Bio

Sealed in the old World

Back in ancient times, a human named Aaron used a staff and sealed a lucario within it to take care of the Tree of Beginnings. Eventually the wicked Sandayu ended the old world, leaving the staff to never be seen again.
The staff was eventually picked up by traveling merchants who sold it to an pawn shop where it remained.

From within the staff, Lucius began to utterly resent mankind and decided to sleep within the staff and plot revenge against them, even Aaron who promised to come back for him, even training within the staff to fight and turn the human he sees into a diaper.

Awakened in the New World

Several centuries have passed and Lucius was planning to give up hope from ever being free. Fortunately the staff was purchased by some nobles in Siwa to offer it as a gift for Mona 1 and Apollo by presenting it to Sol, one of the Elemental Knights of Siwa.
Sol got it appraised by Yuri, where it was really top notch.

As Sol presented it, a pokemon from the old world. The Lucario charged and assaulted a guard who looked like Aaron deeming them 'betrayers' much to the confusion as no one ever heard of that name since the old world's downfall.
The Lucario opened his eyes and was very confused in the world he's in as theirs diapered pokemon were everywhere, some wearing regulars, others wearing other pokemon.

Guards were ready to arrest him, but Sol called them off and wanted to ask him some questions. He only agreed since it was Lucario and he can tell from the Aura he seemed trustworthy.

Joining the Elemental Knights

He introduced himself as Lucius Calisto, that's all he can remember. Asked if he has any friends or acquaintances, but refuses to trust others. Sol didn't want to see a pokemon of his talent and combat go to waste, he figured if his Captain, Arthur Quicksilver could trust a thief, than Sol would trust a stranger.

Sol convinced him to try out for knight as he'd love to have him in the Steel unit. Eventually the royal guard exam came by and Licious watched as Arthur and Sol duke it out. Despite Sols loss, he was promoted to royal guard, seeing how they fought, Lucius began to soften seeing honorable Knights fight for honor of the royal family.

Sol named Lucius his successor as the new Steel Captain, even giving him his former weapons, a pair of scimitars. Sol asked if he wanted to be his Sworn Brother, Lucius decided to agree if he can someday fight both him and Arthur and he always remained honorable.
The two shook hands and decided to spar, and was introduced to the other new Elemental Captain, such as Akira Bursyamo, Eclipse Knight, a Greninja, Daisuke and Grace.

Calisto Family

As Lucius was patrolling the area with his knights, he saw a flier for an upcoming sumo tournament, and decided to attend to learn some new fighting moves to help him.
He saw an empty seat next to a Gardevoir and was smitten by her. The two watched as a Snorlax went up against a Rhydon. Lucius asked her out on a date, which she accepted. Lucius heard good things about a ramen shop run by a tubby Zangoose named Milo.

As the two had some spicy ramen, the two began to fall in love. Several years passed by and Lucius married Rosa. He took some time off as the duo were going to have a son they'd name Ethan, making Lucius smile as now has a son to pass on his Aura and fighting skills.

While Lucius was training and bonding with Ethan, they heard a knock in their door and much to their surprise, they saw an infant Sylveon. Knowing what it was like to be abandoned, Lucius and Rosa decided to adopt her, even naming her Hannah.

Lucius had to return to the knights as he heard about a tomb raid, but he promised he'd stop by at times to spend time with his new family. Ethan said he'd train hard to protect momma Rosa and his new baby sister Hannah.


Siwa Raid

Siwa was being attacked by the Dark Gator Pirates orchestrated by Kroko. Much to his dismay seeing he was looking to usurp the throne. He fought as much as he can against a Kingambit, he was eventually attacked by an Inteleon and the Kimgambit got a cheap shot on him.
They decided to ditch him as they made their way to Yuri's forge.

Badly broken and near death, he decided to find Sol. Sol was horrified to see what happened, Lucius apologized for not being stronger and begged to send Knights to get his family out of Siwa, Sol promised as Lucius gave back the scimitars. Sol immediately sent Knights to Lucius' house, but was puzzled as Lucius' body went missing.

Reborn as a Nobody

His desire to get payback allowed him to summon the Dark Gate from Life's Border. The gate was opened and Lucius would be able to gain new powers if he surrendered his heart to the darkness. As much as he didn't want to, but he couldn't stand that evil won.
As the gate took his body to the Dark Realm, he surrendered his heart, much to his surprise, several of his old allies agreed as well. They all gained new powers and black coats.

Overthrowing the Sand Kingdom

Several years passed by and they had all members ready and accounted for as they staged a rebellion and overthrew the San king and eliminated the magic guilds.
Despite knowing that they framed gum, he was still involved as it showed he was supporting corrupt nobility.
He was hailed as a hero like the others and made the Sand Castle their home and headquarters, he often wondered if Rosa and his kids escaped.

Siwa War

Unlike the other members, he actually took part in the war in secret, such as turning nobles into diapers, weakening the forces, and even freeing the remaining Lugias from being pets and diapers.

After the War

Despite not being involved, he and several other members went to leave black roses on Arthur's memorial statue. Hating nobility even more, he took part in am upcoming prison rebellion, like some of other members, he convinced the Sharpedo Sentries to abandon their post, which they agreed since they detested the prisons new policies and left with the Xatus and Mars Quicksilver.

With more corruption and evil rising, he'd be able to send more hearts to the Dark realm as he targets the Butterfly and hisui where corruption was high and soon to soar.
