To answer that question, I have to take you back to 2010, to the HeartGold version where I began egg breeding for a shiny. This Aron was probably the first I ever tried to gain a shiny for with the well known 'Matsuda Method.' We all know it came from the Safari Zone in that game and I really liked the look of it despite passing by the third generation when it was introduced. I grew very fond of it as I waited for that moment to come into the following year before giving up entirely. In the end, I had no shiny Aron but plenty of regular ones to trade away to the GTS, growing my collection as I had found my mark. That didn't matter - it won me over in a matter of days.
Also, it has the evolution stage that's reserved to many of the starter types; from simple cuteness to full-grown buttkickery. I love it so much so that I started a physical collection of any featured merch from the mid/late 2010s to this day. That's a level of dedication I'd wish for anyone to try, no matter how obscure their interests lay. I hope to share that collection with all of you someday. 🤍
