Dragon Ball Super (2015), S01E021: The Revenge Begins! The Vicious Freeza Army Attack Gohan!
Freeza and his army arrive on Earth, where Gohan, Piccolo, Kuririn, and the others had gathered to hold out until Goku and Vegeta return. Freeza says that he has waited a long time to have his revenge, and that he wishes to face Goku. Seeing as how Goku is not present to help, Freeza orders his army to attack the Earthlings. His army proves to be no match for the fighters; even for Kuririn, who had given up fighting. Disappointed with his lackluster army, Freeza orders Sorbet to send in his elite soldier, Shisami (シサミ), to take out Gohan. Suddenly, Tagoma fires a beam at Shisami and Gohan, killing the former and badly injuring the latter. Sorbet is surprised by Tagoma's newfound power which he had achieve training with Freeza. Freeza promises Tagoma the command of his army if he takes out the Earthlings. He accepts and prepares to fight the Earthlings. Meanwhile, Goku and Vegeta, oblivious to what is happening on Earth, continue their training under Whis.
