I was just posting a comment about the move Steel Beam when I wondered: If you had a Zacian or Zamazenta in their Crowned forms outside of battle, could it learn Steel Beam?
First, I want to talk about Zacian and Zamazenta's Crowned forms. These forms are only used in battle and add the Steel Type to the legendary dogs, sort of like Groudon and Kyogre's Primal forms (but without that long opening animation that plays the first time they are sent into battle).
This is why I wondered: Because Zacian and Zamazenta gain the Steel Type when they are in their Crowned forms, what if they could be in these forms outside of battle? And if they can, could they learn Steel Beam like any other Steel type?
