(Mason is seen in the hosptal room, standing next to Martin, who is still recovering.)

Mason: Kei Fukuide... what are you planning to do this time?

(Cut to Central City, The Flash is seen having arrested his "Rogue Gallery" again as Kei is watching them.)

Kei: The Flash, huh? Time to give you a real villain to fight.

(He smirks as his eyes glow, and then he pulls out a Kaiju Capsule.)

Kei: Eleking!

(He activates a capsule, and Eleking's screech is heard as he places it on his Loading Knuckle, and then he pulls out another Kaiju Capsule.)

Kei: Ace Killer!

(He activates a capsule, and a thunderclap is heard as he places it on his Loading Knuckle, and then he pulls out his Riser and activates it.)

Kei: Now I shall mark the end!

(Kei scans the capsules with his Riser.)

FUSION RISE!

(He presses the button and prepares to transform.)

ELEKING! ACE KILLER! ULTRAMAN BELIAL: THUNDER KILLER!

(Kei transforms into Thunder Killer and shoots at Flash, who quickly evades his beams.)

Flash: Wow! It's that giant monster who attacked Chicago earlier. I better warn Green Lantern about this!

(Back to Mason, he is seen still watching Martin's recovery until he hears about Thunder Killer attacking Central City, and then he decides to transform into Ultraman Zero. Some seconds later, he arrives at Central City and prepares to fight Thunder Killer.)

Zero: I am Zero! Ultraman Zero!

(Thunder Killer gestures Zero to charge at him, and he does so as he hits the monster with a knee strike before dodging his attack and kicking his chest. Once Zero hits Thunder Killer with another knee strike, the monster slashes him and hits him with a tailswag, bringing the Ultra down.)

Zero: (gets up) I won't lose!

(Zero summons his Ultra Zero Lance.)

Zero: CRESCENT SLASH!

(Zero slashes Thunder Killer, making the monster back away. Zero then changes to his Luna-Miracle Mode. Thunder Killer shoots his beams, but Zero deflects them while dashing as he slashes the monster again.)

Zero: You're 20.000 years earlier to beat me!

(Zero keeps dashing and slashing, bringing Thunder Killer down. Zero then executes one of his finishers.)

Zero: MIRACLE ZERO SLUGGER!

(Zero generates three pairs of his Zero Sluggers, controlling them all mentally as they slash Thunder Killer, destroying him. Zero then flies away.)

(The chapter ends with Martin finally having recovered as his four girlfriends come and visit him.)
