Jack battles Earthtron to the death in "Ultraman Jack". Fair Use, as I am in no way making money off of this. This is meant solely for entertainment use only. This does not belong to me, and I am not affiliated with the creators.
I've started on this thanks to Mill Creek! I like the name Earthtron more...since it's implied he came from undergroun. Astron makes him sound like a space monster.
@Irrelevant402 I must agree: ‘Earthtron’ DOES sound more appropriate since he IS an Earth kaiju. And like you, I am totally grateful to Mill Creek Entertainment for putting out ‘Return of Ultraman’ & ‘Ultraman Ace’, along with their three other predecessors on Blu-Ray disc. These classic tokusatsu series deserve to get the proper release treatment!
Stupid? Izenborg and Ultraman both have the same concept of giant monsters destroying cities so a some kind of a patrol or something tries to fight them off but when they can't handle it, the giant hero appears and fights the monsters. The only difference in Izenborg is that it's half live-action and half animation and the first bunch of episodes had no giant hero in it.
