Sure, sure. Go for it.
So to those who try to pay attention to every news of Pokemon that GameFreak offers, who remembers Necrozma BEFORE the USUM games were announced? I recall the Pokemon fandom going nuts on the mystery behind Necrozma's role, purpose or what it even is with a lot of people curious of it's odd looking body, the fact that it's pitch-black and releases beams of light chaotically, shows that it has headaches in it's battle animation, is referred to as an Ultra Beast by Looker but Beast Balls aren't effective on it and that the Pokedex says this was a Pokemon that traveled from another world in ancient times. This was pretty much it. There was no relation to Lunala & Solgaleo, the fan term Light Trio never existed back than and Lunala & Solgaleo were just called the Cosmog Duo. Boy were a lot of theories shattered by the USUM game announcements and later the release. Although I do recall one reddit user who had this honestly almost insane theory at the time that Lunala and Solgaleo's body parts put together resemble not only Necrozma's bodyparts but also a dragon and the insane part is how spot-on he was when Ultra Necrozma was revealed. What are the chances of someone getting that right lol? Man, a lot of nostalgic memories of the Pokemon fandom around this Pokemon.
On a different note, who remembers the USUM games marketing heavily on the story this time? The big mystery of what and who Necrozma is and his relation to Alola? I remember the first announcement trailer garnered some negative reception but over time, the marketing started focusing on the story and the reception turned more and more positive. Honestly the Necrozma mystery was alright, could've had better build-up but man, in Pokemon Adventures SMUSUM, the mystery of Necrozma is just handled so well, so freaking well! The foreshadowing is spooky as hell, the build-up is suspenseful and the many people & organizations already involved in the mystery of Necrozma long before our protagonists, Sun & Moon find what's up about Necrozma is just so awesome! I especially freaking absolutely love what happened in the most recent chapter. In the anime's depiction of Necrozma, it feels like fanservice to Pokemon fans, that the Pokemon Company just added Necrozma in because they felt he needed to be there but they couldn't find a reason why he needed to be there and it's disappointing how they tossed out this one very integral "human" aspect of Necrozma's background but here the manga just freaking embraces it and he really feels more than just fanservice to the Pokemon fans but like a legitimate character without a voice that's read from two different viewpoints of the characters around him. I really, really, REALLY want to spoil how Necrozma is done but I won't. I will not but I really want to just spoil the mystery of Necrozma in the manga because Necrozma is just so interesting in Pokemon Adventures. Especially what happened in the recent chapter! Maybe, maybe I'll give one vague little spoiler but there is this really, really intense stare-down between Necrozma and another character and it's just so amazing and that's just the freaking build-up, I can't wait to see what happens in the next chapter and how it all ends. Honestly I felt like the games could've handled Necrozma better but the Adventures depiction might just be my favorite storyline revolving around a mystery of a legendary Pokemon.
