When an enemy throws a building or anything else, press L to catch the thrown item.
When you are down, press X or B to do an attack on the ground.
When in the Mothra larval stage, fight your opponent as long as you can. When you are just barely out of health, transform into the butterfly stage. You will have full health and have another chance to defeat your opponent without starting over.
In any mode, you can defeat enemies with Anguirus quickly by doing this combo of attacks (in any order): press Down + B, Y, A, Grab. When you Grab, press Toward your enemy, then do a drop kick. Repeat this in any order to quickly defeat the enemy.
All you have to use are the B, X, and some A attacks to defeat your enemies. Note: Grabbing, then pressing B is not a good idea, because its gives your enemy health.
When playing as Jet- Jaguar and you are having a hard time fighting your opponent, make yourself small. By doing this, you will be invulnerable to laser attacks, be able to run extremely fast, and your attacks are faster than any other monster.
Press Away + A, then hold White + Black once they are off the ground from the first hit. If you win a beam fight, immediately afterwards tap R. Make sure to use beam attacks once in a while. Tail, fist, and booster attacks are good combos to do some damage. When you get the chance, grab and have him use the eye laser. It is good for a grab attack. Repeat in any order desired. Use circle sweep for a good knock down, but jump back for dodging the ground recover moves that your opponent does.
When low on energy, grab the enemy and take some energy. Then when it is high enough to do a beam attack, do so. It will cause a lot of damage. Keep attacking and grabbing to quickly win the battle.
Press Down + B, then press Away + B. Keep doing this until you are close to your enemy to hit them.
Moguera tends to run out of energy very fast. It is a good idea to have Moguera shut down and recharge a few times before fighting again, but do the following for a quick win. While on treads and moving, fire some missiles and purple beams to do a ttle damage. Then, hold X and do the isomorphic drill and tap B and any weapon attacks. After that, recharge and repeat the process. After some time you can toy around with his way of combo attacks and pattern. He does best with patterned attacks.
Have Space Godzilla make two crystal pillars, then start to attack with crystal beams and mini crystal balls. Also, run around with him. This will save you the trouble of getting hit. Then, just experiment with the attacks until you find a good combo. Note: When your pillars are broken, make new ones quickly.
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.
Run when he digs, or you will be thrown. Watch out for his long range attack, it is powerful. Also watch out for his attack that stuns you. Try to stay away from him, and when he is done attacking or dazed by digging, try to execute a powerful attack.
Orga will attack you while your on the ground, can throw you, and is extremely tough. Try to keep out of striking range of Orga. Also try not to be shoved on the ground or he will belly pound you. Use strong physical attacks to defeat him.
Use strong physical attacks and strong long range attacks; or use Orga or Destroyah.
