A Unira is an item in Super Smash Bros Brawl. It can be picked up and thrown at enemies. When it lands its spikes get longer damaging any opponents (except the player who threw it) who touch it. Uniras at first look like blue, small spiked balls. When they land they look more like a sea urchin with an angry face! When the Unira is hit its spikes return back to normal (blue small spiked balls), ready to be thrown again. Uniras don't really KO opponents but it also depends on where you put it.
