What would you think if it was Pikachu on them stone tablets

What if Arcanine seen on the ancient tablet was actually a particular powerful individual

Just like Pikachu but ancient and maybe reincarnated?

I was looking for support in this but it’s not much and idk if this universe supports it.

1. The color hinting at the next type yellow
2. Arcanine & Pikachu have evolved forms
3. Pikachu opposes the evolve (because Arcanine failed?)
4. There’s a ghost type of Arcanine later on
