Ju Ju Zombie and upgrades

[Thane36425]

Can the upgrades like plague zombie be added to the Ju Ju Zombie?

Is there such a thing as a zombie champion like the skeletal champion? And if so, can it also take the improvements?

Zombie Lord is the zombie equivalent of skeletal champion.

One creature cannot be both a juju zombie and zombie lord at the same time, sadly. “Juju zombie” is an acquired template that can be added to any living corporeal creature. "Zombie lord" is an acquired template that can be added to any corporeal creature (other than undead) that has a minimum Intelligence of 3.
