Wilbur Macrothorax hatched on the 14th July 1985 in Mepolis. He's the middle child to Lawrence and Sylvia. Will was alright as a kid, he was rebellious but in a sneaky way but always presented himself as timid to others. He doesn't know if he did this intentionally due to his personality or if he was truly that shy. Wilbur also hated his appearance for some reason and never wanted to be photographed, he always had his teeth bared in any. Will and Marshal were long time friends since he was 4. Marshal and Will met in kindergarten. When Will’s brother Shrike hatched in 1989, he hated him immediately and was very jealous of the attention Shrike got. Wilbur was diagnosed with ADHD in march of 1992 (mostly fitting the inattentive symptoms) and till his death took ritalin. Wilbur was inconsistent in taking this drug in the first few years. The effect this drug had on him wasn't too good. It may have made him improve executive functioning but it left him constantly drowsy and nervous. He also had trouble eating. Lawrence introduced Will to rock skipping when taking Will fishing with him.

Will always had a fascination with projectiles, guns and ragdoll physics. He started taking this hobby seriously by buying airsoft guns and doing targeting outside his house. In school, Wilbur started an interest in all things physics and chemistry related. He frequently stole chemicals from school without being caught and used them in trial and error experiments at home. Victor moved to Will’s school in Sep of 1997 and they became friends. Wilbur's personality during puberty took a shift to the worse. He became brazenly callous and borderline sociopathic. Many in school didn't like him due to his covert narcissism. Some would say that he's impossible to bully as he always came up with something 10 times worse as revenge. Wilbur was over-exposed to the internet and stumbled upon stuff he shouldn't have at that age. He became addicted shock content and gore and would brag about being desensitised to classmates. He even challenged them to watch some videos without looking away to appear tough-skinned and badass. This worked but he became known as that one edgelord creep. On the 26th april 1998, Wilbur got a giant snail pet and named it Peppers. Connie took a liking to him in September of 1999 and asked him to date in chemistry class one day. Will never liked her but decided to try it out for the experience. Due to this, Will was coerced into stuff he regretted doing.

Wilbur even began email scamming people in 2000 as a side-hustle. It was moderately successful and he used the money for airsoft gear. One time he scammed someone $45 only for Victor to come crying to him saying he was scammed. Wilbur realised it was Vic he accidently scammed and returned the money but never admitted it was truly him. Despite this he still continued scamming. In April 2000 his school hosted a science contest. Will conjured up a type of glue that closes wounds very quickly and stops bleeding. In the making of the prototype he tested it on live rats. During the actual contest he asked for volunteers but after no one wanted to be one he cut his upper left arm and tried it on himself. The glue worked a little but left a scar. When Vic and Will went to Utlan over december 2000, he skied on the first day but then switched to snowboarding just to mess with Vic. After Vic and Will mated and Vic layed their egg, Wilbur was quite annoyed at Vic pestering him about their miscarriage when it happened. Wilbur never liked babies and never wanted kids ever. Victor kept trying to convince Will to marry him and start a family even though Wilbur told him plenty of times that he didn't want to. Vic also got frustrated seeing Wilbur's unempathetic reaction to their miscarriage. Wilbur was secretly still pissed about Vic's baby obsession but after seeing him be so miserable for a month he decided to make their relationship official. He did this mostly just to make Victor cheer up. Peppers the snail died naturally in March of 2001.

Wilbur's twin siblings hatched on August 6th 2001. He also wasn't a fan of them, especially that his parents made him look after them. Victor however loved them and always made time to see and care for them. In september, Vic and Will got caught hugging when Shrike peeked through Will's bedroom window. He snitched on them to his dad but Lawrence brushed it off and said it's just them being friends. Shrike continued to stalk them and on the 19th Sep saw them mating. Will and Vic thought they were alone in the house. Shrike confronted them and threatned to tell his dad and Vic restrained Shrike and Wilbur begged him not to tell. Vic started crying. When his parents came back, Shrike snitched to his dad but Will claimed that he was making it up in order to get Vic kicked out of the house as they hate eachother. Lawrence didn't know what to believe so he trusted Will's claim. A week later, as Vic was saying bye to Will before leaving Will's house, they kissed but it was all caught on video from Shrike hiding and secretly taping them. Shrike showed this to Lawrence and he was so livid. He demanded that Vic be banned from the house and that Will wasn't allowed to see him at all. Lawrence visited Randy to tell him to comply with this. Randy reveals that almost a year ago Vic layed an egg that Will was responsible for. This fiasco dealed a blow to Will and Vic's relationship. Wilbur was punished in the form of conversion therapy. Instead of meeting inside, the pair met up outside and mated in odd public areas like in forests and beach sheds. Wilbur was getting stressed out over this change and was more paranoid over knocking Vic up..

Wilbur got his scar on his snout from a sulphuric acid burn in 3rd Sep 2009. It was concentrated and left him permanently scarred.
