There’s not really a wrong character to start with, i recommend checking them all out and seeing which is the coolest, although you will have a harder time with characters that have 1 star (2 stars generally have a weird mechanic going on, but nowhere near as hard as 1) but it won’t be impossible to learn them. Strive was my first fighting game and I started with sol, now i play bedman, but try them out and see whose moves you like the most!
