Defeated with Tokugawa Yoshinobu, 15th and last shogun of Japan.
Akinator does better with European and US names, I think.
Who is Lloyd Mangram?
Some schmuck?
I stumped it with Swee Pea, from Popeye? That’s crazy.
I guess that a lot of guesses depend of how well the guy answering knows the character. In this case I answered “partially” to the questions about it being from a cartoon. I guess many people don’t know about Segar and just answer “yes”.
Come to think about it, it took him ages to guess Wonder Woman. Maybe a lot of people just answered “yes” to “Is your character American”?
Holy cow! He guessed Sam Temple from the “Gone” series at the first try!
Again, probably a case of there being only one clear source for the character’s narrative.
So Akinator may be better at obscure characters with limited information about them.
Took 2 levels, but he got Wesley Dodd, the Sandman.
The best I did was 30 questions (and one failed guess) with Max from the old Mighty Max cartoon.
I stumped it four times (legit ones, not ones where name was already in the database): Jack Marshak of Friday the 13th, the Series, the NPC Kromede of the MMO Aion, Amos of Dragon Quest VI, and Sir Henry Merrivale, the John Dickson Carr detective.
Nothing beats that sinking feeling you get when he starts asking questions pretty specific to OTHER characters in the same work you got yours from. 
It got Melisandre from A Song of Ice and Fire so I went much more obscure and stumped it with Oliver from the Chanson de Roland, which I’m reading for a class.
Or maybe they knew about Segar, and therefore answered “yes” to being from a cartoon. Specifically, the cartoons Segar drew. Unless it specifically asked about animated cartoons?
But yeah, I seem to draw finer distinctions on those things than other answerers do. I’ll only answer that a character is from an animated cartoon, or from a TV show, or from a movie, if that was the source of the character. This is as opposed to “Did you character ever appear in a movie?”, or the like. So for instance, if I’m thinking Aragorn, I’d answer “no” to “Is your character from a movie?”, but “yes” to “Has your character ever been in a movie?”.
It got Jed Bartlett with ease. I knew it was going to guess right when one of the questions was “Has your character been President of the United States?”
I managed to beat the akinator with Ryan Tomlin (www.youtube.com/itsryanhere) and it kept suggesting ksi.
I also just beat it with Ty Pennington from extreme makeover home edition I’m pretty chuffed with that lol twice in one evening 
I just beat it with Anomander Rake from the Mazalan Books, came pretty close, suggested Trull Sengar but it had to admit defeat.
I beat it with Dr. Simon Finch-Royce, the marriage expert played by John Cleese on Cheers. Is it cheating to use a character that only appeared once?
I tried “a zombie,” but Akinator guessed it pretty quickly. 
I tried Robert Sheckley. It guessed Hunter S. Thompson, Ray Bradbury, and Michael Crichton. Sheckley was at least in the data this time.
It repeated questions several times, making for tedium. I didn’t bother trying again.
It took it two tries to get Morgan of Hed.
It took two tries to get Billy Ray Valentine (Trading Places).
I beat it with Archie Leach (A Fish Called Wanda, John Cleese’s character).
I saw this kind of thing when it was called “Dictator or Sitcom character” (quite a long time ago in Internet terms), but it’s still pretty addictive. It got Ted Mosby quite quickly
Well, so far it’s gotten Mrs. Brisby from The Secret of NIMH, Oliver Cromwell, and Nero Wolfe from me…
