Nicol Bolas maybe

still my all time favorite MTG dragon.

Niv Mizzet and Nicol Bolas?

Seconded!

Nicol Bolas was always my favourite.

How about this one?

Furnace Dragon!

Niv Mizzet!

Teeka's Dragon: http://www.wizards.com/global/image.....24_pic1_en.jpg

I have a lot of nostalgia for this one. Plus, artifact dragon so it's unusual there too. :)

Well, you can't possibly go wrong with Niz-Mizzet: http://31.media.tumblr.com/293bee98.....r1uo2_1280.jpg
But myself I have a soft spot for Drakewing Krasis: http://25.media.tumblr.com/f4002536.....r1uo1_1280.jpg

Might I recommend horde smelter dragon

Or flame blast dragon

I have always wanted Niv, Nicol Bolas, Treva, and Rorix.

Karrthus was already brainwashed by Nicol Bolas, so he'd probably make an easy target. :)

Malfegor also seems like a fun target, and he's a demon dragon:

And I'll toss in one more, Two-Headed Dragon for some nice double-hypnosis:

Treva

Nicol bolas all the way" http://static1.wikia.nocookie.net/_.....r_657x1022.jpg

Nicol Bolas and Niv Mizzet sounds like fun dragons to hypnotise.

Nicol Bolas and Niv Mizzet have good backstory. The other dragons don't have much depth to them

Thundermaw Hellkite

Could dragon, being an illusion creature, would be perfect, I thinks http://www.freewebs.com/goldenhorus.....14981Cloud.jpg
Also, moonveil dragon http://media.wizards.com/images/mag....._2560x1600.jpg

oy. So many dragons in MTG. So many good ones too!

Naturally, Niv-Mizzet and Nicol Bolas are two of the biggest and best.

But there are some other's that are nice. I have to admit, the newer dragon Drakewing Krasis is pretty cool too!

Intet is also really cool too.

Oros is always cool too!

Scion of the Ur-Dragon is also awesome-looking.

Otherwise, all the others mentioned so far are also great picks. You can't go wrong with them. :)

hah, guess I'm not bestial enough to give you interest as a subject for hypnotism :(

Numot, malfegor, helkite overlord or bladewing

Or Teneb or Vorosh

Nicol Bolas hypnotyzing Niv-Mizzet hell yes

Niv is the obvious one, but Crosis the Purger 's been around for a while and would be interesting given his power.

Niv Mizzit!

Although his existing art isn't the best, Karrthus is a beast at controlling other dragons!

If you're looking for a story, perhaps you could display how Chromium got to be so shiny and robotically obedient.

Can't forget one of the original greedy drakes, a nice powerful red that naturally just wants to die when he's without any treasure.

Smug grins of disenchanted contentness sometimes need fixing too. Probably would be good friends with old Ink-Eyes having a party with everyone's ancestors.

With suggesting the previous, might as well round out the PC cycle with the life-thirsty one that probably grows bigger and dumber with every tasty nibble.
http://magiccards.info/scans/en/cmd/235.jpg

Definitely looking forward to seeing the ones you've already chosen.

Could also look at Numot, the Devastator: http://fc04.deviantart.net/fs71/i/2.....ev-d3ieox7.jpg

-and- Darigaaz, the Ignitor: http://www.wizards.com/magic/images.....gniter_640.jpg

There's also the oft forgotten Dragon Mage: http://www.mtgedh.com/wp-content/up.....ragon-Mage.jpg

Skithiryx....that is all

Surprised none of the Kamigawa dragons have been mentioned.

Jugan, the Rising Star
http://www.wizards.com/magic/images.....r_1280x960.jpg

Keiga, the Tide Star
http://www.wizards.com/global/image.....23_pic1_en.jpg

Kokusho, the Evening Star
http://www.wizards.com/magic/images.....ening_Star.jpg

Ryusei, the Falling Star
http://i215.photobucket.com/albums/.....g-Star-Not.jpg

Yosei, the Morning Star
http://www.wizards.com/magic/images.....rning_Star.jpg

If I actually knew any of them, I'd add suggestions, but in the mean time I'll just watch curiously :)

Haha, mostly involves a planeswalking magician that entrances various powerful draconic entities. :D http://www.furaffinity.net/view/12366048/

...Least that's what the pictures are gonna involve. XD

Ahh, what else do you do with powerful draconic entities? :)

First kinky things! :D

...Then he usually has them around as pets. o: Nothing like seeing a highly intelligent beast/being acting like a delighted puppy. <:

Yes, I can see the attraction of that :)

As well as he can conjure them for battle once he's bound them to his will. :)

Next! A blueish wyvern .:D

Everyone needs a wyvern :)

Especially a hypnotized wyvern! :B Or a wyvern that used to be a person! <:
