I know almost everyoneâs currently raving about Dipper/Author parallels and honestly they might have stuff in common beyond mystery solving we donât know yet, but the show has made it abundantly clear at this point that there are many similarities that exist between Stan and Dipper. Stan himself has literally told us that he sees a lot of himself in Dipper. Dreamscapers is a whole episode dedicated to this.
[look little Stan even has worry lines around his eyes like Dipdop does]
 Stan was bullied as a kid and Iâm betting Dipâs given a hard time by his peers too (weâve already seen him harassed by Robbie). Both of these guys want/ed to be stronger, and even though they donât like the methods their father figures go about making that happen, its really paid off for them
[Dipâs even punching with this left fist too]
Boyz Crazy is another episode we see obvious parallels. Everyone seems to think Stan was this huge flirty ladies man jumping from crush to crush when he was younger but?? iâm pretty sure Stan has been in love with the same girl since he was a dorky teenager
 a lot like another dorky pre-teen we know
[neither of them really âgetâ their girls either]Â
Dip and Stan are both arrogant and stubborn as hell, and thatâs why I think they butt heads a lot of the time. [âThe kidâs stubborn, thatâs his problem. Sorta like me, I suppose.â]
They like to see themselves as heroes
 And theyâre wildly determined to achieve their goals (to an obsessive degree Iâd say). Theyâre definitely not afraid to get their hands dirty in the process (ie. cheating, lying, and revenge).
At one point Stan yells at Dip 'Your dumb obsession is going to get us all in trouble one of these days!â and heâs rightâDip trying to find the Author and prove himself to the public does get them into troubleâbut its pretty ironic that Stan's nearly identical obsession has gotten them all into major trouble now too.
Grunkle Stan is a pretty selfish, greedy guy, but when it comes to his family heâll drop everything to help and even fight if he has to. The same goes for Dip. Protecting Mabel is pretty much always his first priority. He sacrifices everything for her well-being (mystery solving, his crush on Wendy, his life, etc.) so that sheâs happy, with the exception of Sock Opera which was necessary so that Mabel could realize she hadnât been returning the favor.
[iâm gonna point out in the above photoset, the dialogue Stan says in Scary-Oke is the exact same Dip says at the end of Sock Opera ('everything hurtsâ). not sure about the significance, but TV Tropes has this parallel listed as a 'meaningful echoâ]
Stan might be more âfunâ per se, but heâs much more cynical and practical like Dipper is, compared to Mabelâs eternal optimistic idealism.
Any time she does something silly, Stan and Dip are usually responding with a snarky comment. This pragmatism vs idealism is especially made apparent in Boss Mabel, when Dipperâs about the business and Mabel is about making people happy (which is why she ends up being a terrible boss).
 It seems this fandom just assumes Stan isnât smart, but Iâve never once thought that? Heâs incredibly cunning, clever, witty, and intelligentâa lot like Dipper and Gideon too. Gideon is listed as both Stan and Dipperâs evil counterpart. The personality similarities might explain why these three men are right next to each other on Billâs Wheel, but I digress.
honestly I could go on and on here. thereâs just so many parallels drawn between Stan and Dipper, and as we all know by now nothing in this show is highlighted unless thereâs a reason for it.
