Your screenshots are rather big in screen size. Next time, when you want to post images, put them in a spoiler.
Also, if you have any other question, and no one has replied you yet, simply edit the new question into your latest unanswered post. (basically, don't multipost )
I can't read Spanish, nor do I know the Spanish translation of various country names. Well, if those 3 boxes there are the same as your regular Pokémon, then it's correct.
This is probably something you should know best, and I won't be much help in that regard.
Before I go about answering your question, I need to clarify this point: the only events for Virtual Console Generations 1 & 2 that were released, is Mew.
(what I mean by Classic and Virtual Console)
Do not use any Classic events from Gen 1 & 2, such as PCNY, if you intend to have them in SM/USUM.
I'm bringing this up, because your intention is likely to have the mon in USUM, and I need you remind you that Gen 1& 2 cart cannot transfer up to Gen 3 and onwards.
The Classic events were only for cartridge versions of Gen 1 & 2, and those Pokémon cannot be transferred to Virtual Console Gen 1 & 2, nor can they be transferred to Gen 3 and onwards.
Agility Voltorb is a Classic event, so even if we uploaded it, you shouldn't use it for the reason stated above.
Going back to whats missing: I'll say beyond missing entries between Gen 1 to 3, we should have every other event.
