We know it's hard to design new dragons, that's why every now and then we find some dragons that look pretty much the same. This includes dragons that have the same body shape or share parts, usually differing only by color and small detains like horn shape or hair.
Post some suggestions for dragons with similar looks and I'll look for their pictures and add them to the list.

Arena dragons
Most arena dragons are an armored version of an already-existing dragon.

• Terra : Terra and Bjorn (by @AugustRyutsuki)
  

• Flame: Flame Dragon, Katsumoto and Wax Dragon (by @AugustRyutsuki)
  
  Where did Katsumoto's horns end up at?

• Sea: Frozen Wind Dragon and Lancelot (by @AugustRyutsuki)
  
  Same problem here: how can that helmet hide the big fin on top of Frozen Wind's head and its ears?

• Nature: Orc Dragon and Fury (by @AugustRyutsuki)
  

• Electric: Mantis Dragon and Mighty Mantis
  

• Ice: Alien Pet Dragon and Frostling
  

• Metal: Phantom, Usurper, Warlock, Wolfish, and Ironscales
  
  Phantom's pelvic bone looks like Usurper's trunks.

• Dark: Cowardly Dragon and King Ragnar (suggested by @AugustRyutsuki)
  

• Light: Martian Dragon and Emperor
  

• Pure: Werewolf and Wailing dragons
  
  Maybe Lancelot decided to lend his medieval armor to the werewolf? Also, I chose to depict the youth stage because wailing loses the rock and the chains upon becoming an adult.

• Legend: Warfare and Shredder dragons
  

• Master: Kitsune, Norse and Samurai dragons
  
  All of them don a weapon and a shield. Kitsune has hair while norse doesn't, so that's the reason for his fox-related name.

Traditional dragons

• Amber and Dark Angel dragons, specially in their youth stage:
  

• Archaic, Bubblegum and Online dragons
  

• Arctic, Drace and Freedom dragons
  

• Augmented, Cake and Wilderbeast Dragon
  

• Beach and Dorothy dragons
  
  They have the same eyes and head shape. Beach also has the same broken tail as High Resolution.

• Belieber, Matroix and Tuber dragons (by @AugustRyutsuki)
  
  

• Betrayer and Crystal Carrier dragons
  

• Black Magic, Merchant, Protector, Root and Valiant dragons
  
  All of them hold a weapon. Their animation consists of throwing the weapon up in the air, which will spin and land back into their hand.

• Blade, Catacombs and Iced Sea dragons
  
  Did you notice the chipped claws?

• Blue Alien Dragon and Mystic Tribe Dragon
  

• Blue Fire Dragon and Double Flame Dragon
  

• Boulder and Football dragons
  

• Brave and Stinger dragons
  

• Breaker and Hard-headed dragons
  
  Both are primals, but breaker is breadable while hard-headed is not.

• Brontosaurus Dragon and The Good Dragon
  

• Bull Dragon and Gladiator Dragon
  

• Bunny Thrower, High Portal and Knife dragons
  

• Butterfly Dragon and Summerfly Dragon
  

• Bushido and Cereal Killer dragons (by @AugustRyutsuki)
  

• Callux Dragon and Ranoldo Dragon (by @AugustRyutsuki )
  

• City Shark Dragon and Ratabite
  

• Cloudberry and Notus
  

• Coyote and Winter Comet dragons
  

• Dandy, Striking and Swamp dragons
  

• Dangerosaur and Vulcan dragons, except for their adult stages
  

• Dark Ash and Zephyrus dragons

• H2O Delirious Dragon and Jason Dragon
  

• Headstrong Dragon and Neumon Dragon
  

• Health Potion, Liquid and Mana Potion dragons
  

• Hercules , Skull and Trihorn dragons
  

• High Realm Dragon and Kong Dragon (by @AugustRyutsuki)
  
  Kong's wings also show up on the High Tension Dragon.

• High Snow and Shielded dragons
  
  Their giant feet gave it away. I also see slight similarities with Gear, High Star and Trickster Fae dragons.

• High Supremacy and Vulcan dragons
  
  They are both designed after a t-rex with small arms and fleshy thighs.

• Hoodini and Vanoss dragons (by @AugustRyutsuki)
  

• Horai and Slugabed dragons
  

• Huntress and Whimsical dragons
  

• Hyperion and Tamtam dragons
  

• Ice King and Topaz dragons
  

• Iceberg Dragon and Symbiotic Dragon
  

• Iceling and Mindrake
  
  Maybe mindrake is just how iceling dresses when he goes out partying with his friend, the disco ninja?

