>>56026705He means just a "hello world" character introduction, I think.
>>56026686A fair concern. I would say it really depends on what you intend to do with that character. I would say give a character bio that fits within the usual 2000 character post limit. Who they are, what they're about, what kind of team they use, and maybe a story hook or two you can branch out from to really sell us on the character's identity.
Ignore smogon posters, ignore grumpy ex-girlfriends. They're our heel personalities and they take kayfabe very seriously.
