Is Default 2d Character Free?

i want to make a 2d game and publish it on the Google Play Store.
But I want to use the Default 2d Character that comes with Unity. Am I allowed to do this, or is the 2d character only a showcase or something like that?

I apreciate any answer.

Yes you are but Google Play will reject your App for having such Free content in it. If you do succeed in publish, the automated systems will kick in removing it in about 2 weeks.
