Lord Varios from Shining Force

100% correct! :)
Your turn.

Who is she?

Oh come on...that's too easy. ;o)

Yeah, I know what you mean. Finding (or creating) a good screenshot can be a tedious activity.
There is another thread running ("What's this movie?") where I also know the current answer - but I really don't want to give the solution, again.
Not only do you have to present a screenshot - you also have to think of good hints.
That can feel like work.
Especially since it feels as if only three to five people partake in these forum games at all.
So - if you know a lot of games/movies or are just good at playing detective, it's your turn every other day. :)

It's Elaine Marley. I keep looking on here but have never known one before!

Of course she is. And what a beauty she was! :-)

Your turn, I guess. Officially Cervello has to confirm you're right, but I guess that's a given.

Correct!
Your turn.

Right then, who is this?

My first impression after seeing the screenshot: this looks like it could be some shareware- or advergame.
But I have no clue, really.
Nothing in that picture rings a bell for me. ¯\_(ツ)_/¯

I was just reading the "What is this movie?" thread and thinking you seem to know all of the answers ha ha ha!

If people want a hint, it was based on a cartoon series from the 90s.

Nah,...far from it, really. ;)

Is it Kwame from Captain Planet and the Planeteers??

Sure looks like we have a winner...it's Kwame from the Amiga version of the game, to be precisely.
