Probably a bit late ti this but - spidersona!

They are called spider one - oh and were bitten by a cellar spider aka a daddy long legs spider.
When they woke up after being bitten, their limbs had grown to an abnormal length. They didnt really mind this, but it did mean they were too long for their favourite hoodie so they had to cut the arms and add inserts so they fitted.

The actual person behind the mask is genderfluid but since its hard to keep the press up to date on their daily gender swaps, they just didnt bother confirming their gender. This has lead to several reporting agencies arguing over the correct pronouns to use but one oh finds it amusing and refuses to tell anyone their pronouns. They do have a mask but it messes up their hair and is too slippery for headphones so they tend to go around with only the bottom of their face covered and save the mask for public appearances.

one oh likes messing around with computers so thats where they got their name.

the chevrons on their suit are based off actual cellar spiders which have chevron looking bits on their knees (? knees sound weird for a spider)
