 The run starts by introducing two main antagonists , an aging politician , who is using a strange portal to enter other people 's minds and commit crimes , and Mako , a <unk> <unk> who <unk> other <unk> in order to obtain their power . Constantine 's attempt to play them off one another only succeeds in making them join forces in a further plot . Constantine then traps them both with considerable ease , and questions how this has been so easy . It then becomes apparent that he has been manipulated by the ' Golden Child ' , his twin who did not survive childbirth , and has been manipulating events for the whole of the series , including his battle with cancer and many other events . He declines his twin 's offer to merge souls , suspicious that his twin has been weakening his will in past years to make him accept this offer , choosing instead to take control of his own destiny .
