The Witcher Season 2: 10 Monsters We Want To See
4. Trolls
Trolls may have only been a brief part of the books - with no explicit appearances - but CD Projekt Red turned them into one of the most endearing creatures in the series. However, their humour doesn't negate the fact that they are a dangerous foe that could crush Geralt within an instant.
In the games, Trolls came along as a sentient and quite advanced species that could comprehend and observe human behaviour but not completely understand it. This led to plenty of great moments thanks to their ability to form sentences and actually communicate with Geralt. There aren't many monsters that he can talk to before taking a sword to them.
Seeing Geralt work with or negotiate with a troll in the show would be comedy gold, and they'd no doubt bring a peculiar cute factor thanks to their loveable ignorance and broken speech pattern. Additionally, the stocky and well-built creatures would look amazing thanks to their variations of type - i.e. ice, rock and regular - and large size.
Viewers definitely need to see a "trollollo" before the season is out.
