The age of the character named Albedo depends entirely on which fictional series you are referring to, as there are prominent characters with this name in the Ben 10 franchise, Genshin Impact, and Overlord.
Albedo has physical appearance has changed throughout the series from a ten-year-old kid to a sixteen-year-old teenager. However, he retains some recurring characteristics.
We know that if the albedo is from Khaenri'ah, then he has to be at least 500 years old, as that is when it was destroyed. This is not nearly old enough to be referred to as ancient in a scientific sense, as he would have to be around 1400-1500 years old.
Albedo is a Galvan who created an Omnitrix which got linked to the original making Ben's DNA the default. Later after a fight with Ben he became an Albino due to the watches cores touching.
Despite being a succubus and her lustful desire, Albedo is surprisingly a virgin.
She lost it to Matt, it was mentioned in the show. Caroline said that they were each other's firsts, but first loves or first you-know's or both is the question.
Ainz was angry at Clementine for killing the Sword of Darkness members whom he had grown fond of. During their short confrontation, He killed her in his true form with a bear hug-like attack.
Albedo is autistic, and has autistic traits. He is someone who often speaks little, he mostly focuses on his work as an alchemist. He is curious about learning more, and studies the art of bringing things to life.
Actually, I forgot who said it, but I think the creators said Anodites just don't have DNA for the Omnitrix to scan. Which is why Ben, Ken(Gwen's brother), and Gwen's father didn't inherit any Anodite powers. The reason why Gwen has it is because she has "the spark" according to Verdona.
Albedo appears as a boss on MorOtesi tricking Cooper into making an energy core from Taydenite. All of his aliens' eyes and Omnitrix symbol are red.
Qiqi is technically hundreds of years old. Age before death is unknown, but clearly a child.
Hence, her name was red-tagged, and Albedo reported her as a rebel to Lord Ainz. Ainz engaged Shalltear in one-on-one combat to change her settings. After resurrecting Shalltear with 500 million gold, Ainz was able to restore her to her former self. Albedo, likewise, did not betray Ainz.
In case you're completely dense, this isn't an Omnitrix, either. It's something to stabilize my transformations. And once I have the final component, I will achieve ultimate power! Albedo, explaining the purpose of his new device. The Ultimatrix [ms 1] was a device created by Albedo, based off his original Ultimatrix.
Ainz Ooal Gown
As such, Albedo is completely infatuated with Ainz and is absolutely loyal to him. Even when he tells her that she only loves him because he made her that way, the only problem she has with it is if it causes him trouble.
The bond albedo is the fraction of radiation hitting an object that gets reflected. If 100 joules of energy hit an object and the object reflects 71 joules, then the objects bond albedo is 71/100 or 0.71. Naturally the bond albedo can never be more than 1 as an object cannot reflect more energy than it receives.
Although only female Anodites have been seen, males "sort of" exist. This is evident by the fact Verdona always hoped that her sons and grandsons would have inherited her Anodite powers.
The title of Ben 10's darkest episode is often debated, but "Catch a Falling Star" from Ben 10: Ultimate Alien is a top contender due to its themes of Stockholm Syndrome, graphic violence (including murder), and genuinely bleak atmosphere, while other dark moments include Kevin's descent into villainy in the "Ultimate Kevin" arc and the psychological horror of "Ghostfreaked Out". Other episodes like "Max Out" (Grandpa Max's sacrifice) and events in the "Alien Force" series also feature intensely dark and mature content.
Cause She is not fully an anodite and it takes 65 some years to master her anodite powers. Because Gwen's not technically an Anodite, she's a human with an Anodite “spark”.
Due to her nature as a succubus and how she was programmed by Ainz to be in love with him, Albedo is quite assertive to a fault. She sometimes loses control of herself around what Ainz says to the point of going to extreme actions, such as almost raping him against his will.
Extremely loyal and in love, Albedo is infatuated and needy/clingy with Ainz, often showing obsessive tendencies when it comes to his affairs. She is always vying for Ainz's affections, showcasing outbursts of jealousy whenever anyone else appears to be getting close to him.
So Albedo is Klee's brother through adoption as Alice was Albedos master and somewhere in the lore she states Albedo being "like a son" or "to call her mother not master" (came across this in a youtube comment thread). Alice also has ties with Mona being friends or something with Mona's master.
Ultimately, the Overlord was defeated by Lloyd and the combined elemental might of Earth, Fire, Ice and Lightning, which took the form of the Golden Ultra Dragon. With his physical vessel destroyed, his material being returned to dormancy while his ethereal being awaits the day he takes form once more.
Shalltear is completely loyal to Ainz and is also considered to be the love rival to Albedo for his affections. She takes great joy in being able to prove her worth and fantasizes about the praise she expects to receive from Ainz.
Dekatsuyo took over the body of the real Momonga. This is confirmed multiple times throughout the anime and the manga. Examples are Momonga attempting to eat Chiikawa like how a chimera would in Episode 270, and the current Dekatsuyo having a dream about finally returning into their true body.
