CHAPTER 1 :- ENTERING OMNIVERSE
(PS NOTE :- This chapter is for information on during which event Goku appears in Ben 10 omniverse)
The scene begins with Ben, in his Atomix form, crashing into the Rooter base. He greets Kevin, who responds by saying, "Ben, you've made some boneheaded moves in your day." Ben retorts, "It's good to see you, too." Kevin glares at Ben, clearly annoyed.
Gwen enters through the hole created by Atomix on a Mana platform, carrying Rook, Argit, Zed, and the Amalgam Kids with her. Kevin is angry that Ben brought them to the Rooter base, despite his efforts to keep them away. Gwen acknowledges Kevin's note, which he finds sweet, but Kevin insists that's not the point. Alan interrupts, suggesting that Kevin should thank them for bringing backup.
Servantis then appears and thanks Alan, electrocuting Kevin and the Amalgam Kids with three jolts of electricity. He explains that he has reconnected their psychic link to Kevin, and orders the children to keep the rest busy while he takes Kevin away to speak with him.
Ben sarcastically comments on the situation, but the Amalgam Kids warn Gwen, Rook, and Argit to leave while they fight with Ben. The battle intensifies, with Servantis trying to convince Kevin to finish his assigned job. Suddenly, between Kevin and Ben, a mysterious person named Son Goku appears. Kevin bumps into him and falls, asking who he is ?
Goku introduces himself ," You guy's can call me Goku and I am here for someone named Ben Tennyson." Ben looks at Goku in a confused manner ," Why you're looking for me ?"
