It first appeared in the (3).
Denma thinks if he take one Pentagon out, the rest 4 will also surface. He will get them one at a time.
Their symbol is a star and a number in it. Gaal is 3.
Equivalent Mass Substitution will hit jackpot if it gets developed. This is exactly the power that they chased after day and night.
When Gaal was on planet Urano. Pentagon was currently in the hyper-acceleration chamber for a hyper-speed train. In here, the passing train creates a sudden drop in air pressure and sucks everything nearby.
Denma Introduces that he's Dike and he says, he may be trapped in a child's body for the time being, but he'll never forget that Gaal sold Guyrin over to El through the slave market. Then Gaal says that they didn't take Dike's girl, he mean, lady. She came to them and he don't know why, but she asked them to sell herself to El through the slave market. He said that he can speak to Dike because Pentagons have been disbanded. Then they suspected for her ulterior motive, but they had to take her offer because they were running short on cash. And then Dike can find the related records in the Pentagon files he've handed over to Dike.
In (15) and 14. A.E. (3), Denma gets permission to get Yahwah to catching them. Yahwah listens to Denma's word. And Yahwah asks Uriel to pull any information on them. Uriel shows last year's scouting list. They're 3 of the 5 are Quanx, and they're all wearing masks. Because they didn't want each other to know who they're, so they may be on the same side but they haven't seen each other's face. And Uriel says got one last year, and another one recently, but didn't get their leader, Eldgon, yet. Then Uriel shows the 2 she has captured. Yahwah is surprises to see their faces. Edrei says to Jet that Dr. Yahwah withdrew his punishments. And Edrei tells Denma got Yahwah's permission to take revenge on some Savoys, and he said that they sold Denma's girlfriend to a slave market or something so they happened to catch one of them this time and Denma said he'll use him as a bait to get the other 4. Then he tells the name of their group is Pentagon. At this point, Jet makes a meaningful look.
Jet thinks the 2 members of Pentagon that aren't Quanx, it seems like the guy who Dike captured is Gaal, the cool guy of Carlburn. Then Jet thinks this is exactly why he told that old man they keep every member strictly Quanx, and he wonder how much that big-mouth blabbered on to Dike. Jet angry so he breaks the cup. And Jet thinks even the Quanx members don't know each other, so Gaal can't say anything about them. Jet thinks they could temporarily work as a team because they all had that one thing in common, the secret that they all had to keep from anyone around them, for their own protection, all 3 of them are Hyper-Quanx, with 2 or more powers. Jet uses restoration Quanx ability to restores the cup, and Golden hair uses enhanced strength to pulls out the necks of Ballack and his green friends.
Yahwah says to the golden hair, Eunguy that Randolph, Eunguy's Pentagon codename certainly suits him better than Eunguy. Yahwah threatens others to reveal that he was Savoy. And Yahwah says one of those 2,500 Quanx also used to be one of him Pentagons, he takes it he 2 aren't friends anymore.
Jet enters his room, but there's Yahwah with a muscular body that sprays HANK on the window. Jet is surprises to see his Pentagon codename on the window. Yahwah says in Jet's case, his real name suits him better, and for his old Pentagon buddy in here, his codename suits him better. And Yahwah asks how Jet did Quanx end up as enemies from being friends, and they'll kill each other if he ever identify himself. At this time, a blackout occurs. Jet thinks how deep does Silverquick know about Pentagon, and he doubts whether the person in here is Eldgon or Randolph. Then, when the electricity came back, Yahwah laughs that Randolph has doing well, and Jet is surprises.
