Unira is an item in Super Smash Flash 2 originated from Clu Clu Land. Once released, it remains as a ball for a short time. After a brief moment, its spikes come out. The only means of moving it is by using powerful attacks that send it flying for a short distance. Depending on how hard somebody hits it and how fast it is moving, it can be a damaging and/or devastating item to be hit by.
