In the fifth game, there was still an alt-upgrade that they never implemented, even though they wanted to. And here, the sixth game added its own 3 tiers of creatures instead of 7. Ranks are great, of course, but I'm afraid this is already a relic of the past.
As for the fourth game, there is no correspondence, unfortunately, although something can be devised.

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
