I find the idea of someone weihte the Zombie Version of something very good
Lol! I support a zombie like monster 
(With flesh and stuff, not bones like skullrex :P)
Also if night and day is added into the game, I think it would be great if you can get a solar dragon in the day and a lunar dragon in the night. The dragons should be as rare as the other four dragons ie bluey and ashie etc and could even have a fusion to create an eclipse dragon!
I had thought just recently, have you done a turkey monster? It would be pretty cool as like a wild turkey or something like that, with a forestry kinda look, and it could be earth type. But I’m just saying it could be pretty cool if you did.
Yeah! Thanks for the drawings that is so cool! And maybe it could have 4 evolutions like the four elemental wyrms.
The dragons could be could lunawyrm and sol or solawyrm
Also season themed Arkadions would also be cool! Like a christmas reindeer, Easter bunny, thanksgiving turkey which can be released only during the time of season.
But they do not look like similar Arkadions with just a Christmas hat on. So they are different and unique Arkadions to motivate more people to play the game!
Also a black cat dressed up as a witch for Halloween!
Seeing as stego is bein nerfed, i still think charcalynx should be viable for pvp
Monster name: idk
Shadow type so it can be killed fairly easily
Moves:
Gentle touch- does about as much as a glazios rage claws (maybe a little less) but leaves one hp left, so if it attacks the monster with one hp after that, it does nothing.
Guardian
It should be fairly tanky, yet easily killed by holy monsters. This prevents permastun, but charca still has use. Hopefully not too op, changes might be in order.
A Chinese New Year ‘lion dancing’ lion thing for that event would be cool too!
What about a fusion with Dreadwolf and Tremorback. It could have Dreadwolfs head with a slightly longer neck with Tremorbacks shell for a body standing on two legs (which would be Soltusks hind legs) and its arms would be similar to Thunderbacks and would touch the ground so it would have an ape like posture (short legs long arms) with a shell body slightly longer neck and a maned wolf head. With a purple and green color scheme.
Another idea could be a hippocampus half fish and half horse, I think this would be great if it’s added to the game! I got this idea from the greek mythology, because since there is already a Cerberus I think this could be a great arkadion too!
A mechanical Crab that evolves in a lobster
A slug that evolves into a defense heavy snail
A jellyfish that evolves into a man-o-war
A golem
A ogre
A baboon
A pup that evolves into a Hyena
A couple more serpent based arks?
A work that evolves into a cocoon into a mantis
A centaur
A cockatrice
A lava kid that evolves into a golem
A few like element based monsters (carbon, hydrogen, oxygen, etc…) then you could make fusions for them like a hydrogen and oxygen could make some sort of water monster and elements that make things could make different monsters based of what they really make
A Foo Dog based ark
Comments in bold. ^^
The element idea is one I’m pretty proud of
haha and a foo dog is a Chinese based gaurdian dog it kinda looks like a lion but just cool 
I really like the idea of the foo dog, cause I think more mythical creatures would be great!
oh, that! I didn’t know they were called foo dogs. ^^;
I totally agree with Masterofgreen. I’m a big fan of mythical creatures and to see arks based on real life culture sounds very awesome!
Yeah mythical ones would be sweet
Griffins
Hell hounds
Sirens
Goblins
Titans
Nymphs
Demons
Hypogriffs
Chimeras
Etc.
There’s already a griffin, though i would love to see the rest. ^^
Duskroc, i believe, is also based on a mythological creature. So yay!
Cool I think nymphs, sirens, chimera and especially heaven hounds would be so cool! I think we a
Ready see too much he’ll hounds a heaven hound would give it an amazing twist! Also I think a hippocampus would be great, it’s a mythical creature that could look amazing as an ark, which to be honest we don’t really see and recognise enough.
Personally I think a white tiger and dark dragon yin yang thing would be cool as I miss fire tiger also maybe a metal detector shaped ark with a passive ability that increases the chances of finding a rare ark by like 5% or something? But don’t have the abilities stack in the case you have multiple
