>>29815263Type: null was a failed experiment yes, but silvally is something that exists solely by its bond with gladion, as it evolves by friendship (and key word evolves, doesn't just change forms, which would be the logical thing as the only change is the helmet being removed).
It was a great opportunity to make sylvally reach 600 BST and turn into the real UB killer aether tried to create, ironically because gladion gave it what aether never did: friendship, love, etc.
Instead they just boosted its speed. Don't get me wrong I still think its stats are very good specially with RKS system, but I see a bit of wasted potential story and lore wise.
