Normal Metroids not Prime can be dispatched rapidly by using Freeze Beam followed by a missile.
Defeating Chozo Ghosts easily
Shoot two Super Missiles to kill Chozo Ghosts. Also, if you have the X-ray Scope, you can maintain a lock on them.
Defeating Flaahgra
The trick is to knock down the light-reflecting mirrors and bomb the plant away. At first, there is only one mirror that reflects the light and helps grow the plant. Fire at the Boss with normal fire rapidly until it is stunned; there is no need for heavy firearms. It will not be able to attack you at all if you stun it on time. After the plant Boss is stunned, run to the one reflecting mirror and shoot the red target behind the mirror with either a charge beam or only one missile. The plant will shrink and its spiky roots will vanish. Roll into a ball, go into where the roots were protecting, and drop a bomb. The plant is killed, but returns with two mirrors. Do the same thing with two mirrors, then three mirrors, then finally four mirrors. After finally killing the plant, the Varia Suit is yours.
Defeating Elite Pirates
When the Elite Pirates burst out of containment, switch to your normal beam and build up a charge shot. When the Elite is not trying to absorb energy, fire a Super Missile at them. Two Super Missiles will take them down. Use the following tactics to defeat the different kinds of Elite Pirates at the Phazon Mines. This is a very difficult area due to switching beams for certain pirates:
Power Troopers
Use Normal Beams or charge a Normal Beam at it three to four times.
Wave Troopers
Use Wave Beams or charge a Wave Beam at it two to four times.
Ice Troopers
Use Ice Beams or charge an Ice Beam at it and finish it with one missile.
Shadow Pirates
Use the Thermal Visor to see them. Use Wave Beams or charge a Wave Beam at it at full force two to four times; or, fire with ease with the Plasma Beam.
Plasma Troopers
Fire at them with your Plasma Beam three or four times. Hide behind a wall and the Plasma Beam will end up finishing them with its burning effect. Do this to other pirates as well, even though they only need about three shots to be killed, only about one will evaporate them if you just wait patiently.

Easy kills
Flying Pirates, Gun Turrets, and most non-mini Boss type creatures can be taken out by the Ice Beam followed by a missile.
To easily take down enemies under hard mode, use the following strategy. Charge up Wave Beam or another weapon with stun capabilities, fire it at the enemy, shoot a missile, then repeat. This will use up a lot of missiles, but is vital for getting through long parts, such as the Phazon Mines or Research Facility.
When confronting flying or very quick enemies, such as a Flying Space Pirates, Metroids, Stealth Pirates, etc., use your Wave Beam. The Wave Beam, unlike the other beams, homes in on the target you locked on to. When using a different weapon, it is easy to miss. Also, if you charge up the beam, your enemy becomes stunned for a few seconds, allowing you to get in another good shot or two. Missiles can also be used, but should be conserved. Sometimes, if you are very close to an enemy, you may want to use a Charged Ice Beam. This freezes your enemy for a longer time than the Wave Beam stuns them. However, this is risky.
To kill birds easily, when you enter a room with a War Wasp hive, shoot the clustered part of the hive with a missile. It will explode, and the War Wasps can escape.
To defeat ice creatures easily use the Plasma Beam or Flamethrower. It can kill most ice enemies, including Sheegoths, with only one or two hits.
