The final leg of Digimon World 3. After spending the entire game in the Digital World. You're in a satellite in the real world. You fight your way through this onslaught of tough enemies and boss fights. You get to the guy you think is the final boss. After a fight, his partner Digivolves, devours him and then fuses with Satellite with the intention of fusing with the Earth to become Gaiamon. So all of sudden you go from fighting this Megalomaniac to being the only standing between Earth and total destruction. And then during the actual fight, the camera will sometimes pan around and you see the Earth behind you. After the first phase of the fight is done he fires a shot at the Earth and your partner takes the hit. I had a Seraphimon the first time I did it too. Then you move in for the final fight and it does my favorite anime trope and starts playing the opening music.
