You, as well as your brother, are my hero.

[giddyman]

Which is correct?

(1) You, as well as your brother, are my hero.
(2) You, as well as your brother, are my heroes.

 

[emsr2d2]

Why do you want to construct such an unnatural sentence? Just say "You and your brother are my heroes".

 

[giddyman]

Not only your brother but also you are my hero.
Is this still unnatural?

 

[teechar]

Yes, it's still no good. Use what emsr2d2 suggested.
