Megami Nagareboshi/Tropes

A-G
Big Bad: Honestly, Megami could very well be this. While having "heroic" vibes, she's far from kind to the heroes, going around brainwashing the effiminate ones that she likes, and she shows a much darker side to them.

Boobs of Steel: Largest breast size of any female Nagareboshi family member (not that there is anyone to currently compare to, with the only female members being Lolicon age at the moment), and possibly the largest bust size of the current cast, matched or outmatched by Kaede, and is second in power only to Kaede.

Fiery Redhead: Averted. Despite her crimson red hair, she is fairly level headed, even in battle.

H-P
Harem Heroine: And I use "heroine" very, VERY loosely. While she has never been outright malicious, inflicting And I Must Scream onto various effeminate boys is far from heroic, but her actions against Kaede cement her here.

Icy Blue Eyes: To go with her bright crimson hair.

Incest Is Relative: Has no real problems with it.
 * Brother-Sister Incest: Masato is confirmed by Word of God to be her brother....through an exceedingly complex method.
 * Incest Subtext: Despite wanting it, she never acts on it with anyone other than Masato.
 * Parental Incest: Wanted to add Gai and Kachihi to her "collection" for awhile.
 * Villainous Incest: Initially.

Meaningful Name: Her nickname translates into "Little More Than Wicked", which fits perfectly well with her initial betrayal was a sex-slave holder. Her actual first name means "Goddess" and it is befitting of her level of power, which allowed her to fight evenly for awhile with Kaede, and this is without a Zanpakutō.

Like a Son to Me: She seems to think this way about Kachihi Amagase, who, in all honestly, needs the attention considering both Gai and Mitsuru's lack of any real parenting to the boy.

Mama Bear: Threaten her children and she will whoop your ass.

Power Limiter: Subverted, she can enhance abilities with her magic.

Q-V
Squishy Wizard: Magnificently averted, this woman has the durability of a couple of tanks, and the strength of a few gods.

W-Z
Wave Motion Gun: Like the rest of her family, she is able to use the Shining Onslaught, however, her's requires a Magical Incantation to be at full power, therefore functioning like a Kidō.
