Love all these charpteeth characters you're showin here already, Hiruma and these kids look epic! & crocodile smiling ones are always a win for me XD
The G-MAN is always a fave, tho he not a human per say.
Even as Shin Godzilla he look like he smiling at ya
Ryuk too
Planning for one of the big badguys later in m\my current series to have a mouth with creepy sharp teeth, tho haven't drawn him yet.
This old Oc from an old Fighting Game Idea I had got the sharp smile -mysterious humanoid demon who causes mischief poses as a child and uses snot as a projectile.
The Main Antagonist from same fighting game idea had em too The Lord Enforcer - though you may not see em from the distance (this guy sorta influenced/ evolved into some of the characters in SickBoy, current series)
Bonus :
Baraka and Mileena aren't my faves in MK but their teeth always crack me up
