Is Shin-Gojira living on borrowed time?

Well I would say yes, based on the design, but from reviews and comments I've read about the movie, without giving too much away, I'll say that doesn't seem to be the case with this Godzilla.

Of course I  can't really say since most of the reviews were from english speaking viewers who nothing to a tenuous grasp of the Japanese language and it's apparently very dialogue heavy so something of this might have been addressed in the movie and no reviewer picked it up.

Judging from what I've read and seen, he's actually getting stronger. They weren't kidding when they said this is the most powerful incarnation of Godzilla yet.

DURP004 - That is an extremely interesting and very feasible theory! It causes me great curiosity, for I wonder just how many of the American/Brittish/EU moviegoers who went abroad to watch the opening for Shin-Gojira were capable of understanding the dialogue in full. Very compelling! :)

WOLFGUY - Now that is exceptionally interesting information! If Godzilla is growing in strength, perhaps the radiation that suffuses his body is leaving him in a state of constant mutation? :)

As far as SPOILERS go, he actually has a lot in common with Hedorah from what I've heard.

He has EVAUnit01 Atomic Breath which means he can only get stronger at the cost of easier fatigue & falling into a relapse state here and there (logically speaking) ^_^

WOLFGUY - Hedorah? Really?! Does he change at any point in the film? :)

MIZIKAME - That is extremely neat! I am so very excited for this film! :)

He apparently starts off as a tadpole/lizard-like creature and evolves throughout the film, absorbing any and all organic matter and growing throughout the film.

^Only partially true.

I just know what I've read.
