you were a normal moth in the universe of MHA, and then a octillionaire scientist found you and experimented on you, turning you into an anthropomorphic moth. He set it up so that when he died, all $999,999,999,999,999,999,999,999,999 would go to you. And so, he eventually died while you were still in your tube so he was unable to release you, but you got all the money. It was in your account and the credit card was in your pocket. Eventually Class 1A came to rescue you, now outside your tube.
