I'd like to jump in if there is room, I'll need to catch up on the story befor I start adding however.
Ok please let me know if this is no good.
Name: Moby Dick
Height 400 feet (From the highest point of his back)
Emergence: Emerged from in the Amazon Rainforest. Satellites over the continent identified the sudden apperances of a massive heat signature. This was suspected to be a kaiju emergence but due to the location and a variety of other factor no military force could be sent to engage, however a recognisance team was sent to assess the situation. They discovered the kaiju that would be called Moby Dick. After emerging, Moby Dick commenced eating the Amazon Rainforest and is causing massive ecological damage.
Personality: Aloof and Indifferent, Moby Dick is a walking (well plodding) mountain who's primary goal it to satiate his titanic hunger. He spends his time making his way to his next meal with everything in the way gets trampled or ploughed through. That said he's generally peaceful and doesn't go looking for fights, he just wants to be left alone to eat in peace. Unfortunate for every party involved, his indifference and single mindedness can very easily cause trouble as he wont think twice about trampling through other Kaiju's territories and dens.
When threatened Moby Dick will generally make a show of his size and strength to deter his would be attacker. If this fails he gives them a quick blast of his breath weapon in an attempt to make the point. If the other kaiju is really dead set on fighting after this point, Moby Dick doesn't, and really cannot, hold back and hits his foe with every ounce of power he's got.
Moby Dick's primary food source is plant matter, which is why he always heads for densely forested areas. That said he will ingest stones (big freaking boulders) and take the odd bite out of buildings to help him digest his primary food.
Size: Moby Dick is big, even by kaiju standards. His size alone can discourages attackers and anything that tries to attack him head on is at risk of being trampled. This also means that despite the fact he's not interested in destroying cities, he cannot help causing a lot of damage when passing through.
Hight Body Temperature: Moby Dick's body temperature is very high, to the point that ice rapidly melts on contact with his skin. Steam can regularly be seen rising from his body.
Whip Tail: His primarily weapon in combat, Moby Dick's tail is a deadly whip capable of slicking buildings in half.
Stomp: Moby Dick's most powerful attack. He rears up on his back legs, then bring his front legs (plus all his weight) down on his target.
Scolding Spout: Moby Dick shoots a stream of scolding hot steam from his mouth. This attack is not ment to be lethal, instead it's ment to simply hurt, blind and confuse his enemies. That said it packs enough force to knock other kaiju over if they cough off guard and down flyers if they take it full on. It has it's uses in combat also, as it can leave his opponent vulnerable to attack if they are close enough. For humans however this attack is a lot more dangerous, with people being boiled to death, vehicles sent flying and buildings blasted apart.
Walking Ecological Disaster: Moby Dick's hunger causes him to consume large sections of forest at a time, which can lead to the destruction of entire ecosystems.
Slow: Very, very slow. He's got two speeds. Plodding and plodding slightly faster. He's a bit faster in water but thats not saying much.
Big Target: It's vertually impossible to miss him with an attack, he's that big and slow.
Always Hungry: Moby Dick must constantly search for food to fuel his massive body.
