Like the other Mane6 Next Gens, Harrison got a pretty big make-over. Most notably I changed up his color pallette. He originally looked a lot like Pokey Pierce but I decided to go the other way. His coat looks more like Limestone Pie’s and his mane is somewhat like Maud’s. Add the curly hair and rock farm strength and you have a Pie family member. The only thing Pokey about him is his eyes.
Personality wise Harrison is pretty calm, esecially in comparison to his mom and step-dad and sister. He’s quiet and patient and a very good listener. despite appearing monotone, there’s no way Harry would ever turn down a chance to sing and dance with family or friends. He loves to do karaoke or to sing with the radio. Rock Ballads are his fave.
Igneous Rock and Cloudy Quartz are very proud to have Harrison as a grandson, no matter how he came about. They absolutely refuse to mention his real father and if anypony brings it up, they insist that Cheese is his father and he is a Pie. End of discussion. Harry also loves his aunts, especially Limestone. Nopony really knows why the two just click really well.
Niether Harrison nor Panini have had much contact with Cheese’s mother. She met them when they were both very young but not much other than that.
