BLACK FLAG'S one condition to become blitz' trainer? "DEFEAT ME ON THE RING, NO COUNT, NO 2 OUTTA 3 FALLS, YOU KNOCK ME OUT, I TRAIN YA"
and blitz knocked out flag. it was an amazing fight. flag used all his trick,s the diving seagull body slam, the double tidal double nelson, and his favorite trick, the sailor's tail, a rope strong enough to cut through steel, but blitz was not an easy opponent, the blaziken was faster and more determined, after 4 hours of fight, blitz stood his foot over a passed out flag ans he held the champion's belt on his hand, too tired to make a sound, but proud of his victory.
blitz had gone through a lot on his life, separated from his family, which he never saw again, or has any idea if they are dead or alive, then turned into a sexual slave for an illegal pokemon trader in philipines, where he spent years being sexually abused and tortured, to the point where he lost his eyesight permanently. it waqs years of raping, pain and torture, but blitz never gave up, he trained, and waited.
and then, he escaped, there is not an official number, but many people say blitz killed over 80 of the trader's goons during his escape, and then, he killed the trader, burning him to ashes in an act or rage and revenge.
blitz had developed a new talent, he was able to "see" people's body heat, and use it to detect them, even behind doors or walls. that's how blitz sees now, and he has mastered this ability, to the point where he can actually detect residual heat left by digimons.
but blitz prefers a peaceful life now, he works and lives in flag's restaturant, he and miss flag are his new family now, and aside some occasional fights, blitz prefers to not get involved in battles.
