He is voiced by Tex Hammond in Season 3 who also voices Lincoln Loud.
Xuppu is a small monkey-like creature, and he has brown eyes.
Like all kwamis, Xuppu can fly, levitate, phase through solid objects, and carry things that are bigger than him.
Xuppu can transform the holder of his Miraculous into a monkey-themed superhero by going inside their Miraculous.
As a kwami, Xuppu gives the wearer the power of jubilation and transforms them into a monkey-themed superhero by entering the Monkey Miraculous. Although unable to communicate to the wearer while they are transformed, Xuppu usually knows what is going on during that time. Whenever the wearer uses Uproar, Xuppu begins losing power and eventually can't retain the transformation any longer, leaving the circlet and reverting the wearer back to normal. Xuppu is exhausted and out of energy afterwards, so to be able to transform the wearer again, he must refuel by eating food.
Thousands of years prior to the series, Xuppu and the other Kwamis traveled the universe, unable to interact with any creatures, particularly humans. This was until a mage forged the Miraculouses, so Xuppu and the others could both interact with mankind and grant them the ability to transform into heroes; Xuppu and the Monkey Miraculous able to give a person the ability to grant other people superpowers.
