Unbreakable Container

The Unbreakable Container (ブラックコンテナ) is an object that appears in the Sonic the Hedgehog series. It is a type of heavy Container that can be found in various levels throughout the Sonic series. As it name implies, it is virtually unbreakable, making it both a sturdy obstacle and an in-level object.

Description
The Unbreakable Containers possess a simple, cubic-shaped design. Although their superficial appearance has varied since their introduction in Sonic Adventure 2, they are typically made of heavy metal. In gameplay, the Unbreakable Containers are some of the most basic of all Containers. Their widest known quality however, is that they are completely unbreakable (except in one instance), meaning they are resistant to gimmicks and the playable characters' attacks. They are similarly immovable under any circumstances (with the only exception being in Sonic Adventure 2). Due to their sturdiness and immovability, they are essentially parts of the levels themselves.

Unbreakable Containers typically serve as obstructions that the player will encounter along the paths in the various levels, and are mostly set on the bottom of Container stacks. They mostly lie on the ground, typically along walls and edges. They can also lie around in different formations that take the form of walls, pillars or rows that the player has to get around. In other cases, the Unbreakable Containers has been used as stepping stones or stairs to reach higher areas. In other instances, the Unbreakable Containers have even been used as building blocks to construct paths, floating platforms and walls, and passageways in the different levels.

Sonic Adventure 2
The Unbreakable Containers made their first appearance in Sonic Adventure 2 and its remake Sonic Adventure 2: Battle where they serve as major gameplay objects. In this game, they are dark gray-colored with an X-shaped mark and a GUN logo on each side. In stages where Badniks are the primary enemies instead of GUN robots, however, they have an Eggman Empire symbol on them instead of a GUN logo.

Unbreakable Containers are commonly placed in rows or other formations, and appear in every stage. While immovable in most stages, the player can affect the Unbreakable Containers in Crazy Gadget with the Gravity Control Switch; when that switch is flipped, it will change the direction of the gravity, causing the Unbreakable Containers to fall in the direction of the gravity.

Sonic Heroes
In Sonic Heroes, the Unbreakable Containers were made more colorful in appearance. In this game, they are dark blue metal crates with red segments on their edges, an X-shaped mark on each surface, and a white symbol depicting a five-pointed star on each side.

In gameplay, it is possible to destroy the Unbreakable Containers by firing the playable characters directly into them with the Cannon. Aside from that, however, they are completely unaffected by gimmicks and attacks. Because they usually block pathways, the Unbreakable Containers are often stacked in two-boxed towers, sometimes with different types of Containers added to their mix.

Shadow the Hedgehog
In Shadow the Hedgehog, the Unbreakable Containers are more diverse. In this game, they retain their metallic composition and the X-shaped mark on each side. However, their logo and coloration vary. Depending on the Stage they are in, Unbreakable Containers are either colored yellow, grey and red with the Eggman Empire logo on it, or grey and brown with the GUN logo on them.

Other than the serving their standard purposes, the Unbreakable Containers play no special roles in Shadow the Hedgehog.

Sonic Rivals 2
In Sonic Rivals 2, the Unbreakable Container is featured as one of the collectible cards in the game. This card in particular depicts its appearance from Sonic Adventure 2. To collect it, the player has to successfully use one hundred Power-Ups in gameplay.

Sonic Colors
In the Wii version of Sonic Colors, the Unbreakable Containers made a reappearance in gameplay. In this game, they are dark gray metal crates with an X-shape mark on each surface, light blue-glowing corners, and no hallmarks on them.

In gameplay, in addition to serving the same purposes they always had, the Unbreakable Containers are also used as building blocks to construct walls, floors and ceilings in various Acts. In some cases, the Unbreakable Containers even float in midair while retaining their immovability.

Sonic Generations
In the console/PC version of Sonic Generations, the Unbreakable Containers appeared in gameplay once more. In this game, they are black metal crates with an X-shape mark on each surface and no hallmarks on them.

In gameplay, the Unbreakable Containers serve their traditional purposes. In this game however, they exhibit special properties: they can fill up the Boost Gauge should Modern Sonic collide with them at high speed or through a Jump Dash. In the latter case, a Jump Dash executed on an Unbreakable Container will turn into a Homing Attack, and Sonic will do his regular animation then. Sometimes, when hitting an Unbreakable Container at a certain point, a friction-like light will emit as if Sonic is kicking it.

Sonic Forces
In Sonic Forces, the Unbreakable Containers made a new reappearance in gameplay. In this game, they are black metal crates with an X-shape mark on each surface and no hallmarks on them.

In gameplay, in addition to serving their traditional purposes, the Unbreakable Containers are also used as building blocks to construct entire tunnels and level segments throughout the various stages. Like in Sonic Colors, some of the Unbreakable Containers even float in midair while retaining their immovability.
