Solgaleo

Solgaleo is an unenviable position. Not only is it forced to utilize the trash-heep of a moveset outlined above, it also had its Signature Move, Sunsteel Strike, given to Dusk Mane Necrozma exclusively. With this move, Solgaleo could be a strong Steel Type attacker, especially if it ever gets a Steel Type Fast Move. But, for now, Solgaleo is nothing more than material for the aforementioned Solgaleo fusion.

Best PvE Offensive Moveset

• Sadly, Zen Headbutt and Psychic Fangs makes up Solgaleo's only same-type moveset worth mentioning. To put how bad this is into context, Fire Spin and Flamethrower make up a pretty mediocre Fire Type moveset, and Solgaleo doesn't have STAB on them, yet they still out-perform its STAB set. Yeah.
• Iron Head is actually the optimal Charged Move, but it's a bit harder to pair with Zen Headbutt or Fire Spin.
• Solar Beam is okay.

Fire Spin is a rather average Fast Attack, but it has far superior energy gain and coverage compared to Zen Headbutt, sacrificing a very minimal raw damage loss.

Psychic Fangs defines Solgaleo - it is very spammable, and the constant Defense drops allows Solgaleo to rack up plenty of hard-to-mitigate damage. Iron Head is typically chosen as the second Charged Attack to more reliably damage Rhyperior and the Kyurem fusions, as well as being Solgaleo's second cheapest attack. Solar Beam can be used to surprise some Ground- and Water-type targets and is Solgaleo's only nuke option. Flamethrower is often redundant as Fire Spin combined with Psychic Fang's Defense drops offers enough Fire-type damage, but it does allow it to burn through other Steel-type Pokemon when Fire Spin's damage is not enough.
