Besides that one part where that certain Toa of Ice gave up his life to save the universe, what do you think is the saddest moment is Bionicle? I'm saying it's Lhikan's death. It's just really tragic to see an old hero die in the hands of Teridax.
Gosh, Bionicle is riddled with sadness and hopeless tear-enducing moments. Yes, the death scenes are incredibly sad and all of them get to me, but I think the saddest Bionicle moment would have to be in Legends #2: Dark Destiny--the book not the comic. Jaller's rallied up five of the bravest matoran to go save the Toa Nuva and Takanuva came along with them. As we all know, Takanuva and Jaller have been best friends since forever, and share a strong bond. They love each other as blood-brothers with Jaller even dying for Takanuva when he was still a matoran. Jaller and the five matoran accidentally pass through an invisible wall that keeps matoran in and Toa out. After some heartfelt arguing, Jaller insists that they move on and the toa of light go back to Metru Nui. Takanuva reaches forward to touch Jaller, but the wall stops him. He gets choked up. Jaller tries to lighten the mood by joking and Takanuva says, "...You died once for me...don't die again..." Jaller tries to smile but has to look away from his best friend because he can't control his emotions. T0T!! It's so sad! I can't believe the emotion going through this scene! It ends with Takanuva calling to Jaller and saying, "...You would make a great toa." This seperation--realization that they will never see each other again, to me, is sadder than any death scene.
