Tiny ideas (Titans)
Titans probably get struck by lightning a lot because they're so tall. Might their designers have taken this into account and enabled them to charge up from this?
How did the Titans learn to fly? Were they already pilots before they got upgraded to Titans? How would being a pilot compare to actually being the flying thing?
Titan Camera uses sodium-based batteries rather than lithium-based, because of the lesser fire risk (an important consideration when your flagship weapon is making fire come out of your tits).
