RP Pet battle teams

This has been something I been wanting to make a post for some time because I know some people on the RP realms like pet battles.

Topics are the following:
What pets do you use that fit into the RP of your class (example being Nexus Whelping, Lofty Tome, and Water Waveling for mages).

Sub types within the type itself, like Vampirc Batling, Scourged Whelping, and Giant Bone Spider all are undead but more than just undead, as the Batling is part bat, the Whelp being part dragon, and the Bone Spider being part spider.

Let's hear some teams you think you can fit into a RP's type.

Disclaimer: I do not RP. Just came up with the idea.
