I agree with xcolbyx, except on 1 part. The AI was trying to turn itself on. It was hunting in it's memory for password fragments (it has access to all the computers in the base). It's extra high processing power lets it do this without noticeable passage of time (hence, time freeze). Once it found the password, it reactivated itself and proceed to destroy all the world's weapons as it wanted to. Not sure how the infinite ocean fits in though.
You know... Sometimes this games makes me go around finding coins before I put out the fire. In fact, I'd leave something burning to collect the coins before finishing it off.
For the card, try Time mode. Spam down when not in bird zones (there are certain areas where the birds will only show) to get there quickly.Slow down and catch the bird when it shows up.
Heh, I have a Uber Combo myself. Lots of attacks + Burning (Chaos special). That oneshots anything. Is countered by Absorb attack though. Mana shield just delays for 1 round.
There are actually a LOT of reactions. You just don't see them cause you can get all 115 without some of them. I tired brute forcing the thing, and there are many reactions and funny quotes.
