These characters will be returning in Suikoden 2. Many thanks to New Jack for this information!
Returning as Stars of Destiny:
Valeria/Kasumi (You have to choose)
Vincent de Boule
Returning in Cameo Roles:
Gremio (if you revived him and loaded Suikoden 1 data)
McDohl (except, now the first letter of his name is dependant on what you named him in the original.)
The Hero from the original Suikoden can appear in the game if you load data from Suikoden 1 saved at the end of the game (before heading into Gregminster) with Gremio revived. He joins your army, but is not one of the Stars of Destiny (there are six others like this.) After recruiting McDohl, you can use him in your party any time you want, except you have to return to Gregminster each time you want him in your party. It's pretty cool to see the reactions of returning characters when you first meet him. The Suikoden 1 data can be loaded when you first start a game of Suikoden 2, but if you have no old data, McDohl and Gremio will not appear in the game at all.
