I'm new to this forum and haven't read the whole thread, so correct me if I'm wrong, but I've read several places that the game has 16 opponents, not 13.
Given this, it all fits. There would be:
- Four circuits with four opponents each a la Super Punch-Out!!
- All ten characters from the original Punch-Out!!
- Five characters from Super Punch-Out!! (Considering Bald Bull, Mr. Sandman, and Super Macho Man to be Punch-Out!! characters, not Super Punch-Out Characters.
- A final boss not in any of the four circuits, possibly Mr. Dream.
We already have Bear Hugger and Aran Ryan confirmed, so the final roster would look like this:
Aran Ryan
Bald Bull
Bear Hugger
Disco Kid
Don Flamenco
Glass Joe
Great Tiger
King Hippo
Mr. Sandman
Piston Hondo
Soda Popinski
Super Macho Man
Von Kaiser
??? (Super Punch-Out!! Character)
??? (Super Punch-Out!! Character)
??? (Super Punch-Out!! Character)
Mr. Dream
The Super Punch-Out!! roster, not including the opponents already listed above, looks like this:
Gabby Jay - Profoundly unpopular, made redundant by the presence of Glass Joe.
Piston Hurricane - Made redundant by the presence of Piston Honda.
Bob Charlie - Bland and unpopular, but perhaps they want some Jamaican flavor? Could be updated.
Dragon Chan - The obvious choice. The most popular character from Super Punch-Out!!, and the most commonly referenced.
Masked Muscle - The spitting made some purists mad, but the character is colorful, and provides an opportunity to play with Mexican stereotypes in a lighthearted way, like what they're doing with the French Glass Joe and the Japanese Piston Hondo.
Heike Kagero - Presence is unlikely, given that the game already has the Japanese Piston Hondo, but possibility of a more proper execution of the bishōnen concept is intriguing, as opposed to the creepy transvestite they made him the first time.
Mad Clown - Colorful but unpopular. The addition of another obese character seems unlikely.
Narcis Prince - Sort of unmemorable, but so is Aran Ryan. He seems to fit in the new roster better than most of the other Super Punch-Out!! opponents, though it might be redundant to have two characters absorbed with their personal appearance in Don Flamenco and Narcis Prince.
Hoy Quarlow - Use of the staff angered most original Punch-Out!! players, doesn't seem to fit in with the roster.
Assuming my interpretation of the information is correct, I'd say Dragon Chan is just about a given, but I'm stumped on the other two. I think we can safely rule out Gabby Jay, Piston Hurricane, Hoy Quarlow, so the remaining two could come from Bob Charlie, Masked Muscle, Heike Kagero, Mad Clown, and Narcis Prince.
