In S1-2 he was a guy who is handsome, can fight, is competent at many things and who girls really like, but at the same time a shy nerd with no gf. IE a completely unrealistic character that nerds often imagine themselves as.
In S3-4 he was whatever the people writing any given episodes wanted him to be, ranging from pathetic cuck to literal alpha male, because S3-4 lacked any sense, structure and just basic writing sensibility.
