It's not the mcu version. The mc made it perfect, it now grants all the abilities of all the versions of extremis in comics. If you don't know all the effects look up the wiki page on fandom. It's quite strong.
AstralFear:Oh. Right. This is MCU Extremis. Hmm. Maybe I should reread, to refresh myself.
Just remember author! No matter how long it takes, itâs fine. It is free reading for us, and we love it. Surprisingly many stories are lost not because of loss of motivation, but belief of failed expectations. People can cry, but those same people will be joyous when they notice a chapter even a year later.
