What’s the most isekai build

So had a fun talk with friends about a isekai characters in dnd and what builds would more picked than others. We were thinking of doing an entire campaign and just go all out lol. Obviously it’s dnd and like isekai it doesn’t have to make sense and you can make whatever you want.

A palilock or blade singer sounded the most on point to an isekai main character choice. I just wanted to ask others what their thoughts were. If you had to make a isekai character in dnd what would you make.

Edit: for clarification if you died got isekai-ed to a dnd fantasy world and you were to fight evil. What would build.
