I'm asking this because in an Online Battle, It somehow dealt supereffective dmg to a Hisuian Samurott and still damaged Spiritomb even though it was a Ghost type. Is it something special with it's Terastal, or something else?
When Terapagos isn't in its Stellar Form, Tera Starstorm is a Normal type more with 100% accuracy and 5 PP that deals 120 damage. When Terapagos is in its Stellar Form, Tera Starstorm changes to a Stellar type move, at which point it damages all targets and hits Terastallized targets for super effective damage.
