Shield

The Shield (a.k.a Normal Shield, Barrier Shield or just Barrier) is a classic power-up item since Sonic the Hedgehog. It is obtained by destroying an item box with a circular symbol on the monitor. It is the first and original of all shield type power-ups.

The power-up itself envelops the playing character in a spherical barrier which protects the wearer from attacks or damage so that the player would not loose collected rings or a life if they are hit without rings. It's colour varies from blue, green and grey depending on what game it is in. Unlike it's sucsessors it does not have any additional abilities to grant to the wearer.
