The sheer magnitude of Santa’s powers are often underestimated, simply because he’s not an aggressive or combat-oriented powerhouse (unless cornered) but there’s a lot more than simple speed involved.

Either he’s drawing toys from a basically infinite supply in an alternate dimension, or he’s teleporting them from his workshop at the pole – there’s no way he’s carrying all that. He can walk through walls, penetrate any obstacle – probably demonstrating quantum-level control of matter and energy fields. He’s impervious to both heat and cold – demonstrated by comfort in chimneys and flying at 35,000+ feet in an open conveyance. Hell, if he’s not suspending time entirely, he might as well be.
But the biggest feat of all is a nigh-omnipotent surveillance and data retrieval system. He sees you when you’re sleeping. He knows when you’re awake. He knows if you’ve been bad or good.
Consider the implications of that. He’s monitoring and storing the level of consciousness of literally billions of children, processing all of it to give a positive or negative score on a scale of relative morality, and factoring all of *that* into a precise toy/coal delivery algorithm that happens instantly.

Santa Claus may not be a God. He may not be a Supreme Wizard. He may not be a Celestial-class being. It’s impossible to tell. But no matter how you slice it Santa is an immensely powerful being with a very specific set of abilities which have evolved over thousands of years to make him perfectly suited to a very specific annual function.
