I feel like I have too many Kumi, so I'm thinking I should change Marta Haakonsson's species. So before I do this A) Do you think it's necessary that sibling pets should be the same specie(Her brother is Xaen, and they're twins), B) Does undead specifically mean that a pet should be graveyard, and C) Of course, what Colour/Specie should she be?
There's personality info on her profile, but basically: She died in a car crash, she's from Sweden, she's an artist, and her favorite colour is blue.
A) I think that they should be similar in look or at least bear some semblance of being related, but no, they don't necessarily have to be the same species. c:
B) NO! Undead pets are ALWAYS GY. It's more fun to take a concept and apply it to a very different color. (undead angelic pet is interesting and unique than just another undead GY pet).
C) Well Keetos are always fun to use for anything undead because they're technically (I believe) reanimated dead things, hence the scars, sunken eyes, and strange aura. A Angel Keeto could work, but I don't know if that will appeal to you as Angelic is the most EXPENSIVE potion.

A Nightmare Darkonite or Malticorn might also work

Finally, Hydrus pets could make unique undead things.

I would say I'm the most fond of the idea of her being a Keeto. c:
I AM REPLYING TO THIS FIRSTLY BECAUSE YOUR HA IS JAMES SUNDERLAND. If I am wrong, shoot me. I swear it is. :D
I don't say that siblings have to be the same species. c: I say, go with whatever pet suits the personality more.
Some GY pets ARE awesome, but you don't need a GY pet to have have an undead/dead character. I agree with oddishness - it's far more interesting to have a completely unexpected colour, instead of mere Graveyard. /cuddles Tianna
As for what pets... hm. Some spectrum pets could work quite well, both ironically and for the 'artist' thing. Most with a nice overlay would work, actually. /failed advice there, sorry
A) No. Not in the slightest.
B) No. My Pet Gein is part Zombie ... so, he's somehow part undead (the reason why he doesn't age xD) ... and he's a Reborn pet. ^^;
C) What color/species?
I second that.
If they are twins yes they should be the same species
And graveyard is the best choice for an undead pet, but not necessary?

Wow, some good ideas here. I'm not that big on Malticorns (No offense, lovely pets, just not my thing), and I have another pet that I'll potion angelic. So I'm now split between several forms of the keeto(namely Spectrum and Nightmare, but several others too), the Nightmare and Spectrum Darkonites, and maybe some sort of Glade (I have some strange concept involving the plants being a reanimating force). Thanks for the ideas so far, and keep it up!
