Age: 17
Height: 170cm
Weight: skinny????
Medical Info: YO SPOILERS. He's a genetically engineered child created out of very specific DNA strands. A hybrid human. So he's a little stronger and quicker with his reflexes than a normal person. And Ren is dying. A genetic defect causing apoptosis - cell death - will have him lucky to reach 18 in canon. A drug called Raphael could save him, but its development was canceled (to his knowledge). Transforming into Ultraman hurries his death along.
Eyes: brown
Hair: reddish-brown
Physical Traits: Likes wearing baggy shirts and jackets. Nothing out of the ordinary. Except when he transforms into a giant silver/blue being of light that fights monsters.
What's Okay To Mention Around Him/Her: Ren is being taken from before episode 33 so . . . don't spoil him. But feel free to fourth wall him in other ways..
Abilities: Canon was a little fuzzy on his ESP powers, but things that were confirmed he can do: astral projection, rectrocognition (ability to see the past of an event or object), possibly precognition, and telepathy. He doesn't go out of his way to use them. He carries a gun that shoots rays of light and deals one K.0. hits for smaller monsters. Using the Evoltruster (sob), he can transform into Ultraman Nexus and use the Anphans and Junis Blue forms. As Ultraman, his abilities are . . .
look here. ALSO IT'S CANON THAT HE CAN CONTROL HIS SIZE. ILU canon. So he doesn't have to be 162/164ft tall. He just usually is.
Notes for the Psychics/Magically or Spiritually sensitive: Happy, cheerful thoughts for the most part. Maybe an edge of worry here and there. I'd imagine he'd have some blocks for his deeper concerns, since even he tries to forget about them. His bond with the light remains on the downlow because even his even more powerful psychic friend couldn't sense it until Ren outed himself.
Can I shapeshift/bodyswap/spit at/step on/etc?: Spit at and step on sure! Though you'll make Ren very confused and maybe sad. Ask first about the others?
Hugging/kissing/other non-violent physical contact: Go for it!
Maim/Murder/Death: A little maiming is okay. Murder and death . . . there should be talking.
Cooking: He probably could if he tried. He can make little cakes and takoyaki! But really, he is a 17-year-old boy on his own. He probably lives off of instant noodles and who knows what. (If you feed him good things, he will love you forever.)
Other: Concerning Ren's condition, his personal time will be halted for camp so it doesn't progress that way, but he doesn't know that yet. If he transforms into Ultraman . . . well, there are always moogles, right?
