We saw that he can "link" himself up with Lucy even after appearing under his own power in the Tenrou arc, so we can't say for sure that he fought the Garou Knights and Royal Army under his power or with Lucy's. Also both the Garou and Army are nowhere near the level of the Demon Gates, so even if he took care of the fodder with his own power, it would still hold very little impact on the current fight.

And while I don't have all the details in my head right now, wasn't it only Pisces and Aquaruis that defeated that Garou Knight? If so, all Loke did in the entire arc was delivering the keys and fighting fodder.
