Ben look back at the group

Ben : Eon is essentially a psychopath. He is willing to mess up the timelines just to get what he wants, and if he can't rule, he is willing to destroy all of existence. He apparently has a long history with and a deep hatred of Paradox . Eon is willing to work with others when their goals will benefit him in some way or they offer a reward 

The group  just shocked about Ben  just explain about Eon

Zoey : does he have the Omnitrix or Ultimatrix ?

Ben : Well according to Professor Paradox , Eon originally had an Omnitrix , but something bad happened to it, and he integrated the leftover parts from it into the device on his left arm.

Bill : What kind of power does he have ?

Ben :  Eon can travel through time, including to alternate timelines and dimensions. He can project time rays that can age almost anything to dust. He  is capable of teleporting and opening time portals. He also capable of producing an energy sword, and can fire beams of energy. Eon is able to sense the sotobro effect caused by Clockwork

Ben : I think he teleporting  himself to other timeline

Francis : Ben, can you tell us a bit about Eon , how you win him ?

Ben : Um...sure , Eon was sent to Earth  to activate The Hand of Armageddon .He was too old to activate the Hands and grew older with each jump through time , so he hunted the Omnitrix or Ultimatrix wielder to duplicate his DNA and control them, but was stopped by  Paradox every time. 

Ben : He used ape-like aliens as henchmen to help him in his search for the Hand of Armageddon. When Eon found that he was indeed too old and weak to activate it himself, he set about capturing me , with the intention of using the Omnitrix to turn me into a young Chronian,  upon succeeding in this goal, Eon left the scene,

Ben : He say : "two cannot exist in one world". 

Ben : As Chronian, I activated the Hand of Armageddon, but regained control when Gwen talked to me and turned back to normal while Max deactivated the Hand of Armageddon. Enraged, Eon returned and tried to exact his revenge, but I become Wildmutt managed to throw Eon into the Hand of Armageddon, destroying it in a huge explosion of bright, glowing purple-colored energy . Eon eventually returned and is revealed to be an alternate future of me

Ben begin to tell The group about his future self

Later

Everyone : Yeah!!!

Zoey  unlock the door , the group move out the saferoom
