They are collectively called 'Daedra'.
A wide variety of creatures exist in the Oblivion universe. You have your basic animals; wolves, giant rats, bears, etc. An array of mythical creatures; Minotaurs, unicorn (yes ONE exists in the game), goblins, trolls, skeletons, ghosts, zombies, etc. Only one water animal exists in game. The Slaughter Fish ( elongated body, huge fangs, tries to eat you). With this you will also encounter many demonic beings in the plains of Oblivion themselves.
The daedric realm, Oblivion, is a different plane from the one in which the continent of Tamriel is situated. Creatures can travel to and from Oblivion through Oblivion gates, so presumably that's how daedra would travel to Elsweyr. (Note that this can not be done in any unmodded game).
you dont "get a dragon" in oblivion you fight some dragon looking creatures, you can capture a dragon soul, but you cant "get a dragon" sorry bud,
Im not quite sure what your asking, but the guardians of oblivion are the daedra, ( the guys who wield big weapons and run around wearing daedric armour) and most of the creatures in the oblivion gates ie: scamps, clanfear, daedroths, astronachs ect...
Oblivion took place in Cyrodiil. Skyrim takes place in Skyrim. Different countries, different people, different Daedras.
No because it cannot target the creature. Read the hexproof ability
You start talking to Ysabell instead of the battle master and do fights against creatures weekly for her. You can walk into the bloodworks at any time.
Pi is demonic
In Magic: The Gathering, planeswalkers are not considered creatures. They are a separate card type with unique abilities that represent powerful beings who can traverse different planes of existence.

Life was centered around religion in Stoker's day. Crosses were another way to show that Dracula and the Un-Dead were hellish creatures, unholy and demonic.
