Invincible^[1] (無敵^[2], Muteki^?), also called Invincibility,^[3] is an item box power-up that appears in the Sonic the Hedgehog series. When the player obtains this power-up, the playable character becomes immune to most damage-causing hazards for a short period of time.

Since its introduction, Invincible has become one of the most recurring Item Box power-ups in the Sonic series. The effects of Invincible have as well remained mostly untouched, like the Super Rings and Power Sneakers. In several games though, it has possessed different features.

While Invincible has not been as generally featured as it was in the earlier Sonic games, it is occasionally used in the latest entries as well, mostly appearing in 2D titles as well as 3D games that do not make use of the Boost mechanic.

Description[]

Item Boxes containing Invincible usually either contain or display an icon depicting four-pointed white stars or a colorful, sparkling shield. When the player obtains Invincible, the playable character can destroy or damage enemies upon physical contact, even when not attacking. In addition, the playable character cannot take damage when touching enemies and obstacles. This allows, for example, the playable character to walk on spikes without any ill effects. However, the player can still lose a life should they get crushed under objects, drown underwater, fall into a bottomless pit or get a Time Over. Also, whilst Invincible is in effect, the background music for the level changes to a dynamic-sounding theme or fanfare, which is usually either a rendition of the game's main theme, or another track exclusive to Invincible.

Invincible usually lasts about 15–20 seconds before it fades out, though the length of Invincible can differ between certain games; breaking another Invincible Item Box while already under its effects can prolong the status and sometimes reset the fanfare related to this power-up as well. After the time runs out, Invincible will disappear and the player becomes vulnerable once more.

When using Invincible, the playable character gets surrounded by a sparkling effect, which is used metaphorically to show when Invincible is in effect. The visual aura effects from Invincible vary in appearance from game to game; in some games, like the 2D games from the Sega Genesis/Mega Drive era, the player is surrounded by a cloak made up of countless sparkling white stars. In other games, like in 3D games such as Sonic Adventure, Invincible's visual effects tend to take the form of a sparkling rainbow aura. Also, in Sonic Heroes, Invincible's effects around the player are glowing lines.

Invincible was a fairly common power-up in the early Sonic games, but it has since become rarer in later installments in the series. In later games, modern-styled Item Boxes containing Invincible are blue-colored instead of the usual red to distinguish this power-up from more common ones.

Super transformations of playable characters usually grant invincibility (alongside the effect of Power Sneakers in 2D games) during normal gameplay, though it only lasts for as long as the transformation can be maintained, which is tied to the Ring count that decreases one every second while in a Super State. Usually, Super State users can only be briefly stunned by some of the bosses' attacks, but in few games, more powerful attacks are able to bypass the invincibility, and damage the playable character in their Super States and greatly decrease the Ring count.

Trivia[]

• The Invincible theme from the original Sonic the Hedgehog has been the most reused one through the Sonic the Hedgehog series.
• In Sonic 3 & Knuckles, as well as Knuckles in Sonic 2, due to Sonic and Knuckles sharing different color palettes, the stars created by Invincible have red coloration instead of blue when the playable character is Knuckles. The Aqua Shield and S power-ups both share this trait, in the case of the former.
• An early version of the Sonic Superstars Invincible theme exists, with Sonic 4-like instrumentation, and it sounds different from the final version.
• In Sonic Rush, there is an invincibility music glitch in Dead Line, sometimes some PCM channels will be isolated if Sonic uses the boost and Humming Top trick too fast.
  • The same goes for Sonic Rush Adventure where the Hidden Island Invincible music will just isolate all of the PCM channels except the percussion channel unless Sonic goes too fast with the boost. Sometimes a few of the PCM channels will isolate too.
