Mega Venusaur trades offensive power for exceptional durability. Thick Fat halves Fire and Ice damage — two of the most common attack types in doubles — and since Venusaur already resists Water and Grass, the result is a Pokémon with almost no exploitable defensive hole.
In Sun weather, Fire moves are boosted by 1.5×. Normally this makes Grass-type Pokémon extremely vulnerable in Sun. Mega Venusaur is the rare exception: Thick Fat still halves that boosted Fire damage, letting it operate comfortably against Sun teams that would threaten most other Grass types.
Offensive role
Mega Venusaur’s main damage tools are Giga Drain (heals while dealing Grass damage) and Sludge Bomb (Poison coverage with 30% poison chance). Earthquake provides Ground coverage that handles Steel and Poison types. At 122 base Special Attack it’s a grinding threat rather than a one-hit attacker.
