Are they waterproof or will water make them malfunction?

He's pretty old, and I think he would actually malfunction D:

What if he was stuck by lightning? Will that overload his system?

Then he'd be all super powered, and have unnatural strength!
Or maybe he'd just short circuit, but he's be okay after a while owo)a

I assume it's similar if he was given a logic paradox. Is he affected by those?

I don't know what that is, haha.

Lol. A paradox is a statement that, despite apparently sound reasoning from true premises, leads to a self-contradictory or a logically unacceptable conclusion. ... Some logical paradoxes are known to be invalid arguments but are still valuable in promoting critical thinking. Robots have purely logical minds. Would he be able to handle one without malfunctioning or would he not be able to handle one?
