Then I'll get onto your list, Sigma. Arceus is going to be a pain in the arse, between the "Each plate grants a different weakness, damage type for Judgement and immunity/resistance" and the "He pretty much created the Universe".

Psi Resistance: Poochyena automatically passes saving throws
against Psionics or Psychic effects. If an ability does not
allow a save and deals damage, it takes half damage. It also
gains a +4 bonus on saves against against Mind-Affecting spells.
Howl (Ex): If Poochyena fixes its gaze upon a target and howls
at them, as long as they can hear the noise they may be
frightened. This is a Standard action, and allows Poochyena to
make an Intimidate check (+10 without synergy) opposed by a
Will save. If they fail, which they probably will, the target
is Shaken for three rounds. If they fail by 5 or more, the
target panics for three rounds instead. No matter what the
result, any given target can only be affected once per day.

3d6 recoil.
