Headcanon: Damian's Solar Charger
//Had a random idea. Damian is a genius, right? He has even made modifications to his suit and to the Batmobile that have been useful to Bruce. So what if, once he started to really get to know Jon and got kind of attached to him, he started thinking about contingency plans to protect him, as well?
So he creates this device that, during the day, it absorbs the rays of the sun. Then, once activated, it can release that solar energy almost like a diffuser releases essential oils? The idea being, this device can empower a powered-down Kryptonian.
Except Damian wouldn't tell anyone about this device. It would be an extremely closely guarded secret of his - unless and until he might need mechanical help. But when would he ever admit that? Also, it's not an emergency that this thing be up and running as soon as he came up with the idea. It's a "just in case." Anyway, here's the prototype, and Damian has it hidden in a location that no one would think to look, and even if they did, they would still need him (alive) in order to access it.
