In Magic: The Gathering, Volrath has Greven.
- ... As Greven has his Vhati il-Dal.
- And Volrath himself was Dragon to Yawgmoth, until he was replaced by Crovax (and, later still, Tsabo Tavoc).
- Technically (at least according to the novels) Tsabo and Crovax were active at the same time, not to mention a Phyrexian-augmented Ertai, running about causing havoc. So it's more like a case of triple Dragons, no? Also, in that same block the 5 Dragons were awakened, each of whom had their own Golem Attendant, that could be considered their own Dragons.
- Ertai has more shades of Evil Genius; Yawgmoth would too, except that he's the Big Bad. The five dragons are more a case of Good Is Not Nice, though.
- In Kamigawa, Lady Masako the Humorless serves Emperor Konda as administrator, and she's a rather harsh mistress. Oh, and despite the trappings, she's not Konda's wife.
Konda's servants dared not neglect their duties for a moment under Masako's icy gaze, knowing that what she saw, Lord Konda would hear.
- In Conflux, Nicol Bolas (the Big Bad despite being a literal dragon) has Gwafa Hazid, Malfegor, and Rakka Mar as minions, but had to go for something extra special to lead them - Sarkhan Vol, a psychopathic, dragon-worshipping (and perhaps Brainwashed and Crazy) planeswalker. He also has Tezzeret, a planeswalker he has rebuilt after said planeswalker was Mind Raped and left for dead by Jace Beleren. Bolas has saved Tezzeret from death twice, so the latter owes the former a significant debt, albeit grudgingly.
