I once loaned my cart to a friend, and looked at their save when I got it back. They named Crono “Punk”, I think Lucca was “Glass”, and Magus was “Goth”. Sadly I don’t have the save anymore and I can’t remember the others.

Edit: Also wasn’t there a typo or something when Robo is first introduced? Like R-66Y vs R66-Y? I tried to name him correctly once but messed it up because of that.
