Spell My Name with an S/It Is Pronounced Tro PAY: In Japanese his name is written as ルエミーザ (ruemiiza) while his name is always written in English as Lemeza. Does he use a different name depending on language or is Lemeza meant to be pronounced like "ruemiiza?"
Wholesome Crossdresser/Creepy Crossdresser: Up for debate if he's creepy about it or not. Mulbruk and Xelpud are significantly weirded out, but Lemeza himself has absolutely no problems donning the skimpy swimsuit from Hell Temple and workin' it. All the official art showing him in the thing has him happy as a clam, to boot.
Shorn/Shawn Kosugi (ショーン 小杉, shōn kosugi)
Father of Lemeza. He sets off the game's plot by discovering the ruins and taunting his son about it.
Expy: Of Henry Jones, Sr. He also has a touch of Belloq in him, with the whole poaching research thing.
Hero of Another Story: He spent much of his life trying to find the ruins, and he managed to explore them almost entirely. However, because the story is told from Lemeza's POV we only know tiny portions of his tale.
Ninja: Had the same training Lemeza did, and has had longer to perfect it.
The Unchosen One: His final message to you on his computer, which you find at the very heart of the ruins, says that he went through all of the same trials and traps you did and reached La Mulana's heart, but ultimately wasn't able to continue because he wasn't chosen by the four Sages.
The Elder of the village, and the guy who saves your game and generally chats to you.
Badass Grandpa / Hidden Badass: In the remake. Remember that one puzzle where you have to get Shorn's diary, involving that falling pillar? in the original, you use the time lantern. In the remake, you talk to Xelpud, and he literally comes down to that room in the ruins, JUMPS IN ITS FALLING PATH, AND THEN LIFTS IT UP FOR YOU TO GET PAST.
Warm Up Boss: Especially in the original, where a good shuriken spam was his downfall. He's only marginally tougher in the remake. Considering he's usually the first boss a player fights, it's almost like NIGORO wants to lull the player into a false sense of security...
Sakit (サキト, sakito)
A Giant who wished for The Mother not to return to the sky
Collapsing Ceiling Boss: Everytime he takes a step or fires his fist into the ground, rubble falls from the ceiling.
Golem: All the Giants are preserved as huge stone statues. Most of them can move depending on what the time of day is (it's a puzzle, you hit three stone lanterns to change the insgnia so their all either star, sun or moon). Sakit can only be fought when the Moon is showing, unless you sequence break so much that you get the double jump before fighting him.
Bad Boss: In the remake, after the pair of imps have his eye held completely open, Viy will either thrust his eyeball upward, knocking the imps away in the process (often right into you), or disintegrate them with his Wave Motion Eye Laser.
Eye Scream: You hurt it by attacking it's giant eye. And it can attack by everting its eye, trying to stab you with it.
Bullet Hell: Actually fires a lot of bullets even in the original game. It gets even worse in the remake.
Difficulty By Region: Sort of. In the Wiiware remake, it was possible to fly right up in his face and kill him with only a few hits of the flail whip, as collision damage with Palenque did surprisingly little damage. In the PC version of the remake, however, Palenque has a fast life draining ability similar to Viy if you touch him. While this was mostly done to discourage cheap victories, it also makes his battering ram attack do a seriously large amount of damage.
Reality Warper: She changed the sides of her part of the Ruins round. That's right: The Endless corridor is actually the BACKSIDE AREA of the Dimensional Corridor.
She also disables the Holy Grail's power while Lemeza is in the Dimensional Corridor, though he can still teleport into the area.
Slasher Smile: Does this in both versions of the game. As you do damage to her, her facial expression twists into a horrific grin.
The Mother (聖母, seibo)/Mother's Soul (聖母の魂, seibo no tamashii)
She's the creator of all sapient Life, who is unable to get back to the sky. Unfortunately, it's a genuinely impossible task, and she's utterly unable to acknowledge that possibility. The entire plot of the game is to put her out of her misery.
Mother of a Thousand Young: She personally created everything you run into, and it seems like if humans imagined it at all—not merely myth and folklore, but as Viy, the Snouters, and Backbeard attest, even recent literature and pop entertainment—there's some sort of template within her that the idea ultimately emanated from.
One-Winged Angel: Her soul has four forms and her head can be counted as a fifth.
Resurrective Immortality: Mother is immediately reborn if she dies, so the player must give her soul a physical form and kill that.
You Have Failed Me: Constantly happens whenever she comes to the conclusion that the current sapient race is unwilling and/or unable to send her back. It's implied that she does this in part because otherwise there won't be room and/or materials for the new attempt at creating rescuers. One wonders what would happen if she were somehow convinced that she can't get back in the first place...
The Boss (ザ・ボス, za bosu)
He is found in the Hell Temple, a big blue blob with eyes closed and a tongue sticking out that guards the last rooms.
Ascended Extra: In the WiiWare version The Boss uses an unused music that was never used in the original game, Good Morning Mom.
Author Avatar: He looks like the avatar that Naramura typically has.
