Thanks for the compliment. This thing is much better fleshed out than older concept material I have, like "Pre-Tyrantrum Fossil dragon designed specifically to show how BST allotment is more important than BST" he was 495 BST with 85/180/35/20/35/140 spread
and some other junky things.
This one was also supposed to have a partner pseudo legend that was Ghost/Steel, more bulky, and would have a special variant of his ability it would have been a movie projector
What I came up for this one progression wise was: Punching bag inhabited by late fighter->Training dummy->Fully mobile thing like pictured>>18377004
Possibly. The main thing would be that it's ability would allow you to give it a good special pool and be able to dip into mixed without having to worry about ev/nature spreads. It's move type distribution would probably have to be partially limited, though, especially since it would have perfect coverage with Close Combat+Shadow Ball.
Of course I've also loved the concept of just having an ability called 'Spectral' as well, which gives the ghost immunities to a pokemon. Something like an Electric/Ice with that seems like it could be cool.
