He led a bridge simulation cadet group, acting as its captain. According to the Starfleet Command School customs, his class kept junior cadets inline in the place of officers. (TOS novel: Starfleet Academy)
He also had an adversarial relationship with David Forester, a junior cadet captain, and made no secret his strong dislike for him. They first met during the opening speech ceremony for the Starfleet Command School where, as a brawny senior cadet]], he threatened Robin Brady unless he moved to the next chair. (TOS novelization: Starfleet Academy)
Malan was part of The Vanguard, a political group that believed the Federation should take a more hard line approach to hostile species, such as the Klingons and Romulans. He was also a racist, going so far as to refer to Vanda M'Giia as "the alien".
Captain Hikaru Sulu sent Malan to the simulator bridge where Forester was assisting Pavel Chekov's neurofeedback resolution reprogramming, and informed Cadet Forester that his team was expected in the Soccer field. (TOS novelization: Starfleet Academy)
During that particular match, Forester performed a "textbook maneuver" of a spin kick to steal the ball, but Frank emerged and tripped his shin. He called his team to gather and gave a speech about how there is more to commanding than the inefficient regulations. Vanda M'Giia and Geoffrey Corin from Forester's team supported him. Shifting the subject to politics, he addressed both teams (and some curious strays) saying that the Federation spends too many resources trying to keep the peace with aggressive and hostile races who don't deserve the tolerance. He mentioned a recent reemergence of Klingon hostilities during the Organian Peace Treaty. (TOS novelization: Starfleet Academy)
In his final year at the academy he and a large number of Vanguard supporters were arrested for attempting to blow up several key federation facilities on Earth. (TOS video game: Starfleet Academy (game))
- If the player decides that Forester should go to the Vanguard with M'Giia, they are the ones who stop the Vanguard together with James T. Kirk and Security officers. If the player decides against it, M'Giia stops the Vanguard on her own.
- The character's name could be derived from Daniel François Malan, the South African Prime Minister who introduced Apartheid.
