Batman

When Allen was reborn in Gotham and awakened to his belief system, the first thing he thought of was to cooperate with Batman. As for the price, it is to become Bruce's biological brother, with endless money to spend every day. All he has to do is to abandon his brain and work hard to achieve miracles. "Bruce, give me some money, these believers are so materialistic." "Bruce, I need equipment, someone is robbing me of my followers." "Bruce, give me some kryptonite, that Superman guy actually questioned my identity." "Bu..." "Don't bother me. Find everything on the table yourself." Batman's veins popped out. If Allen hadn't helped govern Gotham and protected the world, he would have had a fight with Allen no matter what. Wait until the whole world and even the Marvel Universe believe in Allen. "Bruce, I can resurrect your parents now."
