Disclaimer: I am right! Hori I hope you have my post notifs on. I have figured it all out.
Dabi is an ambiguous character in BNHA. He has an A, or 5/6, in mystery, and we know nothing about his interests. Dabi could be anything, so I have come to the conclusion that he is in fact a time traveler.
When Dabi introduces himself, he say he “currently goes by Dabi”. This implies that he has multiple names. Some say one those names might be “Touya”, but Touya could be one of many names he has used over the past couple of centuries.
With all of the previous OFA users, we see that one of the users has similar hair to Dabi. This could be Hori only drawing 4 types of hairstyles, but maybe Dabi held OFA. How did he do this if this user lived so long ago? I have the answer. He time traveled.
Dabi has used his time travel techniques a few times within the plot of BNHA. How did the League of Villains know where the Class 1-A summer training camp was? Well there was no traitor, but instead a time traveling Dabi who went into the future to know where Bakugou would be.
During the war arc when everyone else is running in one direction, Dabi instead runs in the opposite direction towards the Hawks and Twice fight. How did he know this? Easy! He time traveled and saw the future.
Another instance is how does Dabi know Endeavor and Hawks’ names? Yes he could be Endeavor’s son, or Hawks’ former former, but instead I think he time traveled into the past to learn their names.
The first use of the word “endeavour” was in the 14th century. Dabi is known to say the hero name Endeavor in canon, so he may have been alive during the 1300s. This means Dabi survived the Black Plague.
If we wish to go back further, when Dabi is fighting Geten he says “ice melts”. He would he know this because he was alive during the Ice Age, and he witnessed the melting of the Ice as the Earth’s temperature rose again.
So how can Dabi time travel? Is it a quirk? No. He has a C in intelligence, so maybe he cannot explain how he can time travel. It is all instinct now. Or possibly, Dabi could explain it in a language unknown to the characters currently in BNHA.
Maybe Dabi knows a language so ancient and primordial. That he why when he answers Hawks’ question about who he is, we are simply left with a black speech bubble. Hori did not know how to translate Dabi’s native tongue.
Dabi’s age is also unknown. We only know he was born on January 18th, so he really is just a Capricorn causing chaos. Maybe we cannot fully understand how old Dabi is because he is an immortal time lord. He can time travel with ease. Why should his age even matter to begin with?
Who knows what Dabi has witnessed. He may know what was in the Library of Alexandria, or how the Roman Empire fell, or maybe he personally knew Jack the Ripper? What wisdom has Dabi learned from his experience as a time traveler?
This is all the proof I have about Dabi being a time traveler. I don’t know why he hasn’t taken full advantage of this ability. Maybe if he was a better time traveler Twice would be alive, or more people throughout history would know Stain’s agenda.
Thank you for reading this is all a joke and I have wasted my free time.
