In Super Robot Wars Reversal, the Big BadDuminuss decides to escape defeat by the heroes through Time Travel via the device built specifically for it after kidnapping the protagonist's Sidekicks. Upon activation, the device explodes, having been earlier sabotaged by one of the sidekicks, because he wasn't going to let Duminuss have its way. Horrified, its homunculi run to their master and do the only thing they can think of to ensure its survival. Realizing it cannot stop the three homunculi from sacrificing their souls to save it, Duminuss offers them a boon: when it destroys the heroes and remakes them, it will be in any way, shape or form they desire. The homunculi accept and promptly sacrifices themselves to regenerate Duminuss' wounds. Despite being nothing more then mindless, soulless husks, their bodies stay by Duminuss, protecting it for the rest of the battle with their lives. This troper almost couldn't beat the game, since it meant killing them and making their sacrifice in vain.
But at least it gives us another set Heartwarming scenes, notably Axel Almer and his Heel-Face Turn event and his eventual speech towards Lamia Loveless, declaring that he finally would consider her a human being (and this is coming from a guy who used to make fun of Artificial Humans).
Later on, Lamia returns the favor when Axel expressed confusion on what to do, telling him to find his paradise. Axel promised to let her be the first to know if he ever finds one. Aww...!
Beforehand, there's also the fact that despite what the homunculi of Duminuss did to them, when Despinis is about to get Killed Off for Real by Dark Brain, Raul and Fiona Gureden speed to her protection, telling her that she doesn't deserve to die and let her join them in the fight against it. Original Generation Gaiden ends with the Gureden siblings adopting Despinis into the family and by the Second Original Generation, she's learned to fix shyness, if only little by little. Aww....
During the Earth Cradle scenario in Original Generation 2, Mai Kobayashi has a combat dialogue towards Ouka Nagisa. It's something like "For Latooni's sake, I'm going to disable your mech!" Never let the love triangle they're in make you assume that the two aren't good friends.
As an extension of this, if certain conditions are met in Original Generation 2, Excellen tweaks the "family" dialogue a bit: she instead wants twin daughters, to which Kyosuke correctly guesses one will be named "Alfimi" and the other "Lemon", after her Alternate Universe counterpart.
At the epilogue of the Second Original Generation, likely as a Call Back to the above, after all their friendship and efforts fighting together, the ATX Team swear to find and resolve Ariel Org'slongevity problem. Excellen chippers in with "Isn't that great, Kyosuke? Ariel can be our daughter!". Kyosuke just smiles at the remark.
