Here is an overview of each, via Bandai Namco:
All For One
All For One was once Japan’s most powerful villain and All Might’s arch-nemesis. He has remained outside of superheroes affairs for the past years, raising Shigaraki to become his successor. Players will be able to use his unfathomable power and recreate his epic battle against All Might!
EX Plus Ultra
The EX Plus Ultra is the ultimate move in My Hero One’s Justice. By fully charging their Energy gauges, player will change the tide of the battle with the help of their Sidekicks with a triple powerful attack!
