He reminds me of Trelane...just a little *lol*

I'd say all of these depending on his mood, but I think that even fighting against a villain people will learn a lot.

More of a teacher more so in the novels.

Sometimes he tries to be a teacher or helper and it just ends up causing chaos, and sometimes he says he's villian but, we all have our doubts.

He's not a villain, but a tough teacher in both the series and novels. makintosh and legodogs are not bothering to use any facts to back that up.

Q Who?
"Maybe Q did the right thing for the wrong reason."

"How so?"

"Well, perhaps what we most needed was a kick in our complacency, to prepare us ready for what lies ahead."

Tapestry
"And, you know, there's still a part of me that cannot accept that Q would give me a second chance, or that he would demonstrate so much compassion. And if it was Q, I owe him a debt of gratitude."

"In what sense? It sounds like he put you through hell."

"There are many parts of my youth that I'm not proud of. There were loose threads, untidy parts of me that I would like to remove. But when I pulled on one of those threads it unraveled the tapestry of my life."

All Good Things
"You just don't get it, do you, Jean-Luc? The trial never ends. We wanted to see if you had the ability to expand your mind and your horizons. And for one brief moment, you did."

"When I realized the paradox."

"Exactly. For that one fraction of a second, you were open to options you had never considered. That is the exploration that awaits you. Not mapping stars and studying nebulae, but charting the unknowable possibilities of existence."

"Q, what is it that you're trying to tell me?"

"You'll find out. In any case, I'll be watching. And if you're very lucky, I'll drop by to say hello from time to time. See you out there."
