Your Current Moveset:
* Fly: Great for aerial coverage and getting around the battlefield.
* Dragon Claw: Strong STAB move (Same Type Attack Bonus), but lacks power against some common threats (like Fairy-types).
* Flamethrower: Another strong STAB move, but lacks accuracy.
What's Missing:
* Coverage: You need a move that hits common Pokemon your current moves struggle against.
* Accuracy: Flamethrower's low accuracy can hurt in crucial moments.
* Power: Dragon Claw is good, but there are stronger options.
Suggestions for the Fourth Move:
1. Heat Wave: This is a high-powered special move with great coverage. It hits hard, has good accuracy, and is a powerful alternative to Flamethrower.
2. Overheat: This is the most powerful fire-type move, but lowers your special attack for two turns afterward. This is a high-risk, high-reward option.
3. Solar Beam: This is a powerful move that requires one turn to charge, but it hits very hard and has great coverage.
4. Dragon Pulse: A stronger Special STAB move than Dragon Claw, and it has better accuracy. This is a great choice if you want to focus on Dragon-type moves.
5. Earth Power: This ground-type move offers excellent coverage against Electric, Rock, and Steel-type Pokemon. This is a good option if you frequently face those types.
Which Move Should You Choose?
* For general use: Heat Wave is a great choice for coverage and accuracy.
* For maximum damage (with risk): Overheat is your best bet.
* For powerful coverage with one turn delay: Solar Beam can be devastating.
* For stronger Dragon-type moves: Dragon Pulse provides accuracy and power.
* For coverage against common threats: Earth Power is an excellent option.
Consider these factors when deciding:
* Your playstyle: Are you aggressive and want to maximize damage? Or are you more strategic and want to ensure hits?
* Your opponent's team: What Pokemon are you likely to face?
* Your Charizard's nature and EVs: Is your Charizard special attack focused?
