People he never met. Before Gohan died, Trunks had no trigger to push himself that far. He hadn't been in countless fights, and failed everyone, or had anyone he cared for nearly die. He hadn't even fought the androids before if I recall.Vegeta, nor Gohan went super saiyan by literally, just training to get more powerful. They got it during training sure. Vegeta's was triggered by giving up hope, and accepting he was going to die. As for the Gohan turning ssj, it literally is him triggering the response to failing all his friends for his whole life, the anger he has at himself when he could have stopped so much or saved so many of his friends.
Goten and Kid Trunks also having super saiyan without any kind of conflict also is terrible even though they trained all the time.
People that these two unstoppable monsters killed that his mentor was fighting for most of his life and wanted to pass on those teachings to. Trunks is failing his planet and mentor by not rising up to the occasion. The fact that he went SS alone is an indicator that he wasn't like "Haha they killed my dad and all your friends but it's not like they'd ever kill my mom" and he was training specifically to beat them for years. He doesn't need a big event when he knows why he's training.
Both filler motivations and both can apply to Trunks anyway.
Vegeta literally got SS because he was training to get stronger and then hated himself for his limitations. Not impossible for a young Trunks to achieve when he can't help his mentor.
And the filler reason again is applicable to Trunks as well. Just because it wasn't shown, that doesn't mean that Trunks didn't want to defend the planet... actually it was shown. He was training for it.
In the manga Gohan didn't even go SS1 on-panel iirc. The anime writing its own fiction doesn't mean that's how things work. Trunks, Vegeta and Gohan all got SS off-panel. Trunks and Goten too. Goku is the only one who got it on-panel. SS2 Gohan is the only other one who reached a transformation on-panel too up until Super. Then it's God. Blue and even Golden Frieza were reached off panel. The U6 Saiyans reached theirs coincidentally enough on-panel.
The only "consistency" is the anime having it triggered by rage on-panel. The Manga is consistent with the Manga. The anime is inconsistent with the anime. Trunks having it for a while makes sense
