The Tornado Boost is a Tag Action in Sonic the Hedgehog 4: Episode II which allows Sonic's biplane, the Tornado spin horizontally while boosting forward.
It is used in Sky Fortress Zone, Act 1 to break yellow boxes that have Dr. Eggman's emblem on them and it is mandatory for the final hit against the Metal Carrier in the Sky Fortress Zone Boss Act.
- This is the only Tag Action move that does not disable Super Sonic when in use.
- After performing the Tag Action, a small star will spin around Tails' head, indicating he's dizzy. This makes you unable to use the Tag Action until the stars disappear.
- This animation does not occur whilst performing the move in a high speed section.
