Tear Jerker / Sonic Adventure

  • The death of E-102 "Gamma" at the end of his story in Sonic Adventure. Gamma the bird is free, Gamma the robot however deactivated and exploded in a large fireball. Though what really makes it is the music.
    • In the actual game, one scene between Amy and Gamma becomes a tearjerker in retrospect. Amy expresses hope that she and Gamma will meet again, but that is the last time they ever see each other.
    • The cutscene prior to the battle is particularly chilling, as Gamma assesses the remaining units he must destroy, he looks through flashback images in his memory banks, one of Beta being redesigned... and one of himself. As he looks at his hand and designates himself, we know Gamma's fate is sealed. The lack of background noise aside from a gentle sea wave greatly compliments the somber revelation:
    Gamma: Units remaining...*looks at hand*...Gamma...Beta."
    • Gamma's theme itself becomes hard to listen to after you beat his story, especially that ending synth melody.
    • The prison cutscene. The supposedly intimidating robot confronts Amy for the bird, after she refuses, and in desperation, actually begs him to let it go. Gamma starts feeling pain from his new-found empathy, going berserk before letting them out of their cell and ordering them to escape. He slumps over the door switch, dumbfounded and guilt-ridden at disobeying his master's orders, though Amy shows sympathy and offers him her friendship before leaving. Gamma's heartwrenching theme playing in the background helps none.
      • Amy, despite being locked away and under interrogation, can only feel pity for Gamma over his confusion over why she cares for Birdie so much:
    Amy: *sadly* I feel sorry for you. Eggman failed to give you feelings.
    • After his brethren fail to collect Froggy, Eggman angrily teleports them out of his sight to be made into something useful (which, as Gamma discovers through Beta, isn't a pleasant process at all). Before he vanishes in front of Gamma's eyes, a pained Delta turns to look at him. While no dialogue is said, most sources and media imply that Gamma felt guilty for dooming his brothers.
    • Keep in mind, the E-100 units in Sonic Adventure were essentially siblings. Gamma was forced to kill the only people he ever cared for — with the exception of Amy and his creator Eggman (who he probably saw has his father) — for the greater good of saving the birdies from a Fate Worse Than Death.
    • The worst of it all is how there is no one to mourn Gamma. His cohorts are all dead by his hand, Eggman vanished from the storyline but wouldn't take kindly to hearing that his robot had gone rogue. Sonic, Tails, Knuckles and Big knew him as little more than a generic badnik of Eggman's, and Amy never gets to see him again like she wanted (par the Sonic X adaptation, though that is just as heartbreaking). The only solace is (if Gamma and the bird are separate entities) that the bird family might be thankful to him. If they're intelligent enough.
  • Speaking of Sonic Adventure music, Sadness is truly Exactly What It Says on the Tin.
  • Tikal's implied death.
  • Chaos. Once a peaceful soul who cared for Chao and befriended Tikal, Chaos eventually lost it after witnessing Pachacamac invading and slaughtering the very creatures he tried to protect. Driven over the Despair Event Horizon, he sought vengeance on the very Echidnas that had caused the catastrophe. Then he's sealed inside the Master Emerald to prevent him from harming anybody else, which means he spends 4000 years trapped in a cocoon of anguish and sorrow. Even Sonic sympathises with him.
    Tikal: He must be sealed in the Master Emerald now.
    Sonic: How can that help? It won't change how he feels inside will it? His heart will still remain in turmoil, and his anger just won't vanish! He'll just be trapped forever.
    • To think that Sonic wants to help SAVE the God of Destruction is heart wrenching to think about. All throughout the game, he saw Chaos as this huge enemy, determined to stop him and Eggman from destroying the world. To go from that over the course of the game, to understanding Chaos and wanting to save him could definitely count as a tearjerker.
    • To say nothing of poor Tikal who sealed herself in the Master Emerald with him, just after her entire clan turned on her and the Chao and were destroyed by Chaos. The implication was that in her sorrow she intended to doom herself to that state again to save everyone, and while she given a more peaceful alternative, her original sacrifice still seemingly cost her mortal form.
  • To a certain extent, Knuckles' predicament. He is forced to stay on Angel Island, guarding the Master Emerald. Bound by his duty to his species and to the gem itself, he is always tied to it, unable to stray too far. He will never be free like Sonic and Tails are.
  • In one of Big's recaps, he wonders to himself if Froggy keeps running away because he doesn't like him anymore.
