Crobat

#043 Crobat aka herobat
So here we get to what you think happens when we saw Mew transform Ash to save his love in pink skin by that he was too stoned to love anyone but does, so he became Lucario and we got to see a steel type pokémon with an anatomy, you know not like Magnemite robots, you think?

So Brock put a steel coating on Onyx and that's how the first Steelix we think showed up, and then in the war Ash evolved his Lucario transformation into Darknight, and since now their trainer can fly, all the golbats were like damnit, so they took metal into their builds and evolved to crobat!
