23. Monster-Ock (Spider-Man)
https://www.youtube.com/watch?v=BEmcLg1QEWc For the gamers who played this utterly fantastic Spider-Man game back in 2000, it likely brings back fond memories of feeling like you could actually be the web-head and live in his colourful world of adventure. But perhaps something they wish they could forget was the final boss, a symbiote version of Doctor Octopus that became known as Monster-Ock. This terrifying abomination chased you through the final level of the game, creating nightmare fuel for gamers that stayed with them for years to come. Despite the sheer horror of this sequence, it's a delightfully thrilling scene that you just can't get enough of. Monster-Ock has some spine-chilling vocalizations that will scratch at your very soul, tormenting you as you race for the explosive conclusion. Like the greatest horror movies, the Monster-Ock battle is exhilarating in its ability to torture you, and yet make it fun all at the same time.
