Iron Doll & Browny?

Well, they have big shoulders and a horn on their heads!
They both sling a long, mean weapon.
They check out okay.

Headless dude from Altered Beast & Headless Swordsman!

NO question! This head carrying zombie from Altered Beast reappears in Super CastleVania IV!

Count Dracula 2nd Form & Contra hard Corps Alien Cell!

A nasty clump of bleeding heads...yes, it counts!

Sonia Belmont & Akagi Ritsuko?

It's as close as comparing Hyenas to Lions, which both belong to the cat
family, but I think this one's okay if you asked Ritsuko, Evangelion's science lady on
the right, to grow her hair long and make a pony tail of it.

Richter Belmont & Nephlite?

If you watched that one Sailor Moon episode, "Worth a Princesses Ransom" (?)
Nephrite is sorta dressed up like the new style Richter.

Sandalphon & Anomalocaris!

Pardon me for being CastleVania irrelevant; blame the Evangelion groove..
Eva fans! The Angel from the Magma Diver episode (Sandalphon) is designed
after this prehistoric killer of the Paleozoic oceans, 700-500 million years ago.

Alucard & Seltzer & Se4oth?

Hey! Look! Alucard DOESN'T look like Seltzer from
Ultimately Last Fantasy 23, NOR does he look
like that saddie Se4oth from Ultimately Last Fantasy 927!!!

Dracula & Skull Shield beast!

Anapan has noted that the above cluster of Skulls you see when you do a Skull Shield
spell in Symphony of the Night looks just like Dracula's 2nd CV3 form, when you
destroy a head, that is. He even made this animated picture of it! Thanks, Anapan!

Legion & Contra Hard Corps Alien Cell!

Vic Rattlehead has pointed out that CircleVania's Legion
really does resemble the Alien Cell mutation!
