Getting back on topic, I finally managed to pull up Lavos' stats in each battle. Check this out.
1999 AD Lavos
Lv: 15 (Yeah, only 15!!! Imagine if he was Lv99! Even the Core is only Lv50!)
HP: 10,000
Attack: 73
Defense: 127 (which is standard for most enemies)
Magic: 1
Speed: 12
Evade: 20
Magic Def: 50
Compare that with:
Ocean Palace Lavos
Lv: 20
HP: 30,000 (3 times as much!)
Attack: 180 (More than double)
Defense: 127 (standard)
Magic: 2
Speed: 16 (so, 33% faster)
Evade: 11
Magic Def: 50
3 times as many HP, more than double the attack power, and 1/3 more speed spells OUCH.
Just for your amusement, check out the stats on these too:
Lavos Inner Body (not counting the arms)
Lv: 50
HP: 20,000
Attack: 45

And these stats for the Lavos Core:
Left Bit
Lv: 50
HP: 2000
Attack: 40

That spells pushover. Next...

Lv: 50
HP: 10,000

The maximum for attack power is 255...and he's only at 100! That slap hurts enough as it is. Ouch... And now for...
