When Should I Evolve Gloom in Pokémon FireRed?

As an experienced FireRed player and Grass-type enthusiast, I recommend waiting until level 46 when Gloom learns Solar Beam before evolving it. This allows Gloom to get the most value out of one of its strongest STAB attacks.

Evolving too early means missing out on moves that can really boost Gloom‘s battling capabilities. So be patient and you‘ll have a powerful Grass/Poison-type for your Kanto adventure!

Evolving Gloom Too Early Has Big Drawbacks

Many players just grab a Leaf Stone as early as possible and immediately evolve their Gloom without considering the disadvantages:

• No Solar Beam: At level 46, Gloom learns one of its best moves. Miss out on this, and you lose a huge piece of its potential.
• Earlier weakness gains: Gloom starts picking up some handy resistances around level 40. Evolve sooner and you skip out on these.
• Reduced move pool: By waiting longer, you expand the variety of grass and poison moves Gloom can learn before evolution. More options to tailor to your battle style.

I‘ve made this mistake. An unevolved Gloom with Solar Beam is more versatile and hits harder than my early-game Vileplume that missed out on the key move. Learn from my experience!

The Solar Beam Difference

Solar Beam is a total game changer for Gloom‘s viability in FireRed. Here‘s why it‘s so important:

• STAB damage: Gets same-type attack bonus (STAB) because Grass-type matches Gloom‘s typing
• Sheer power: With 120 base power, it‘s Gloom‘s strongest special attack by a huge margin
• Coverage: Devastates Water-, Rock-, and Ground-types that wall Gloom‘s Poison moves
• Enables sweeps: Can plow through unprepared teams after a Growth or two

And if you evolve into Vileplume, it only gets better:

• Higher Special Attack: Vileplume gets a 30 point boost to further amplify Solar Beam
• Sunny Day synergy: Pair with Sunny Day to remove Solar Beam‘s charge turn and blast opponents

Losing access to Solar Beam via early evolution leaves you with an incomplete Pokémon. You miss out on so much potential without Gloom‘s signature nuke in your back pocket!

Evolution Changes Stats and Movesets

Before deciding when to evolve Gloom, compare how it changes based on the evolution path:

Vileplume

Gains Special Attack and Special Defense
Physical moves become less viable

Moves Lost

• Petal Dance (Level 66)

Moves Gained

• None

Vileplume loses a powerful physical grass move in Petal Dance but becomes an even stronger special attacker. Solar Beam fits very well here.

Bellossom

Focuses on Speed and Attack
Special moves lose viability

Moves Lost

• Solar Beam (Level 46)
• Sludge Bomb (Level 48)

Moves Gained

• Magical Leaf (Level 22)
• Quiver Dance (Level 33)

Bellossom shifts toward an evasive and disruptive physical moveset. It loses STAB special attacks but can still hit hard with Flower Power boosted by Quiver Dance.

Based on the changes above, think about whether you want raw special power or speedy physical strikes after evolution.

Community Input on Gloom Evolution Timing

Looking at popular online Pokémon forums and guides, high level players offer similar advice around delaying Gloom‘s evolution:

"WAIT for Solar Beam. It carries hard." – @elite4champ

"Petal Dance on Vileplume and Magical Leaf on Bellossom just doesn‘t hit the same." – @proff_oak

"Gloom‘s mid-evolution movepool is too good to miss out on!" – Smogon forums

The consensus seems to be riding out Gloom‘s mid-level spike in viability before evolution. Solar Beam and Petal Dance are just too appealing to pass up.

I agree wholeheartedly from personal experience. My end game Vileplume pack much more punch after letting Gloom run wild with Grass nuke moves prior to using the Leaf Stone.

When To Pull The Trigger on Evolution

So when exactly should you stop waiting and finally evolve your Gloom? Here is my personal recommendation:

• Wait until level 46 for Solar Beam
• Immediately evolve into your choice after move learns
• Consider holding Everstone before then to prevent early evolution

You really want that Solar Beam power spike. My preference is to evolve to Vileplume right after getting it to maximize special attacking prowess. But either path works great at level 46.

If you just can‘t wait, I‘d say mid-30s is absolute minimum. Any earlier is leaving a lot of potential on the table. Have some patience and you‘ll have a complete monster on your hands soon enough!
