Mastering Therian Formes: Essential Guide to Pokemon Go’s Legendary Transformations
Introduction to Therian Formes
Pokemon Go’s Season of Legends marks the mobile debut of the highly anticipated Therian Formes for the Forces of Nature trio: Tornadus, Thundurus, and Landorus. These alternate forms first appeared in the 2012 Nintendo DS titles Pokemon Black 2 and White 2, revolutionizing competitive play with their unique stat distributions.
Unlike their Incarnate Formes seen in the original Black and White games, the Therian variants feature completely rebalanced stats and distinctive visual designs that reflect their elemental natures more accurately. This transformation isn’t merely cosmetic – it fundamentally changes how these Legendaries perform in battle.
The introduction of these formes coincides with Pokemon Go’s new weather-based gameplay mechanics, paying homage to how these creatures originally roamed the Unova region’s overworld in response to atmospheric conditions. Trainers should note that obtaining these powerful variants requires completing Special Research tasks during the three-month Season of Legends event.
Stat Comparison: Therian vs. Incarnate Formes
The Therian transformation dramatically reshapes each Pokemon’s combat capabilities:
Tornadus (Flying-type): Sacrifices 15 Attack/Special Attack for 10 Speed gain, making it an ideal lead Pokemon for fast setup. Its increased defenses (+5 each) help survive initial assaults.
Thundurus (Electric/Flying): Gains 20 Special Attack at the cost of 10 Speed/Attack, transforming it into a devastating special sweeper. Pair with Thunder Wave to mitigate speed reduction.
Landorus (Ground/Flying): Receives 20 Attack boost while losing Special Attack/Speed, creating the ultimate physical wallbreaker. Its new stat spread makes Earthquake and Stone Edge particularly devastating.
Pro Tip: These stat changes mirror their VGC performance – Tornadus for utility, Thundurus for special pressure, and Landorus for raw power. Build your teams accordingly when they hit Pokemon Go.
Competitive Meta Implications
Since their 2012 debut, Therian Formes have consistently ranked among the top threats in official Video Game Championships. Their ability to switch formes via the Reveal Glass item created unpredictable matchups, forcing opponents to prepare for multiple potential stat spreads.
In Pokemon Go, their impact may be even more pronounced due to:
- Limited counter options against maxed Legendaries
- Weather boost mechanics amplifying their strengths
- The current absence of ability-based checks
Common Mistake: Underestimating Landorus-T’s physical bulk. Even with reduced Speed, its Attack stat and typing make it dangerous in late-game scenarios.
How to Obtain Therian Formes
Niantic has confirmed Therian Formes will rotate through five-star raids during the Season of Legends (March-June 2021). Each member of the trio will have a dedicated month:
- March: Tornadus Therian Forme
- April: Thundurus Therian Forme
- May: Landorus Therian Forme
Advanced Strategy: Stock up on Golden Razz Berries and coordinate with local trainers via Discord to maximize your catch chances during their limited availability windows.
