Forretress Forretress Playthrough, Competitive, and Nuzlocke Usage
Using Forretress in a Playthrough
The Pineco line develops into Forretress, a slow Bug/Steel Pokemon whose value comes from extraordinary physical Defense, numerous resistances, and utility rather than sweeping power. Pineco evolves at level 31, after which Forretress reaches base 140 Defense and gains Steel typing, leaving Fire as its only conventional weakness but making that weakness quadruple. Its base 90 Attack is usable with moves such as Gyro Ball, Payback, Earthquake, or Bug STAB depending on generation, but Forretress is usually more valuable for support through Spikes, Toxic Spikes, Stealth Rock, Rapid Spin, screens, or later Volt Switch. Its extremely low Speed can actually strengthen Gyro Ball and makes slow Volt Switch useful for bringing a teammate into battle safely after Forretress absorbs an attack. The main story limitation is poor Special Defense: Forretress can shrug off many physical hits but strong special attacks, especially Fire moves, can overwhelm it quickly.
Forretress in Competitive Pokémon
Forretress has one of the strongest historical competitive resumes among defensive Johto Pokemon because it repeatedly compressed entry-hazard setting and hazard removal into a single team slot. It was already an OU Pokemon in Generation II, where excellent Bug/Steel typing, base 140 Defense, Spikes, and Rapid Spin gave it an important role in a metagame where Spikes heavily shaped switching. Its importance continued through ADV and DPP, with DPP Forretress notable for access to Rapid Spin alongside Spikes and Toxic Spikes, while later generations added Stealth Rock, Volt Switch, and the modern form of Sturdy to expand its utility. Its weaknesses have remained equally consistent: poor Special Defense, extreme vulnerability to Fire, lack of reliable recovery, and passivity can allow dangerous setup sweepers or special attackers to exploit it. Even so, Forretress has repeatedly remained relevant because very few Pokemon can match its combination of physical bulk, hazard control, hazard stacking, and defensive typing.
Forretress in Nuzlockes
Forretress can be an excellent Nuzlocke defensive Pokemon because its enormous physical Defense and Bug/Steel typing allow it to switch safely into a wide range of predictable physical attacks. Its many resistances and Poison immunity make it especially useful for controlling physical opponents, while later Sturdy can guarantee survival from full HP against a single ordinary attack and create an emergency opportunity to retaliate, set support, or switch. The danger is its quadruple Fire weakness combined with only base 60 Special Defense, meaning even unexpected Fire coverage from a Pokemon that Forretress otherwise walls can cause an immediate loss. Pineco and Forretress are also associated with Self-Destruct and Explosion in several games, so wild encounters can themselves be dangerous, while using those moves on a trained team member is normally incompatible with preserving it in a Nuzlocke. Forretress is therefore safest when the opponent's special coverage is known and it can be used as a deliberate physical wall rather than a universal tank.

When something approaches it, it fires off fragments of its steel shell in attack. This is not a conscious action but a conditioned reflex.
In the moment that it gulps down its prey, the inside of its shell is exposed, but to this day, no one has ever seen that sight.

Forretress Biology and Behavior
Forretress encloses itself inside an exceptionally hard steel shell and attaches itself almost immovably to tree trunks in temperate and tropical forests. It opens the shell only briefly to capture prey, snapping it shut so quickly that observers have never clearly established what the rest of its body looks like inside the armor. When threatened, pieces of its outer shell can be fired outward as a defensive reflex rather than as a carefully aimed conscious attack. Despite its heavy armored appearance and lack of visible limbs, modern observations show that Forretress is capable of levitating above the ground. Its hidden interior remains one of the more persistent anatomical mysteries among otherwise well-documented Pokemon species.

Forretress Size Comparison: BETA
Forretress is listed at 3' 11" (1.2 m) and shown in an in-chart visual comparison.

How is visual size determined?
Pokédex height is treated as the official listed measurement, but the chart uses pose-aware visual scaling so each sprite looks reasonable in a direct comparison.
For long or coiled Pokémon, the listed height may represent total body length rather than upright height. For Pokémon with floppy ears, leaves, feathers, antennae, wings, or other flexible features, the chart usually measures to the top of the solid, substantial part of the head or body instead of the tallest decorative feature.
The goal is not to replace the official height, but to make the artwork compare naturally at the size it appears to occupy.
