This just exploded my brain. I'm having a moment, lol. Somehow people/Titans can choose which Titan form a person can become. Which would make total sense, as both Colossal and Armored Titans are both built for their missions, seeing as you'd need tough armor and a huge foot to break through two gates. I already thought this may be the case because it's obvious their forms were made for the sole purpose of their assigned roles, but wow, it's interesting how this slipped by me. Good eye.
