10. The Giant Snake/Alligator/Spider/Plant
The giant snake in the original RE was a major block to me playing the game. I got killed so often by the freaking thing, I couldn't bear to play. The snake doesn't just wound you, it poisons you and tosses you around like a rag doll. And then one day I beat it. I was so proud, I treated myself to a wee Guinness and a lie down. The alligator first worries Ada in RE2 and it is up to Leon to bail her out (again - he just took a bullet for her). Trying to shoot at this behemoth croc does not yield any good whatsoever, he comes slowly and relentlessly. I was gobbled up several times by the greedy brute until I copped on to the switch that releases a canister. Let the alligator get that in his gob and then shoot. This results in an impressive amount of crocodile brains being splattered everywhere. Giant spiders are scary to those of us with arachnophobia. Thankfully they are easy to kill but sometimes they have babies. In the sewers in RE2, there is a congregation of giant spiders trying to poison you. These are easily dodged, but it is funny to get them to poison Ada/Sherry. Actually it isn't with Sherry, if you run too fast, she sits down. Repeatedly and annoyingly. Evil plants that spit acid are par for the course in RE. But they are confined to RE1 & 2. There is a huge plant in the first Resident Evil game that makes a big display of trying to kill you. Then there are the Day of the Triffid like plants in RE2 which spit their acid pretty damn accurately. I once died by death from acid spit. Three of the buggers cornered me and let rip. So as you can see, giant anything is game for scariness in Resident Evil. Oh I forgor about the giant moth in RE2, but that was a bit of a rubbish monster.
