I never read Traveller, so that'll be for tonight!
Read a few fics recently, will post here. Going to dig around. These aren't all the highest of quality, but I enjoyed them decently

Time travel/memory loss: Fanfic about memory wiped time traveller from some war era in the future who is Ash's age and ends up joining their group. It's basically an episode by episode retake with the female character added in. There are only some small changes from the original canon, but they add a nice touch without messing the existing up too much. I had fun with it since I didn't remember the original series and used it as an excuse to watch some season 1 episodes.

Isekai: Man transmigrates into body of kid, spends X filler years before turning 13 the age to get a starter (and is also a few years older than ash/gary). Immediately goes on adventure that gets sidetracked into some Blackthorn clan parent assassination plot before it was dropped.

Isekai: MC isekais into tree of beginning, turned into a 10 year old and gets aura powers, immediately becomes an aura guardian knight and spends his time criticizing ash and power tripping. Would have been more enjoyable if it was longer and fleshed out, but it's just 16 chapters and dropped so judge it yourself.
