Essence of theGeneric Isekai Protag

This pastel-colored Essence seems to be very familiar, as if you've seen it somewhere before. Also, for some reason it smells faintly like truck exhaust.

• Upon drinking this Essence a friendly neighborhood ROB will immediately isekai you to another world. This will usually be a generic JRPG style fantasy world, but more rarely could potentially be any fictional setting you are familiar with. Wherever it is, there will be something going on that needs a protagonist to help solve it. Three guesses who that's going to be.

• Whether you dropped in, reincarnated into a "local", were summoned, or whatever else, you will still have a young, healthy, and athletic body that is highly resistant to common diseases with an appearance that is somehow just how you've always wanted to look, within the genetic limitations of your race. You may be any common race, not just human.

• You will be able to maintain your mental focus and think clearly even despite potential stressors such as being stranded in an entirely new world, being forever separated from all your friends and loved ones, forced to fight for your life, or being responsible for saving the world. This will also help you quickly learn and adapt to your new life, allowing you to master new skills, abilities, customs, etc., as easily as a very young child would pick up language skills.

• Regardless of your appearance, you will possess a blandly inoffensive charm and generic appeal that's so broad that it seems like people just can't help but like you. Unless they are explicitly your enemy, bear a significant grudge against your race/faction/etc., or are just the type to hate everybody, anyone you meet will have an initial favorable disposition to you and will likely be open to a lasting friendship if you put in the effort. Even some of the latter types might be brought over to liking you depending on time and circumstances.

• Even without your putting any effort into it you are still prime waifu bait. If you wish you can easily attract one or multiple romantic partners that you find attractive and be able to keep them all satisfied and at least tolerant of each other with relative ease. You will also have perfect fertility control and other minor, related buffs.

• As an outsider, things that everybody else has been overlooking all along just seem that obvious to you. You can think outside the box, you can readily spot flaws or oversights in local cultures, strategies, tactics, etc., and you can point these flaws out to other people and unless they were already set against you they'll probably listen.

• You will, of course, be granted the plot armor that is due you as the protagonist. Things will generally go your way and opportunities tend to fall into your lap as you need them. Unless you deliberately seek them out, your life will follow a progressive escalation structure where you will not encounter challenges or foes until you have 'levelled up' enough that you have a feasible chance to win against them. And even if you are defeated then nothing short of deliberate self-sacrifice or suicidal idiocy will actually get you killed as opposed to just beaten.

• Finally, you will get a singular cheat ability of your choice as an apology gift for your sudden case of isekai. Whether that be some type of Dark Wolf Shiro-worthy Gamer system, instinctive mastery of magic plus unlimited mana, half the stats of the most powerful creature in the world, being a super powerful race such as Kryptonian, Primarch, etc., Spiral power, or whatever else, you will receive a thematic power (or narrow powerset) that makes you the most important person in the story. You may not take anything that would start you as a peer of the ROB who sent you here.

• I tried to make this as generic a set of isekai tropes as I could while still geting it all to fit on a single page of a Word document. Hence you getting the blandly inoffensive appeal, the harem (with an opt-out for people who really don't want one, because I am not writing a curse here), the bit where the locals just seem to find all your uplift nonsense from another world that impressive, etc, etc.

• As for adjudicating cheat abilities - no, I won't. Please don't ask me. The general rule of thumb is, if you have to ask if it's too OP then it probably is. Given that I've already said that things like Primarch SIs and the canon "Didn't I Say To Make My Abilities Average?" are allowed cheats then there's still more than enough range for you to be powerful and have fun. And look, if you actually want omnipotence then go drink one of the many Essences that offers it, this is intended to be an actual theme package.

• That having been said, it's still generous enough to encompass shit like Shiro's Guild of Gamers, the aforementioned Primarch SI fics, suddenly being a Kryptonian in Worm, or any of the other actual isekai/SI fics we've all seen around, so I'm not saying you have to stay down in the mud killing 200 slimes a day, I'm just saying, don't be crude about it.

• PS: The threshold of 'suicidal idiocy' is basically 'if the protagonist was so fucking stupid that even Aqua would think this guy was a moron'. It's intended solely as a request to not abuse the plot armor so hard that the audience is praying for the idiot to die, but he just refuses to.
