Tear Jerker / Beast Machines

• During "Survivor", Nightscream belittles the rest of The Team for losing the Beast Wars. Rattrap responds with this:
  Rattrap: You watch your mouth, junior! I lost friends in that war!
• Optimus and Cheetor fighting over the possibility of enacting his plan to obliterate all the mechanical life on Cybertron. It was pretty hard watching two of the characters that got along best during the Beast Wars fighting with each other.
• Optimus (and the audience) learning what really happened to Rhinox.
• The real Savage/Noble's death while trying to help Nightscream.
• Rattrap's feelings of uselessness early on, which all come to a head in The Weak Component when he botches up a mission; gets chewed out; and even hears his teammates talking smack about him behind his back.
  Rattrap: Still think you gotta cover for me?! ...You still wanna CUT ME LOOSE?! ...You never believed in me. Ever.
  Optimus Primal: I believed in you.
  • When Optimus calls out the other Maximals for mistreating Rattrap, they all look ashamed and regretful over their actions.
• When Rhinox turns traitor, Rattrap seems to take it to hardest, and trails after him a little bit when he departs. Not wanting him to go.
  • In that same episode, Rhinox's parting comment:
    "Goodbye, Optimus. When we meet again, it will not be as allies."
  • Cheetor takes losing Rhinox pretty hard, too.
    "He wasn't just one of us; he was the best of us."
• Rhinox's spark speaks to Optimus, revealing he has died and rejoined the Matrix. Optimus lets out a loud, mournful scream in response.
• Blackarachnia initially reawakening Silverbolt's mind inside Jetstorm's body and the two are briefly reunited before the Jetstorm personality reasserts itself. There's something undeniably heartwarming about the scene, from Silverbolt referring to her as the "dark poison" of his heart, followed by Blackarachnia affectionately observing "There's only one Transformer who could say something that corny with a straight face..."
• At the end of "Prometheus Unbound", Nightscream is devastated that Savage/Noble, who he bonded with and thought of as a friend, was really Megatron. Rattrap, who suspected something was off about Noble the whole time, comes over to him.
  Nightscream: It can't be...we were friends...
  Rattrap: Um, listen kid...
  Nightscream: Yeah, I know! You told me so but I wouldn't listen!
  Rattrap: I was just gonna say...I'm really, really sorry.
• The death of Optimus Primal.
