The Ring Portal is an Item Box power-up that appears in the Sonic the Hedgehog series. It is a Boost Item used primarily to increase the user's speed.
Description
The Ring Portal's icon takes the form of a giant golden Ring with a shimmering center. In gameplay, this power-up creates a portal the user passes through, which turns them invisible for a while sparkles surround them until they emerge from the portal again.
In gameplay, the Ring Portal can only be obtained at random from Item Boxes by Teen Sonic.
Once obtained, the player can utilize the Ring Portal by pressing its icon on the bottom of the HUD. When used, the Ring Portal will increase the speed of the user for a short amount of time. In addition, while the Ring Portal is active, the user becomes invisible and invulnerable to most obstacles and offensive power-ups from rivals, but they are still susceptible to falling into bottomless pits. The user can also still destroy Badniks and collect Rings while using the Ring Portal, though they cannot pick up new Item Boxes. The duration of the Ring Portal is shown by the decreasing gauge on top of this power-up's icon on the bottom of the HUD whenever the Ring Portal is in effect.
The Ring Portal can also be upgraded by leveling the user up to level 2, 8 and 14 respectively. For each upgrade, the Ring Portal will last longer.
Trivia
While the Ring Portal's design and main ability are based on the Giant Ring, it also takes after the usage of Rings in the Sonic the Hedgehog film series.
