The second ''Franchise/{{Castlevania}}'' game for GameBoy. You play as Christopher Belmont again, but this time, Dracula has kidnapped his son, [[strike: Soleil]] Soleiyu Belmont. Has smoother gameplay than [[VideoGame/CastlevaniaTheAdventure the first GB Castlevania]], and also (uniquely for the series) has a level select feature at the beginning, reminiscent of the ''VideoGame/MegaMan'' series (so the first four levels can be played in any order).

!! ''Belmont's Revenge'' provides examples of:
* AutoScrollingLevel: The bossfight against the Skeledragon. Because of Christopher's slow walking speed, [[ThatOneBoss this battle easily becomes a slugfest.]]
* BlackoutBasement: One level contains a scene in which the lights go out constantly. The quickest way to keep the lights on is to throw holy water on the ground.
** Or to not whip any candles in the room, keeping the room lit.
* {{Bowdlerise}}: The English version replaced the song names to generic BGM # names because of Nintendo of America's censorship against religion.
* BrainwashedAndCrazy: Soleiyu Belmont
* DifficultyByRegion: The Boomerang Cross is only in the Japanese version while the Axe is only in the American version. Which version is easier may therefore be a matter of opinion.
** Additionally, some of the items hidden in walls are different depending on the region.
* DualBoss: Plant Castle and Cloud Castle bosses.
* HailfirePeaks: A couple of the Castles mix and match level settings.
** Rock Castle mixes TempleOfDoom and UndergroundLevel.
** Crystal Castle is your run of the mill over water level with a crystal city.
** Plant Castle mixes JungleJapes and UndergroundLevel.
* EasyLevelsHardBosses: Unlike the predecessor, Bosses are typically harder than the levels themselves.
* KaizoTrap: In the Plant Castle, standing under the defeated bosses for too long results in the only obstacle in the game to OneHitKill you.
* ManOnFire: Flame Knights walk back and forth.
* MeaningfulName: Soleil is the French word for "sun." Becomes a clever MythologyGag when you remember the famous line from ''VideoGame/CastlevaniaIISimonsQuest'':'' "The morning sun has vanquished the horrible night." ''
* PuzzleBoss: Dracula is kinda this in this game; because all of his movements are predetermined, the battle will always play out the same, and the player only has to seek out the safe spots where he can't be hit by Dracula's SphereOfDestruction move.
* RevengeOfTheSequel
* ShedArmorGainSpeed: The Iron Doll boss does this when damaged enough.
* SpikeBallsOfDoom: In Cloud Castle, there are a couple Spike Ball traps that hurt Christopher.
* TemporaryPlatform: Some portions of the game have platforms that deteriorate for every moment Christopher stands on it. Take too long and it collapses.
