Pararoh Kyosuke The Zekrom: His life used to be basic. Much like a sinnohan Born Zekrom. (He was born in Sinnoh region.) He isn't a typical Zekrom. As his body sports Dialga ancestry. (His grandfather is a Diagla.) His best friend Poseidos. (Who is born in Alola.) Along with his beloved girlfriend. (now one of 5-6 wives.) Yoko the super timid Miraidon. (She had ate a mint to get the bold nature effect. But she is still super timid at heart.) Gaea the Gaikia. (Poseidos's wife.) And a crew with a Tour guide Otogi the thick and obese Lunala gal. to an Ancient civilization in the desert of eastern Indieo region.
They were convinced to go inside the Pyramid (Which is illegal. But that was due to professor Tsuchida the Arceus. and A Medic Cobalion Kuroe. (Thou it was Tsuchida that dragged the crew into this mess. A series of misfortunes had occurred. of all the crew members. 3 perished. 1 was preventable. But Poseidos forgot about the Fatty Darkrai due to too much crap going on. Leaving the Darkrai fatty to perish in the gas chamber...

Everyone else was judged and attacked. But Poseidos saved them all. (Even himself at the beginning for pushing a mummy into the water out of desperation to lower the cargo of the sinking boat they were in...

As time went on. Poseidos saved his beloved Gaea from being trapped in a coffin. (She was judged for jealously. Due to Yoko panicking and hard hugging Poseidos. Thinking she was the next one to die. (Which she was attacked by a Zacain Egypt statue now gone alive. Poseidos almost died from this encounter. But pulled the necklace off of Yoko's neck and threw it into the pile...Saving her life. (She was judged for being a thief.)

Everyone was judged of their crimes/sins. All but Kyosuke.

At the final destination. Poseidos finds Pharaoh Khufu. Leaves to get the crew. And Things go nut. Khufu is STILL alive. (for being a human to live for 5k years....)
This even gets Tsuchida going WTF?! Later after explaining more with the Ritual to become a god/goddess. Tsuchida gets pissed with Kuroe about HOW is he not judged. Poseidos Interrupts with. "Tsuchida! Sorry but He was judged! He was a thief for stealing all that gold." Even then. The Arceus professor shoots and kills Kuroe.
The crew was in shock...
Tsuchida explains on why he killed Kuroe? He failed to save tsuchida's daughter. (Granted Kuroe was not yet a certified doctor...Else he would lose that chance for a violation and thus, never become a doctor...)
The Pharaoh Khufu gets up and uses his powers to Crush Tsuchida's spine with a pillar. As the professor is caught and judged for the audacity for being a Murderer.
Poseidos, Gaea, and Otogi the Lunala (Tour guide.) Attempts to move the pillar off of the broken Arcues...before another is thrown down. Killing the Professor and sending the 4 (Rin is a shiny young Koraidon.) to the flour.
This is when Kyosuke the Zekrom. was then pulled to the pharaoh. Being worthy of becoming the new god. (Kyosuke had lied before. But mainly to comfort his friends and his lover. not enough to be judged for any crime.) Cause of not having ANY SIN! He was then Electrocuted. (Powers passing into his body.)

Poseidos and 4 allies. fight to defeat this Pharaoh. they killed him. (But Poseidos sure felt guilty as hell...He did the killing blow.)
Kyosuke reassured Poseidos that. "The Pharaoh WANTED to die. Being alive for 5k plus years. At that point. You would go insane for living forever...Think of it this way. You have finally freed him from his personal hell!"
Then the Pyramid starts to collapse (This was due to Kyosuke thinking the place will fall apart. Not knowing he is the new Pharaoh!)
The crew runs away. Only for Poseidos to get dragged down by the now dead Fatty Darkrai. (Zombie at this point but also due to Kyosuke freaking out. and movies he watched.)
The Darkrai gets his head smashed with a boot to the face. (Stepped on to get out of there.)
Soon they reach the final escape spot...Things look grim. But then Kyosuke talks about Moses with the ability to split the water in two to leave a pathway to escape.
WHich by chance....OPENS!
Poseidos then...Finally tells Kyosuke...he is the new Pharaoh. At first he was WTF are you smoking man?!
But over time. Kyosuke does get suprised. (even able to levitate Poseidos's Bandana.)
Which then Poseidos orders Kyosuke to think of an ideal place. use that Pyramid to transform into something he desires.
Calming down...he thinks hard...and the Pyramid transforms into his VISION!!
Now with a new life and responsibility. He is a happy Zekrom young man. Enjoying his newfound powers!

As for Poseidos the evolved Gyarados?...He was never carefree again. (Mainly due to witnessing a lot of dark stuff.)

The reason why Pharaoh Kyosuke is pretty chubby? It is due to an incident of an Fakemon. Paldean Gaikia. Since then. He is working on to get slim once more. It is going to take a while. More so with Yoko finding chunky Kyosuke cute.
