What Must Be Defended

is the eleventh episode of Ultraman Z.
==Synopsis==
SSA-3 King Joe STORAGE Custom is finally complete! With weapons equipped to every inch of its body, this super robot wields tremendous power. Meanwhile, Red King appears before STORAGE. It seems, however, that this Red King has a secret...
==Plot==
On the day of his father's death anniversary, Haruki receives a day off from Hebikura to visit his mother's house in Fukama City. The newly finished King Joe STORAGE Custom was assigned to Yoko, who scored well in her simulation test. Meanwhile in Fukama's quarry, the construction workers discover a hole and a raging creature inside.
Haruki has a flashback of playing baseball with his late father back in his childhood. The quarry's explosion lead to the appearance of a Red King, forcing him to evacuate everyone else to the shelter while Yoko arrives in King Joe. Seeing a young boy alone in the middle of the chaos triggers his memory of losing his father to a Giestron rampage during his elementary school years. After rescuing the young boy as Beta Smash, Z was joined by King Joe STORAGE Custom/Yoko into fighting the lone monster, before she left off to fight the other one nearby the quarry. Once accessing Alpha Edge, Z uses the Ultra Medal attacks to kill Red King and join Yoko at the quarry.
In Gamma Future, Z is able to outclass the other Red King with his energy attacks. Z spots an egg within the quarry the Red King came from, thus revealing that it was only trying to protect its unhatched child. This revelation horrifies Haruki once he realized that the previous Red King was a father, which makes his murder of it none the different with Giestron's attack in the past. The terrified Haruki was brought to his knees and protected the lone Red King from King Joe's firepower (while overloading the SAA unit in the process).
The Red King had since migrated with its unhatched child to somewhere else, but Hebikura notes that the child will possibly targeted mankind once its finally grow up. Haruki left his hometown that evening, but the memories he had with his father still remained in his mind.
