Maximus Boltagon Junior
JBL
Three year old Max woke up in a crater to see five kids in solid color rain coats, 5 JBL members, around the crater. The one in the green coat in the middle said "Who are you?"
Max's mind quickly deciphered the words based on the five kids' body language. He answered "Max. Maximus Junior."
"Max, eh? I go by Whirlwind. Let's get out of here."
Normally a JBL member names a candidate. Then the candidate has to be approved before they're investigated by another member to ensure the organization doesn't get a spy. JBL legend Vance Creed was a trained spy by 5 years old, trained by Jericho to be the CORE's Ravager. After the investigation ensures the candidate's capable of handling life drifting from place to place and completing missions as a JBL member, the pending member is approached by a member in the role of recruiter (Aaron Kile, a sponsor, investigator or random member). Initially the member will be tasked with handling the drifter lifestyle of a member, going on occasional small missions and standing up for people as they wander without standing out, being a heroic person without being a superhero. As they move up the missions become harder and more important. Vance Creed set a record by completing dozens of difficult missions within his first few months in the JBL after leaving the CORE, he was even named an advisor to JBL founder Aaron Kile.
Whirlwind joined the Jacket Bearing Legacies before they were the JBL, at their founding when they were a legacy network running from the government's Legacy Control. The recruitment process then was a few simple questions. Can you control your legacy ability? Do you want to help others escape Legacy Control? Are you willing to risk your life to save legacies? The process was expanded upon because SHIELD and other government entities took an interest. For Max, Whirlwind bypassed the normal channels to get him in that day.
Max's JBL jacket is black. Whirlwind's jacket is green because David Cannon (Whirlwind I) wore a green costume.
Sadly everything Max owns fits in a small backpack but he never minded. Most of his work was infiltrating New Generation villains' networks to prevent them from achieving A-List levels of infamy so having a lot of stuff is counterproductive. In between missions the JBL put Max in safe houses to relax and sleep.
According to quick research Whirlwind did, geniuses reportedly obsess over experiments to the point of neglecting sleep for days. Max never gets 8 hours sleep a night in safe houses. Even when he was locked in a house's master bedroom suite without TV or anyone talking to him for two days. He didn't go stir crazy but he didn't sleep as much as recommended.
