Alex and Rambo were at a valley which was also a training field, rampo tells alex that he will be teaching him how to control and suppress energy. Alex says that he doesn't really need to learn how to suppress his energy and rampo tells him that learning how to suppress the energy he releases is very important, he tells alex that he has a very massive and destructive amount of energy in his body. Alex says he knows he has a very high energy levdl and rambo tells him he isn't talking about that, he explains to alex that he has two types of energy. He explains to him that he has his normal green energy which is very massive and another one called demonic energy which activates when he is in a state of danger. Rambo explains to alex that once his energy level is low or when he is in the face of death or even enraged, his demonic energy activates immediately. Alex asks rambo if this demonic energy is black by chance, rambo then tells alex that he is almost entering puberty stage so his demonic energy is bound to awaken each time he experiences rage. Rambo then asks alex if he can recall the amount of times he has used his demonic energy and alex tells him he used it against Kirihai once, he also says he remembers going insane when he fought a giant scorpion in the forest of death. Rambo sighs and tells alex that he needs to learn how to control that power, rambo tells alex to take his shirt off and alex asks why he needs to do so. Rambo then tells alex to stop being stubborn and do what he says and alex pulls his shirt off, rambo then recites some incarnations and then touches alex on his chest and then a black magic circle appears on alex chest. Alex looks amazed and ask Rambo how he managed to do that and Rambo tells him that the mark on his chest gives him the ability to release as much demonic energy as he can possibly can, alex then ask rambo what will happen if he goes out of control and Rambo explains to him that he is only 12 years old so in that case he won't be able to release much. He tells alex that there is only a certain amount of demonic power he can release at his age, he asks alex if he is ready and alex says that he doesn't feel too good about this but he will be fine. Rambo tells alex to try his best to release as much as possible and then suppress it and then before he knew it, dark energy started to flow over alex body. Alex's then begins to groan in pain while he starts to transform, rambo tells him to calm down and suppress his demonic energy and then the energy flowing in his body increases with an even more incredible power. The black demonic energy flowing over his body was so powerful that it began to blow the trees, alex finger nails starts to become sharp along side with his teeth. He then begins to grow wings and then black Mark's start to appear all over his body and then he releases a powerful roar which was strong enough to make the entire valley shake, rambo seeing this is shocked and says to himself that alex has managed to enter stage one of his demonic transformation. Alex then roars and starts to shoot fire balls at rapid speed, rambo then summons his sword and starts to counter all of alex fire balls. As he was doing so,alex jumps out of nowhere and tries to attack Rambo but Rambo quickly jumps out of the way to dodge alex making alex destroy the ground and created a huge hole. Alex then shape shift his hands to sharp edges and then stretches it out to attack rambo, rambo then says that it was a bad idea to have thought alex will be strong enough to control his demonic power. As alex begins to throw attacks at rambo, he prepares a gaint fire ball and then flash steps behind Rambo ready to attack him with it . Immediately rambo realizes this, alex is already behind him and then blast the massive fire ball at rambo which was so strong that he blasted him throw 5 hills, rambo is then lying on the ground injured with some burn on his body and then alex flies over to him.

Rambo then tells alex that it was about time he came back to his senses and then as alex was struggling he roars in anger while trying to break free from Rambo's sealing technique, rambo then uses some hand signs and then a giant magic circle appears below alex and then a giant beam just blast out of it while alex was in the middle of it making him to roar In pain. As he was being hit by the giant beam of light, he start to turn back to his human form and then and then after he turns back to normal, Rambo's magic circle closes up.
