Dabi's awakening is actually from the manga, where after being "knocked out" by Shoto, he awakens and replicates Shoto's "Flashfire Fist: Phosphor" move (hence the "X" shaped fire on his torso) as well as adquiring ice abilities along with his base quirk "cremation"
6:29 I figured it out why Todoroki can use "Ice javelin" His father can use what I call "fire javelin too at Season 2, episode 17, where he attacks the Winged Nomu (Nomu's are deceased body of a person, hiigly modified and also sometimes called "Artificial Humans")
You inserted the wrong moments into the anime, this game did all the same things, if you watched the anime, you would have noticed that all these abilities are very similar in this game
Why in Stain Ultimate Movesets only one final move of him is showcased? The Indomitable Will and also Dabi too only his Final Moveset in Ultimate Prominence Burn is showcased? What about the first three? And also Ice Javelin from Todoroki isn’t shown too
Because it isn't from the anime. Some of Dabi's moves are from the Manga. Stain, Todoroki and Kurogiri have totally made up moves or referenced from somewhere else.
