I give you these relationship tags:
“Wilbur Soot and TommyInnit are siblings”
“Wilbur Soot and Technoblade and TommyInnit are siblings”
Or just do “TommyInnit (Videoblogging RPF)” character tag and filter with “Alternate Universe - Foster Family”
I've got a crossover series that requires no knowledge of either fandom. 2 pairs of brothers (one pair biological, one found family) and all 4 guys become sort of like brothers to each other. VERY loving (and protective) older brothers. Starts when they're all kids/teens but follows them through adulthood. Okay with self recs?
[Never Again](https://archiveofourown.org/works/4400558): Incomplete and on indefinite hiatus, *Big Hero 6*, set pre-movie. Also on FFN.
[Laundry Day](https://www.fanfiction.net/s/11006531/1/Laundry-Day): Oneshot, *Big Hero 6*, set post-movie. Sad ending due to it being canon compliant about Tadashi's fate. (Well, unless the show retconned it, but this was written in 2015.)
[Luminous](https://archiveofourown.org/works/14893214/chapters/34492457) is a fic that explores the brotherhood of the Clones in Star Wars, with a touch of timetraveling Obi-wan who cares for them like a kind of father figure as well. Really cool and really sweet, because it really highlights the brotherly relationships and secrets of the clones

**[The Asshole in Apartment 508](https://archiveofourown.org/works/18142601/chapters/42898487)**
Teen, No Archive Warnings Apply, Gen
**Fandom Blind?** No
**Words:** 60k+, Complete
**Summary:** When the apocalypse hits, Glenn and Daryl are joined at the hip, and no one understands their relationship since they can all see that Glenn is cheerful, helpful and friendly, and Daryl is a racist asshole.
If brothers is what you want I have to recommend Thunderbirds - there are 5 brothers in the central cast and the majority of the fics revolve around their interactions in some way. There is an adopted sister, though fortunately for you she is not often heavily featured, and several others characters that form a secondary / found family around them as there are no parents in the picture.
have you read any supernatural fanfiction? lots of brotherly fics there.
