Back at Monarch HQ, King Wither had arrived to tell all about what he knows about Bagan.

Jennifer: your saying, you Witherkaiju and Enderkaijus, know more about Bagan and where he came from?

Wither: yes, Bagan came from another universe, a dark alternate universe. He revels only in destruction and doom, his dark energy allows him to bring destruction to all who oppose him. 

Daniel: when the Guardians fought him, they managed to harm him, but not as good

Wither: it's because it was night time, he is a being of darkness, light is his destroyer, but simply fighting him in daylight won't be enough.

Jacob: right..we better get this information to the Earth Defenders

Kiryu: leave that to us, anything else known about Bagan?

Wither: you may think he is immortal, the truth is, only half

Jet Jaguar: what does that mean?

Wither: though he is immortal, he can be killed, permanently, if all matter in his body is completely vaporized, he will never return, his spirit gone into the afterlife.

Zone Fighter: but like that's going to be easy...where is Bagan now?

*a siren blared, detecting Bagan on the radar*

Monarch operative: Bagan detected! heading for Infant Island! 

Kiryu: what!? All Mechas! let's move!

Kiryu, Kirya, MOGUERA, Jet Jaguar, Zone Fighter and Mechani-Kong flew up and out of the base, quickly heading to Infant Island!

on Infant Island, the natives, and the chidlren: Godzilla Jr, Mothzilla, Gothra, Portal and Princess Ghidorah, are unaware of Bagan arriving on the shores...