• Intraterrestrial Dragon and Spiderknight Dragon
  

• Ivory Dragon and Red Asian Dragon (by @AugustRyutsuki)
  

• Landslide and Sola-powered dragons

• Padron Dragon and Spicy Dragon
  

• Peculiar Dragon and Sackman Dragon
  

Praetorian and Voltaix dragons

Surprise! Everyone thought Praeterian would be the reward for reaching the war arena, but he was relocated to the warrior's chest. Also, helmetception: Praetorian apparently wears a space helmet under the gladiator helmet.

• Pure Gold and Unbreakable dragons
  

• Recycling and Sustainable dragons
  

• Reddishi Dragon and Wingspan Dragon
  

• Super Bowl and Touchdown dragons
  

• Yang Dragon and Yin Dragon (bu @AugustRyutsuki)
  
  The twins.

Breedable dragons
These dragons are supposed to have similar looks as they are related to the same elementary dragon.

• Electric family: Electric, Fluorescent, Laser and Neon
  

• Flame family: cool fire, flame (old model) and medieval
  
  The design of the flame dragon is the most traditional. We could also include mercury, soccer and zombie in this category.

• Ice family: Alpine and Volcano
  

• Metal family: Gold, Metal and Platinum (by @AugustRyutsuki)
  

• Sea family: Cloud and Storm
  

• Terra family: Flaming Rock, Hedgehog and Terra (old model)
  

The new heroic high portal and high realm dragon.

Also blizzking dragon and iceking dragon. They even have the same description. Well almost anyway. Go check them out.

I am not seeing it with either pair, yes Realm and Portal have similar feet but that is it. And with Sky king and Blizzking they have totally different body builds, so no I am not seeing those two as twins or even siblings.

There are a few pairs though I am drawing a blank at the moment... I believe a few were mentioned in the New Dragons thread.

@Nynaevelan ice king and blizzking. No Sky king.

@Nynaevelan ice king and blizzking. No Sky king.

Sorry, my fault.

Comparing both, they have different feet, wings, tails and faces. They don't look alike after all.

Design wise maybe. See description.

Here I Think same animation
Pursuer Dragon seems like Red Witch Dragon

I can only edit the main post once per hour before it gets marked as spam. I don't know why that happens.

@Bruno-Pedron It sometime come new dragon that same design as the older one..
Check my comment again

Pretty sure Ozone and Drace, especially the babies, have copy/paste heads and identical animation.

@BathtubDoritos They look very similar because they are both birds. Asides from the head, their body structures are different, as one has six limbs and the other has 4. Nevertheless, I have added their child stages to the list.

there is this particular dragon that looks like Pluto god dragon but I can not remember the name

@samioes-free234 said in Dragons that look alike:

Maybe Glutty?

@arranos no another one

and also Dumbpling, Nobunaga and Conqueror dragon

High star and Wishing star dragon

Past and Future Dragon

Praetorian, Gauntlet and Voltaix Dragon

Eggster and Red Egg dragon

Prosperous rat appears to be a reskin of tailwind, and crystal carrier looks to be copying betrayer, too. Exotic and world wonder are clones of terra as well.
Edit: the monarch dragon looks familiar, but I can’t quite remember what it’s a reskin of. Could somebody tell me if they figure it out?

Sea Virago and Dancing dragon

Vibrant, Mindrake and Iceling Dragon

Ice King Dragon and Topaz Dragon

Slugabed and Horai Dragon

Katsumoto Dragon and Flame Dragon

Hey does anyone else think the summer fly dragon is sorta a waste? It could be remade into a Skin for the butterfly dragon and be free for players who had summer fly dragon before it was replaced by a new one (because if this happens you can’t have an empty dragon space in the book.)

No it isn't for those that have been around since the first couple of years they know that Summerfly used to be the special butterfly dragon that looked EXACTLY like the Butterfly, they reskinned it to be the Summerfly. So no us vets do not think it is a waste and we aka I would like it to stay around for nostalgia's sake. I just wish they would do the same for the Special Cool Fire and make that one available again.

@nynaevelan I guess your right

@nadoal-alaa-akari Katsumoto along with a few more were re-skinned with armor for when the arenas started. This was before they came up with the skins for the dragons so yes they are exactly the same look. If memory serves they are all in the First Arena collection.

Drummer and Oil Paint

Icewind and Demonic
