"[PSA] Ditto Mechanics"

#PokemonGO: I'll update this as I know more or you guys comment to make it a useful post but here are my observations so far (as well as info you've all dropped in the comments):Ditto spawns are indistinguishable from the Pokémon they're hidden as and even PoGo+ will treat it as the Pokémon it's hiding as so the reveal is only after it is caughtAnecdotally, Ditto spawns are harder to catch than their target TransformationsYou can catch more than one Ditto (as of now I have three)A hidden Ditto will appear the same to all players but will turn into a Ditto upon catching and can be caught with PoGo+If a hidden Ditto runs, your journal only says that the disguised Pokémon ran and your Ditto entry in the Pokédex is unchangedThe hidden Pokémon's badges are shown rather than Ditto's Normal Type oneDitto buddies have 3km distanceDitto automatically uses Transform if the first Pokémon is not DittoDitto will only use Transform once and will stay the Pokémon it transformed into even when swapped out, the source Pokémon is defeated, and swapped in to fight a new Defender.Ditto will Transform into the first non-Ditto Pokémon it sees as Defender or Attacker (two Dittos just chip each other)When Ditto Transforms, it seems to take the stats and moves of its target but keeps level (and presumably IVs) so the CP will be differentDitto does not copy a target's health so it is a glass cannonDitto's Prestige is based on the Transformed CP (so a high level Ditto is quite good to train against due to low HP and high CP)A Ditto's CP can exceed that of its targetDitto can not use Transform on a Transformed DittoDitto can, in fact, use Transform on Porygon even though it's copy-protectedBugs:My Ditto came back from the gym fainted but came back from a battle it lost at low HP but came fainted the second time around so there's a bug hereYou can not swap back to Ditto once it has been Attacking at least once unless it has faced a non-Ditto Pokémon (this may be a bug) I just tried again and it allowed it so it's an intermittent bugQuestions:Any Confirmation on Eggs?Any Observed Level requirement?Let me know if there's anything to add or questions answered. Thanks! I'll update it as often as I can but it's getting late where I live so I might just update it in the morning since edits from my phone are gonna be annoying.Edit: Well, updated the list a bit this morning. Sorry if I didn't replay to your comment directly.
