Clu Clu Land seriesIn Clu Clu Land, the Unira had stolen the golden Ingots from the kingdom Clu Clu Land and buried them in the sea floor. Bubbles the Bubblefish set out to retrieve the treasure, which the Uniras did everything they could to protect. Bubbles would get hurt when she touched the spiky Unira, but she was able to send out sound waves that stunned them, shown by a yellow color. When stunned, Bubbles would run into them and push them into a wall to kill them. New Uniras would appear out from the Black Hole, when the previous ones were killed. Uniras can't pass through uncovered Ingots, which means that they can be trapped if Bubbles turns the Ingots at the right time.
In the sequel Clu Clu Land: Welcome to New Cluclu Land, a game only released in Japan for the Famicom Disk System, there was a new type of Unira called the Boss Unira. Boss Unira appears out of the Black Hole when Bubbles has killed seven normal Uniras. Apart from their size they behave just like normal Uniras. One sound wave is enough to stun them, and then they can be squished against the wall. The look slightly different from their smaller counterparts, as they only have one eye.
Super Smash Bros. series
In Super Smash Bros. Brawl, the Unira is an item. When thrown the Unira's spikes pop out and does damage to whomever who touches it.
The following is Unira's trophy description in Super Smash Bros. Brawl:
- "In Clu Clu Land, the Unira hid gold ingots in an underwater maze, then tried to stop Bubbles from getting them. In Super Smash Bros. Brawl, you can attack a Unira to send it bouncing away. Any fighter it hits will go sprawling. If it hits a wall, it'll bounce back, and if you hit it with a powerful attack, it will transfer the attack to whomever it hits and launch them."
