No Lickers in RE7. Their presence in the RE3 remake is kind of a surprise, although maybe it shouldn't be: They appear only upon reaching a certain location from RE2, which makes sense. But the original RE3 didn't even do that much, instead introducing two different "new" enemy types that were just re-skins of Lickers without the tongue. So it's definitely an improvement.Introduced in Resident Evil 2, lickers have become one of the de facto enemies in the series, returning in Resident Evil 5, Resident Evil 7, the Resident Evil 2 remake in 2019, and the Resident Evil 3 remake in 2020.
You learn a lot about the rando you're playing RE5 with when you reach one of the two brief sections where you have to walk (not run) down a couple hallways and open a door as quietly as possible to sneak past an army of Lickers. It's the only part of the game where you're not rewarded for doing everything the biggest, loudest way possible, and without voice chat, it's often a big question mark whether your partner knows enough about the game or Lickers in general to pick up on the environmental clues and not to invite the hordes to come a-licking.
Shout-outs also to the green "Super Lickers" that only appear in a few rooms in the laboratory in the original RE2. It's "nice" to have such a nasty surprise that close to the end of the game.
