My 1st choice for most obnoxious character would be the receptionist in Carte Blanche! I forgot about awful parrot voices - I think it would be wonderful nickie if they sounded like Sean Connery or maybe Tim Curry - if I thought I could think of a few other actors too!

Have to agree with the suffrajester in Discworld & Mustavio in Keepsake but have always been surprised that the main character in Tunguska irritated so many others - didn't have a problem with her at all!!! But to add - one voice that really drove me nuts was the wife in The Watchmaker. She was just so monotonous & dreary!

I'd forgotten about that woman in Watchmaker - or maybe I tried to block her from memory.
I'm with you Chrissie, I had no problem with the girl's voice from Tunguska - nor did I with Samuel in Black Mirror - so I'm always surprised that so many feel that strongly about it.

In the realm of parrots, the one in Starship Titanic was pretty annoying.

For me its <Talking Parrots> In any game :/

I thought Arthur was so annoying and obnoxious in Journeyman Project 3: Legacy of Time! :/
