Cheats. Love them, hate them, they are pretty much a staple of most WNs and LNs. But what is a cheat? Let's discuss! First off, in my humble opinion, the most important thing is that a cheat has to be outside of the setting's context. For example, Satou from Death March is incredibly OP because of his ridiculous level. However, that level itself is not a cheat, as it is something that is achievable for others (if near impossible). What is a cheat in his case is his ability to instantly learn skills and then level them out using skill points instead of practice like everyone else, something no one else in the setting has access to. Similarly, possessing an OP artifact or technique in a cultivation novel doesn't automatically make it a cheat, as those are still within the scope of the setting, but having a personal achievement store where the MC can purchase them with impunity is. So, let's do some categorizing (ps: I am not giving direct examples, but if you can guess which series I am referencing, you get 100 internet points :3): -Growth Cheats: These seem to be really common in both japanese and korean iseakais. The idea is that, due to some weird quirk (receiving multiple blessings from lazy goddesses, having a party member with a unique skill, powering up infinitely from doing pre-archery meditation, etc.) the main character is capable of powering up at a rate incomparable to the other inhabitants of the world. They may also have some other cheats on top of that (being able to switch around classes and skills, skill-stealing, etc), or it might just be that they overpower their opposition by out-leveling everyone so fast the bad guy's can't keep track and thus they are always under-estimated. Bonus points for being able to bestow the same leveling-speed to allies as well. -Future Knowledge: This can come in many forms, but mostly it's a staple of the second-chance reincarnation genre, though it is also common in the "transported into a fictional world as a character" genre as well. The idea is that the MC, one way or another, possesses knowledge of future events in the setting, allowing them to do things like snatch powerful artifacts ahead of time, thwart villainous plans, befriend and recruit future super-experts, or do all of the above while becoming kings or whatever. Alternatively, they might just try to avoid "death flags" and "bad ends". -Skill Acquisition: This seems to be most common in japanese isekai, and especially monster reincarnation Lit-RPGs (for obvious reasons). The most straightforward way is simply being able to pick up skills just by seeing them or trying them out once, without any of the necessary training. Then we have the more direct version, skill-stealing, where the MC usually consumes enemies, monster parts, or both in order to learn their skills. For added bonus, the MC usually has an automated ability that merges together low-level skills to form superior ones. -The System: This one seems to be very common in chinese isekai, where the MC is thrown into a (most likely cultivation-based) fantasy world, and they get an interface with a whole slew of options, such as quests, and achievement store, item-gacha, a minimap, and all sorts of other stuff. The goodies they can gain this way can range from techniques and artifacts already present in the world to the system being near-omnipotent and fixing everything for them, from their cultivation techniques to their love lives. -Out-of-context powers: Finally, this is the kind of cheat that may or may not be considered one depending on just how "out-of-context" it is, such as the MC suddenly being able to summon Magic the Gathering monsters and spells using cards inside an MMO-style litRPG, or the MC having the unique ability to power up items with +1 modifiers in cultivation world, or the MC not receiving a reincarnation cheat giving them so much mana it allows them to do way more impossible shit in their new setting than any cheat would. Whether or not these are cheats or "just" OP abilities usually depends on how far they are removed from the setting and whether or not they are considered rare but possible, unique but comparable to other abilities, or flat out impossible for anyone else by the rules of the setting. So, did I miss anything? If you think there are other kinds of cheats that slipped my mind, do mention them, along with which type of cheat you consider to be fun, tolerable, or a giant, pulsing zit on the face of literature.
