- this would take place around s1-3 of friendship is magic
- Stardust can’t really actively use Hamon, Lucky tries to teach him but it doesn’t really work out. It’s just kinda powering him up until the end of the Dio fight, after which he starts to slowly learn a bit over time. he’s still not great at it though
- Dio has had much time to think/mind-train under the sea… however he was too weak to actually carry out any of the magic he thought about until 100 years later, where he broke free from the coffin and out of the ocean (no fishermen involved). He does his best to stay under the princesses’ radar this time until he’s sure he’s powerful enough to take the throne by force
- His grudge towards Starry’s bloodline becomes so intense that it manifests as a magical curse (think Starlight in that one episode but 100x stronger and reaches all the way across Equestria) Lucky and Stardust feel its effects, but it ends up hitting Holly the hardest, which starts them on their journey to find and kill Dio
- Dio learns of the centaurs abilities to absorb the magic of others, and spends his 4 years sucking not just blood but the very magical essence from his victims. this ends up making him about as powerful as an ACTUAL alicorn
- joestar blood => the bloodlines strong magical essence and their innate knack for hamon mastery, which is similar to celestias magic
- Emerald could’ve easily been turned into an “alicorn” vampony had he stayed on Dio’s side. just something to think about
