what are the antonyms for exist generally?
lose, surrender.
is this a euphemism? nowadays, they are mostly synonyms; for instance, the treccani dictionary defines “adesso” as:”a more common and familiar synonym of ora, especially in northern italy.” evil doesn't really exist. it's a religious concept. 
 
the potential to do bad stuff though... that exists both within and outside. Sie is the standard formal form. In the past (lets say you read texts older than 50 years) Ihr was also used as formal form.


<http://wiktionary.de/> helps with your second question. Easiest way to look at them is to use the infinite (as mögen, haben, etc.). You can also search for inflections (as möchte, hast, etc.). This will lead you to the infinite page anyway. On the infinite page, theres this table and at the end of the table is a link that will show all inflections. You can call atty. No, there are quite a few by my count. I actually have a list I use to keep track of them all for various programming purposes on this site. Here's the list I have:


* Pichu (Spiky-eared form, HGSS-only)
* Unown
* Castform
* Burmy (but the Wormadam forms it evolves into *do* have different stats to each other)
* Cherrim
* Shellos/Gastrodon
* Arceus (each Plate technically gives it a different form)
* Basculin
* Deerling/Sawsbuck (seasonal forms)
* Keldeo
* Genesect (with Drives)
* Vivillon
* Flabebe/Floette/Florges (except for the unreleased Eternal Flower Floette which has higher stats)
* Furfrou (the various hairstyle "Trims")
* Meowstic (more of a gender difference than form, but they are technically different and have different learnsets)
* Xerneas (Neutral/Active Modes)
* Oricorio
* Alolan Rattata (but not Alolan Raticate)
* Alolan Vulpix (but not Alolan Ninetales)
* Alolan Geodude/Graveler/Golem
* Alolan Grimer/Muk
* Alolan Marowak


Also, the alternate Rotom forms have the same stats as each other, but different to the base form. a) van der waals (present, all molecule/atoms contain it)[readmore](b) dipole-dipole (present, c=o creates a partial charge on c and o)(c) hydrogen bonding (not present, h-bonds are only present in compounds with h attached on o, n or f)(d) ion-ion (not present, only appears on compound with full charges) here are a few that i usually recommend: 我會盡力若有誤請見諒
