over or can the wisdom of ages prevail and light our darkest hour? one thing is certain Primal Kong will do anything to get to the top even at the cost of his loved ones.
Megatron-Bad
Godzilla-Good
M+G= Gojira Prime-GOOD
THEORY: Megatron's darkness is consuled by the ancient wisdom and beauty of nature as he adapts to the Matrix and his new form as Earth's mightiest warrior Gojira Prime, now with new purpose and the strength of many gods he and the Decepticons have adopted the Earth as their home, woe be those who threaten their new home. With new found compassion Megatron will perserve all life no matter what even if it kills him.
