In any playing mode, you can defeat enemies with Anguirus quickly by doing this combo of attacks (in any order). Press Down + Circle, Triangle, X, grab. When you grab, press Toward your enemy, then do a drop kick. Repeat this in any order to quickly defeat the enemy.

When you are down, press Square or Circle to do an attack on the ground.

When an enemy throws a building or anything else, press L1 to catch the thrown item.

Bonus: Orga: Combo
Bounsing Paralyzer: As Orga, grab an opponent and press O. Orga should throw the opponent downword and the opponent bounce back up in the air. At the right timing(make shure you have enough energy) press R1 to shoot out that green thing. If the opponent falls down fast enough he sould be paralyzed (or stuned). You'll have enough time to make another attack.

Press and hold L2, then Circle, then R2 in that order, then let go of them starting with Circle, then R2, then L2.

Successfully complete the game under the hard difficulty setting.

Make sure he does not jump on you, or you will get hurt very badly. When he tries to jump on you, try to attack him. However, he is very fast. Try using Megalon to dig under him to defeat him. Use any strong monsters, or any fast monsters. Note: He can regenerate energy fast to use his fire breath quickly. His fire breath cannot be made into a long range attack assault. He can also dig.

Destroyah is one of the toughest monsters in the game. He can use an oxygen mine and you will be flying all over the place. However, it only goes in one direction. His only weakness is his lack of speed, but he is still very strong. If you can attack him at the correct moment, avoid his oxygen mines, and avoid his attacks, you can defeat him.

Stay away from Mecha King Ghidorah and use mostly long range attacks. After five or more long range attacks, he will be defeated. However, only do this at the correct time or he will gain health.
