Torchwood, a classic support-and-buff plant in Plants vs. Zombies, centers on boosting Peashooters with doubled damage and splash effects.

I. Basic Information for the First Generation

• Sun Cost: 175

• Cooldown: 7.5 seconds (fast)

• Health: 300

• Unlock: Adventure Mode Level 4-4

• Planting Locations: Ground, Flower Pots, and Water Lilies; cannot be planted on rooftops

II. Core Effects (Must-Memorize)

1. Ignite Peas: Regular Peas that pass through transform into Fire Peas, doubling their damage and adding a small-area splash effect.

2. Counter Ice Effects: Frost Peas that pass through revert back to regular Peas, losing their slow effect; they do not share the same firing line as Ice Melons.

3. Dispel Fog: Clears fog in small-area foggy levels.

III. Second-Generation Enhancements (Chinese Version)

• Tier 1: Base effect—doubled damage plus splash.

• Tier 2: Sturdy Shield—health increased to 1,500 (5x base), providing enhanced durability.

• Tier 3: Life Boost—health boosted to 4,500 (15x base), turning it into a “meat shield.”

• Tier 4: 50% chance to trigger ultimate ability upon planting, granting permanent Purple Fire; Purple Fire Peas deal double damage (total quadruple), and Jokers cannot bounce them back.

• Ultimate Ability (Energy Bean): The entire plant emits blue or purple flames, further doubling pea damage.

IV. Practical Pairings and Usage

• Best Companions: Pea Shooter, Double Pea, Triple Pea, and Machine Gun Pea, forming the classic “Torchwood + Pea” damage-dealing lineup.

• Lineup Tips: Plant on the right side of the Pea Shooter’s firing line (so bullets can pass through), one per row, with front-row Nutmegs providing protection.

• Countering Relationships: Vulnerable to ice-based attacks, giant impacts, and Joker bounces (though Purple Fire can mitigate these).

V. Fun Fact

• Character Profile: Honest and upright, values friendship, and is widely respected for its ability to enhance Peashooter performance.
