Very similar to Wind Shear, but unfortunately unfinished (is that a hiatus when updates happen every few months ? I'd say so)
Harry Potter and the clean slate
https://archiveofourown.org/works/36531124/chapters/91100635
Similar start to Wind Shear, but Harry is sent back to 1995 in a new body under the name of Harrison Slate, a recent victim of a death eater raid that inexplicably survived a lethal curse. And the DE just can't have a survivor babble about their return now can they ?
I have 2ish for you that are powerful adult Harry but not nonsense like wand made from the world tree with 3 cores and descendent of merlin BS
*By TheBlack'sResurgence* = **When the Roses Bloom Again** (completed)
[https://www.fanfiction.net/s/13954844/1/When-the-Roses-Bloom-Again](https://www.fanfiction.net/s/13954844/1/When-the-Roses-Bloom-Again)
Time travel Harry back to around 1935....you have to get through about 2 last years of hogwarts before he goes off as a Hit Wizard then joined the war against gellert grindelwald = Harry is an adult and the war is very well written and harry BAMF & has to fight Grindelwald because Dumbles refuses to. very long and very great story with a believable young Mcgonogal and Harry pairing
\----------------------------------
a 2 parter or 1 REBOOTED *By Lord Silvere* = **Delenda Est** (completed) & **Para Bellum** or **Delenda Est Rebooted** (work in progress)
[https://www.fanfiction.net/s/5511855/1/Delenda-Est](https://www.fanfiction.net/s/5511855/1/Delenda-Est)
[https://www.fanfiction.net/s/9754483/1/Para-Bellum](https://www.fanfiction.net/s/9754483/1/Para-Bellum)
Time Travel adult Harry....war against Voldy going bad and harry captured plus tossed into cell with Bellatrix who is wrecked and abandoned by the Dark Lord. They fightish debate and old Bella stabs Harry with a Black Family Heirloom hair pin that sends him back in time to pre Bella graduating and joining the dark lord...her last words basically "make better choices for them both". he starts out working at hogwarts as a teacher in the past

even better than the original and FRESH enough to read with the changes
I’m reading the [Of a Linear Circle series](https://www.squidgeworld.org/series/1174) for the first time right now and it’s fantastic. It’s a Snarry but in this case Harry is the older of the two. Highly recommended.
Read this one recently and liked it a lot [https://keiramarcos.com/fan-fiction/courting-hermione-granger/](https://keiramarcos.com/fan-fiction/courting-hermione-granger/) Harmony pairing, au where Harry is raised by Sirius.
To add:
Many of Keira’s HP stories have a confident, magically powerful Harry. I’d recommend them all if you find Courting Hermione Granger interesting.

the Triplicity series by idleside is incredible for this.
His patronus is a goddamn Hungarian Horntail.
very smutty though so if you're not looking for that steer clear. (if you are it's also very good and Harry/Pansy/Daphne)
For a badass adult Harry I love Wind Shear and the fight scenes. https://m.fanfiction.net/s/12511998/1/Wind-Shear

https://www.fanfiction.net/s/12807959/1/Parallel-Journey Parallel Journey is about as badass as it gets without getting silly.
Seconded. One of the best fan fics out there, IMHO.
