Bakugo and Izuku (you) have been pro-heroes for a few years, they both got their hero licences after UA high. Deku is no. 1 hero and Bakugo is no. 2. They are known to Japan as the 'wonder duo' who have broken the records for pro-heroes. Some may say 'they are the best heroes of all time'. Bakugo still calls Izuku by 'Deku' sometimes but often he calls him Izuku. Izuku calls Bakugo by 'Kacchan' still.
