Watch The Question's appearances in JLU cartoon for inspiration.
in the finale he drove his car through a city filled with Parademons and punched one in the face when it busted through his window and knocked it off.
So I suggest
-a hyper where he runs the opponent over with his car.
-using his disguise gas as a special where he disguises himself, passes by the opponent becomes the Question again and delivers a few blows.
-A strangle/judo throw using his necktie as noose (from where he tried to kill Lex Luthor in JLU)
- His Classic Blank Cards as Projectiles, emitting question mark shaped smoke behind
-Vic Sage is a martial artist, he was trained by Richard Dragon at the request of Lady Shiva.
-Question is also rather ruthless so he should have a more "anti-hero" air about him
so more bone-breaking moves and attacks.
