Immortality

Initially I had though perhaps Level 40 Solo Soldier would have been a good fit, hence the reason my 4E version of the Cloverfield Monster was a Level 36 Solo Brute. However, converting using my 3E to 4E converter (which you can find here) it seems as if the original converts to Level 35, which would mean the Cloverfield Monster should really convert to Level 31 or thereabouts (thinking it should be about Level 33 though).

The stats for Godzilla are interesting in that they raise the issue of how powerful nuclear weapons should be in 4th Edition. What we have to remember about 4E is that hit points (and therefore also damage) are relative. 1 hit point means something different at Level 30, than it does at Level 1.

For those keeping track of sizes, I suggest the following (I should note that the following stats for Godzilla don't use the full extent of the Mega-Damage Rules which will be included within the Vampire Bestiary. I may comeback and fix these stats after that book is released):

Levels 7-8 = minimum for Large
Levels 15-16 = minimum for Huge (Huge monsters should nearly always be Elites)
Levels 23-24 = minimum for Gargantuan (Gargantuan monsters should nearly always be solos)
Levels 31-32 = minimum for Mega-sized monsters (as big as a castle)
Levels 39-40 = minimum for Giga-sized monsters (as big as a mountain)
Levels 47-48 = minimum for Tera-sized monsters (as big as a planet)

Use of 'Godzilla' here is not done in the course of trade and is not intended as a challenge to any trademarks.

Atomic Damage

These attacks deal damage on multiple levels, even going so far as to disrupt the targets very molecules. Atomic damage imparts a vulnerability (to all damage) equal to the damage itself. This vulnerability lasts until the target makes a successful saving throw and does stack with subsequent atomic damage.

e.g. If Godzilla's Atomic Breath deals 50 damage. That target loses 50 hit points and now has vulnerability 50 against all attacks (save ends). If Godzilla then stomps the target (before they have saved against the atomic damage) they take the stomp damage plus 50 (from the breath).

Standing over 300 ft. tall, this great reptile almost rises into the clouds. Its hide is covered in thick dark green scales, its back ridged with pale bone-like plating tapering down the length of its tail. With menacing glare and mighty roar it issues its challenge of supremacy.

Details of Godzillas history can be found at the fantastic Rodans Roost website here.

Megasaurs

The term Megasaurs can be taken as refering to any creature larger than Titanic size (also known as Colossal+).

Megasaurs vs. Modern Weaponry (Low Physical Factor World)

Even main battle tanks (100mm cannon) will likely prove totally ineffective against megasaurs and be ignored. Battleship guns (400mm cannon) may just irk the great monsters enough to warrant their attention. Basically you need nuclear munitions to seriously stop megasaurs, of course then you have to contend with the collateral damage and radiation likely just as bad, perhaps worse than the damage the great beasts would have inflicted anyway. Also the fact that Megasaurs are often mutated from nuclear radiation means that atomic weaponry doesn't always have the desired effect on them. Hence the reason state of the art conventional weaponry is the preferred method of anti-megasaur equipment.

Japans Self-Defense Agency (JSDA) employ Super-X Main Sky Battle Tanks, whereas the United Nations Godzilla Countermeasures Centre (UNGCC) G-Force have Electron Cannons, Maser Tanks and two mechas: MechaGodzilla and MOGERA. Consider Earth to be at Progress Level 6 for the purposes of representing the Toho movies using d20 Future.

It should be noted that the Toho Godzilla seems to exist in a low physical factor world since it just laughs off conventional weapon attacks.

Megasaurs vs. Modern Weaponry (High Physical Factor World)

Ignore the Mega-size rules.

It should be noted that the Hollywood Godzilla seems to exist in a high physical factor world, since it was taken down fairly easily by a couple of jet fighters.

Megasaurs vs. Epic/Immortal Campaigns

Introducing megasaurs into fantasy settings may be an interesting way of reshaping the geography. Only epic level characters, monsters or deities can stand against them. Perhaps special Councils have been set up to deal with the menace of megasaurs, employing epic level agents formed into assault teams, charged with the subdual of the great beasts.
