Some larger MEGA Pokémon sets include crank-activated movement — for example, an Eevee set runs when you turn a crank and a Charizard set uses a crank to move its wings.
Several MEGA Pokémon sets state that their bricks combine with other MEGA building sets and are compatible with other name-brand building bricks.
The pieces are plastic, and multiple product details explicitly state "Battery: No Battery Used," so most sets do not require batteries.
Some Pikachu sets list articulated, poseable parts — ears, arms, legs and tail are described as movable so the finished models can be positioned in different stances.
Some sets include extra buildable figures and accessories. One set lists four buildable Pokémon (Pikachu, Squirtle, Charmander and Bulbasaur) plus buildable environment stands, while other sets list a single included figure or blocks.
Difficulty varies by set: some larger motion and jumbo sets are described as "challenging" and target adult collectors or experienced builders, while other sets list lower suggested ages and may require help from an adult for younger builders.
Many sets are presented as display pieces or centerpieces; a few specifically include display features such as a flat base and a notch for wall mounting or are described as suitable for shelf or desk display.
