<p>Eren was still recovering from his previous fight, therefore all of his energy was still going into his regeneration. </p>

Welcome to [anime.se], a Q&A site related to anime & manga! While your answer might be correct, it'd be better if it could be backed up with official sources/references, like from which episode/chapter this is mentioned. You can always [edit] your post to improve it. Meanwhile, consider taking a quick [tour] to understand how this site works.

<p>Well there is an upper limit to how much time and energy you can spend in the transformation. And not to mention his exhaustion from the previous fights.</p>

@AkiTanaka yeah in anime, when Bertholdt and Reiner are running away, I think Reiner mentions that. It is also referenced in the Clash of the Titan arc (the fight on the wall, where Bertholdt has an incomplete transformation due to exhaustion).

<p>In the last episode of season 2, named "Scream", Eren Yeager was unable to transform into a Titan to save Hannes from the Smiling Titan.</p>

<p>Why couldn't he transform?</p>

<p>I don't really read the manga, although I do look at it from time to time.</p>

<p>Has there already been an explanation for this in the manga?</p>
