Here's a stab at Santa's powers. I'm sure others might have other thoughts.

1. Heightened Endurance B: +10
2. Heightened Charisma B: + 25
3. Body Power: Weight x 2 yet able to squeeze through the narrowest of chimneys. Defends as Stretching Powers, PR = 1 per use as a defense.
4. Cosmic Awareness: By asking yes/no questions with this power, Santa can discern if someone is sleeping (or awake) or bad (or good), etc.
5. Armor B: ADR = 50. As a built-in feature, Santa's suit defends as Adaptation against ice/cold attacks.
6. Vehicle: Reindeer-drawn sleigh capable of holding enough toys for children across the world and traveling at impossible speeds. (I don't see the reindeer as individual pets, but rather as an aspect of the sleigh.)

Body power: Excellent balance.  Santa never loses his balance, even on the most steeply sloped roof.
