History VideoGame / GachaWorld

** Undy causes a [[WaterIsBlue blue colored water bubble]] to encase the enemy and burst to deal damage when summoned.

* UsefulNotes/BlueScreenOfDeath: Parodied in the game over screen from the [[BulletHell bullet hell]] minigame. The background is still blue despite being much more saturated (it's close to #00f) than the real thing and also the text is still white but it instead tells you to quit or retry instead of restarting your device.

* TrueFinalBoss: [[spoiler:Ellie gets taken over by corruption and snatches your weapon to use against you after [[EveryoneCallsHimBarkeep Final Boss]] gets defeated in the story.]]

* BizarroElements:
** Candy Tanuki summons candy rain from the sky all over her enemies.
** Chocolate Clover summons three gigantic chocolate clovers that are irresistably tasty and kills her enemies by them overeating her chocolate summons.
** Dice literally throws a massive dice that [[ShoutOut explodes and deals damage on a six and deals zero damage on a one]][[note]]For those that don't know, exploding dice is a system where if a CriticalHit is rolled, that dice gets rolled again until it is no longer a CriticalHit and all the previous [[CriticalHit critical hits]] are added up to the grand total.[[/note]] when summoned. There's 50% chance to [[CriticalHit roll a six]] and be over with it or failing that roll, a separate 50/50 roll of either a [[CriticalHit six]] or a [[CriticalFailure one]].

* DefeatMeansFriendship: Upon beating every boss inside story mode and challenge mode, they each return to normal and continue their daily lives after returning the favor usually by befriending you through recognizing your efforts to bring them back or in one case, gives you a free means of ocean travel.
** Subverted by the [[EveryoneCallsHimBarkeep Final Boss]] as the FinalBoss is never friendly to begin with and never befriends you afterwards either.
*** Double subverted because the stage number that you fight FinalBoss on is not the end of Act X therefore is not the true world 10 boss.

* ElementalPowers: For a game that is based on ElementalRockPaperScissors, there is as expected, many elemental powers showcased in the units' summon animations. Technically TheProtagonist, being a gacha summoner while wielding the gacha sword, can make use of all elements (that exists within the game) via both summoning their respective wielders and also the ability to gacha summon is an applied example of [[TimeMaster time]] and [[SpaceMaster space]] powers as it is shown to summon beings from different worlds and timelines. The elements in question are water, fire, wind, light and dark.

* BioManipulation: Pretty much every healer unit in Gacha World is supposed to do this to varying degrees of ([[ScrappyMechanic in]])effectiveness but some deserve special mention.

* ElementalPowers: For a game that is based on ElementalRockPaperScissors, there is as expected, many elemental powers showcased in the units' summon animations. Technically TheProtagonist, being a gacha summoner while wielding the gacha sword, can make use of all elements (that exists within the game) via both summoning their respective wielders and also the ability to gacha summon is an applied example of [[TimeMaster time]] and [[SpaceMaster space]] powers as it is shown to summon beings from different worlds and timelines.
* ElementalRockPaperScissors: A very basic example where elemental bonuses deal 1.5x damage and elemental weakness deals 0.5x damage. Water is strong against fire but weak against wind, fire is strong against wind but weak against water, and wind is strong against water but weak against fire. Light is strong against dark and dark is strong against light. Everything else deals regular damage.

* DarkerAndEdgier:
** Characters corrupted by the FinalBoss all act darker and have edgier speech than they normally do. [[DefeatMeansFriendship They return back to normal when cured by being defeated.]]
** A specific example is Yume, a light unit, who becomes a dark type when corrupted into Nightmare Yume which is her boss form in Act VI.

* DarkerAndEdgier: Characters corrupted by the FinalBoss all act darker and have edgier speech than they normally do. [[DefeatMeansFriendship Returns back to normal when cured by being defeated.]]
** Yume, a light unit, becomes a dark type when corrupted into Nightmare Yume which is her boss form in Act VI.

** Undyne causes a [[WaterIsBlue blue colored water bubble]] to encase the enemy and burst to deal damage when summoned.

** [[UpToEleven Yume, a light unit, becomes a dark type when corrupted into Nightmare Yume which is her boss form in Act VI.]]

** The game has many units that prioritize ATK over HP, but some are very blatantly more so than others. Take for example, Senpai Slayer Kuku which has roughly 100x more ATK than HP at max level (level 300) and exaggerates this even further with [[UpToEleven a leader skill that multiplies team ATK by 2x while dividing team HP by 10x]]. Scythe Ripper's leader skill comes in second where it multiplies team ATK by 1.9x and then divides team HP by 5x.

* StarPower: Starlight Ellie drops numerous five-star gacha stars onto all enemies when summoned.

** With a gesture, Inferno launches a wall of fire to his enemies when summoned.

* BossBonanza: In story mode, every world has five NPCs where the last one of the five is the boss enemy of that world ... or so you thought. When you finally defeat the last NPC of world 8, which is a boss enemy, you reach world 9. And in world 9, every single NPC is a boss enemy. Then after defeating all five of those NPCs, you reach world 10. And lastly, the first NPC you encounter in world 10, being the only NPC there, is the FinalBoss.

** Kilios is a [[Pun speedrunner]] inside Xkour and outside of the game, Kilios is a speedrunner in real life.
