Here it is folks, the final one! 52 weeks, and 52 new monsters for D&D. I'll try to get the .pdf compilation ready over my vacation (this coming week).
Anyway, for the end of the year, here's Father Time.

Father Times are grizzled old men with long flowing beards, typically wearing somber hooded robes and carrying a scythe.* They are only harmed by magical weapons and spells, and are immune to spells of 3rd level or less. In combat, they may attack with their scythe or may touch a target, causing either 10-40 years of aging (as a Ghost), or 10 years of reversed aging (as a potion of longevity). They may also use the following spells as a 15th level caster: Haste/Slow, Dispel Magic at will, Timestop 1/Turn, Disintegrate, Teleport 3/day. Any creature slain by aging cannot be raised by any means short of a Wish spell. Any creature slain by reverse aging transforms into a Baby New Year, a cherub-like sprite with 1HD but similar resistances and spell powers as a Father Time. If the Father Time is slain but the Babies New Year are not, on the next New Year's Day, one Baby transforms into a new Father Time.
*treat as a battle axe for systems that don't have it listed and use variable weapon damage, two handed, 1d8 damage
