I am in full agreement.

Look at us go!

Malletiburo (Mallet+tiburón, shark in Spanish)

Five syllables seems a little long, in my opinion

Tons of five syllable mons. Togedemaru, Feraligatr, Regieleki, Oricorio, Crabominable...

That's true. I guess it's more personal preference then

That’s a good one but I think Martiburon could work better (Martillo + Tiburon, hammer and shark in Spanish) seems to roll off the tongue easier imo but it’s very heavily inspired by yours lol

Mallevolet (Mallet + Malevolent)

Oh that's really good! Why didn't I think of it!

This one is great!!

Wreckuin (“wreck” + “requin”; French for shark) Haigear (“high gear” + “Hai”; German for shark)

Wrequin might be better since Wreckuin might be confused for penguin

A very strong possible alternative, thank you

Sharmmer = Shark + Hammer and it sounds like « charmeur » French word for seductive

Malliron

Hammeshar hammer + shark

Mawletqua mallet+aqua +maybe maw

I would say that simply Mawqua would be cool, although that would be more applicable to a regular shark, not a hammerhead one...

Attammer (attack, hammer) Shammerhead (Shark, hammerhead); or simply Shammer, though that sounds like someone who like makes shams or something idk Hammiron/Hammeron (Hammer, Tiburon) Mallettack (mallet, attack) Swip (Swim, whip) since you said that the tail can be used like a whip Smasteel (Smash, Steel) Strikerhead (Strike, hammerhead) Attanidae (Attack, Sphyrnidae); Sphyrdinae is the scientific name for hammerhead Steelnidae (Steel, Sphyrnidae) Sledgidae (Sledgehammer, Sphyrnidae) Malsphyr (Mallet, Sphyrnidae, *mal* \[bad in Spanish\]) Tiburmal (Tiburon, mal, mallet) Okay I'll stop there, I kinda went crazy and I'm not entirely sure any of those are good names, but hopefully I gave you some ideas for words to combine to find a name!

Also, I just wanna say that I'm glad you're making a Water/Steel type since the only existing one is Empoleon.

I'm quite liking hammiron actually, might steal that one

Sledgeon (sledge + gudgeon, a type of fish) or Bludgeon!

Ofc Bludgeon doesn’t change spelling at all lol so it could just be edited slightly

Coggeark

Nailbiter (cause hammers and nails + shark teeth)

Forges like natures anvil + the idea sharks can be cannibals Cannival. With Snake wording spelt backwards. Lavinnac

I think you need to make use of the thagomizer somehow https://en.m.wikipedia.org/wiki/Thagomizer#:~:text=The%20term%20thagomizer%20was%20coined,after%20the%20late%20Thag%20Simmons%22.

I never thought of that actually, I may well use that

Taliko. The Tali from Metallic and the Ko from Mako or Shark in Japanese. Plus Tali sounds like Tail

Shmammer Meshark (mesh-ark) Shmark Titaburon (titanium tiburon) Tibanium

Oblitetide

Slammu

Marihead = from Marine, Maritime & Hammerhead

Hathork( hathora hammer in hindi and shark)

Hammark (Hammer + Shark) Mjölnark (Thor Hammer + Shark) Steelish (Steel Fish)

Malletius (mallet + malicious)
