Millions and AFO were both important characters in My Hero Academy. They both had great strength and abilities. However, who was stronger depended on character settings and battle strategy.
Million Passers was one of the strongest heroes in My Hero Academy. He had invincible walls and unparalleled strength. His ability can resist all attacks and can reflect enemy attacks through walls. In battle, he usually adopted a static defense strategy to defend against the enemy's attacks by holding his position. Thus, the static defense of a million was very strong.
AFO was another very powerful character in My Hero Academy. He had the ability to fly and teleport. His ability allowed him to teleport anywhere and attack the enemy's weakness. In battle, he usually used dynamic attack strategies to defeat the enemy by moving quickly and attacking. Therefore, AFO was very powerful in terms of dynamic attacks.
Both Million Passers and AFO were very powerful characters. The stronger one was, the more determined the character's combat strategy and settings. Under certain circumstances, the Million Passers may adopt a more static defensive strategy, while under certain circumstances, AFO may adopt a more dynamic offensive strategy.
In most of such fanfictions, they might create evidence like hidden past connections. For example, AFO could be secretly involved in Izuku Midoriya's (Deku) family history. Maybe he had a relationship with Deku's mother long ago, which led to Deku's birth. But it's all fictional speculation within the fanfiction world.
One common plot twist is that Deku discovers the truth about his father in a moment of great crisis. For example, when he's facing off against AFO in a big battle, AFO reveals the truth to him, which completely shakes Deku's world view.
His friends like Ochaco could help. She might use her zero - gravity ability to assist in handling heavy parts during the construction. Also, Iida could be there to keep things organized and on schedule with his strict sense of order.
All Might often appears. Since he was Izuku's mentor, in time travel scenarios, he might be the one Izuku turns to for advice or assistance. Another common character is Bakugo. Their complex relationship can be explored further in time travel stories, like if Izuku goes back in time, he might try to change how Bakugo treated him in the past.
There could be his friends like Ochaco Uraraka. She might be in a position where she's trying to understand Izuku's situation and help him. Maybe she tries to convince the people forcing Izuku to give him some space.
Ochaco Uraraka could also be a common pairing. Since she has her own insecurities and dreams in the hero world, Izuku's reality - controlling power could play a role in either helping her achieve her goals or creating new challenges for their relationship. For example, if Izuku accidentally changes something in reality that affects her family's financial situation, it could impact their relationship and how they interact.
Bakugo is often paired with Izuku. Their complex relationship from the original series can be further explored in fanfiction with Izuku's growth quirk. All Might is also a common character paired with Izuku. He could play a role in guiding Izuku to control and develop his growth quirk. Ochaco is another one. She might be involved in stories where Izuku's growth quirk affects his relationships, especially romantic ones.
All Might would probably be in it. Since he's Izuku's mentor, he could play a role in helping Izuku understand and control his time - controlling power. Maybe he has some past experience related to time powers that he shares with Izuku.
In many adopted Izuku fanfictions, his character develops confidence. For example, if he's adopted into a loving family, he no longer has the self - doubt that plagued him before. He starts to believe in his abilities more. This new family support gives him the boost he needs to train harder and become more assertive in his hero journey.
