Well, I'm a bit late to the party, so will have little influence on the results, (not that I ever do anyway), which might be for the best. Nevertheless, Imma post my very favorites first, then vote for some that actually have a chance.
As the plant advocate in this quest, first I vote for my favorite plant (in real life, not just here lol):
[X]
Rose
And then for some things every quest, and esp. this one, needs:
[X]
Cheshire Cat
because what this quest definitely needs is more eldritch cats. Since we don't utilize the ones we have nearly often enough, if we have a Companion one it's bound to appear in the story more.
[X]
Clifford the Big Red Dog
because what everyone, not just this quest, needs is more big friendly dogs. It's hard to get bigger or friendlier than Clifford.
[X]
Faerie Dragon
In every situation that it is possible, obviously you need more dragons. And who wouldn't want more Fey? This one is a twofer. How this isn't running away with the vote I'll never know. Think of the humor potential alone!
[X]
Asperii
We've made a nice start to our magical horse collection, but again, we obviously need more.
[X]
Turtwig
When lobbying for the Greater Companion, some one mentioned Pokemon, and indeed one is in the top voting. I, however, am voting for the
very best starter Pokemon. Come at me bro.
Now, for the ones that are already with several votes.
[X]
Ra-Seru (Legend of Legaia)
I know nothing of these creatures or their setting, but just from their reference page and what people have said, they tick several of my favorable boxes--eager to help humanity as a whole, dedicated and intelligent, benevolent, and appear to be a bit OP for their cost.
And finally, an old friend of mine--(I've been assured that even though he looks and sometimes even acts like it, the talking skull is really, really not an undead of any kind. I despise undead.)
[X]
Bob (Various: Dresden Files)
If anyone can help Alex give better magic lessons, it's this guy. Not to mention helping Alex himself with current and future magical abilities. [Edit insert: I just thought of this, since the world of Dresden Files holds Telepathy and esp. the kind that willbends, i.e. takes control of or influences thoughts, to be quite repugnant, Bob is likely to be quite repulsed by poor Starro.)
One thing I haven't considered is if any of these stand a chance to advance by going thru our dungeon, since that would be a big plus for a permanent Companion. But I'm sure either Rose or the Cheshire Cat could, so maybe they'll catch on in the late voting? Oh well....
