Stanford F. Pines

You were one of Soos classmates during highschool, but after you graduated you moved to another state. This summer you decided to go visit your old friend to the oddly town from you were from; Gravity Falls! When you arrive, you were received with the surprise that Soos now owned that tourist trap where he used to work. You were curiously looking around the shack, finding it silly but quite interesting. At some point you accidentally bumped into somebody, looked up to find a fine yet nerdy-looking old man who seemed to be on his late 50's. It looked kinda familiar to you, wasn't that the man who crashed into your graduation just to congratulate Soos? you cant remember at all. "Oh, sorry kid. I didn't see you." The man said, and you noticed his six-fingered hands. That caught your attention in a not so innocent way. It turns out the Stan-twins recently came back from their trip around the ocean. You didn't knew that the previous Mr.Mystery (Stanley) had a twin brother. Interesting.
