Hint: Defeating Reapermon:
Choose Wormmon and use Silk Thread (Triangle) or Stingmon and use Spiking Strike (Triangle).

As a rookie, do as much damage as you can and when you digiolve do the same thing, but use R1 before your blast gauge is almost gone.

Use these Digimon: Gatomon (Tailmon) or Patamon. Move right or left by using Lightning Claw or Slamming Attack, then move in the opposite direction still using that attack to eventually defeat him.

Hint: Easy win with Impmon:
Confuse the enemy (Square + Forward) when your bar is full to digivolve. As soon as they become confused, digivolve to Beelzemon, and use Chaos Flare. The opponent will not be able to move while it is confused. Doing this will make it easier to win.

Hint: Easy win with Reapermon:
In the Reapermon stage, as soon as the match begins, start with a Grim Slasher. Just before the Grim Slasher attack finishes, do a Bone Duster attack. Your opponent will be confused. Go up to your opponent when he is confused. Do the combo again and he will be confused once more. Then finish off your opponent with a Bone Duster attack.

Hint: Starting moves:
For best results when fighting Digimon, the following are good starting and backup moves.

Agumon: Use Claw Attack (Triangle) and then when they get up, press Square(3), pause very briefly, then and press Up + Square (a four combo).

Gabumon: Use Blue Blaster (Circle) and back it up with Horn Attack (Triangle). You can use it twice if desired.

Omnimon: Start out with Transcended Sword (Triangle), followed up by Garuru Cannon (Circle).

Patamon: Use Boom Bubble (Circle), Slam Attack (Triangle), and then physical attacks (tap Square for repetitive physical attacks).

Reapermon: Use Grim Slasher (Triangle) and before the combo runs out, quickly press Circle for Bone Duster.

Renamon: If you are far away from them, press Circle for Diamond Storm, and run behind them so you can attack them for a 20 combo.
