In the Webtoon version ESB Luke tanks Vader’s force push without budging.
This then forces Vader to resort to using on TK the metal objects like in the original film version.
The Webtoon version of the OT is stated to be Disney approved but the canon is in a grey area due to some cultural leeway. So essentially these versions have the same canon history, but additional showings via cultural leeway.
The original title also translates directly to Star Wars: Story Before The Force Awakens.
I guess Webtoon ESB Luke is a bit of a powerhouse lol.
