In Combat, Dr. Kavan behaves like Medics, healing troops in his small area of effect but is unable to defend himself.
As a Hero, he does not require time or Gold to train. If he is defeated in battle, he will reappear in the Hero Hut after the battle, fully healed and ready to fight again.
His Hero Perk is Galvanizing Presence, which slightly reduces incoming damage of troops he heals for a short period of time.
