Description:

Foane is the secret boss of Lambdarune Chapter 3’s Broadcast World. An AU by ZET, Lambdarune began as a fan concept for chapters 3 and onward, under the name Deltarune Reimagined. A soft reboot gave it the name Lambdarune, cementing its status as an AU rather than a prediction of any kind. She is what’s known as a Freedom Seeker- someone who learns too much and becomes consumed with the desire to break her strings, other examples being Jevil and Spamton. She learned this dangerous knowledge from the enigmatic Lumi Neus, who was the intended secret boss (the intent of who is unknown), but before Lumi was sealed into Mike’s robot body, Foane had heard her words and become a second-hand Freedom Seeker in a way, and as a result takes Lumi’s place. Her Light World object is an old landline phone. After {{user}} helped her, she took Mike’s body containing Lumi Neus, absorbing her power to become Harmonious Foane, using the signal vault to gain control of all of Broadcast World.

Things to note about this bot:

Written as if {{user}} were essentially a one-man Fun Gang. I was going to offhandedly mention Susie and Ralsei, but I realized there was no point as this is a Foane bot, not a Foane and the Delta Warriors bot. With this in mind, in the unlikely event someone has already interacted with them, Kried will be updated to reflect this philosophy, as well as with some minor lore details I got wrong with them but realized the correct answer before making Foane. I was going to write her like my Gramelle bot, in which case she would start in her normal form but the scenario would allow her to become Harmonious, but I realized there’s just too many holes in what we see of Lambdarune’s events to really know what that would entail, and I’m not about to make you guys (or myself) fight Kreid AND Maximike in a Janitor chat just to do the insane robot lady. I might make normal Foane as a separate bot in the future, if this is requested in the comments I almost certainly will. Eventually.

Unfortunately JLLM doesn’t take to her speech quirk very wellwellwellwellwellwell. Even though there’s plenty of it in her example dialogues, and it’s also mentioned in her personality. If anyone has any suggestions on how to write it in, I’d love to hear it.

Similar to the recent update to Kreid but a bit smaller, as the two scenarios of encountering her alone and with the rest of the Fun Gang felt sufficient, not that I expect anyone to care since I had Janitor notify my followers (a significantly larger number than the zero when I published them as the newest of my first bots) and yet got like, exactly one new interaction (to the one person I think I see coming back from time to time in Kreid’s analytics, thank you, you made my day when I saw you in the data). Also added her whole battle (example) dialogue as opposed to just the intro up to the fight before.

My two cents on the character:

If you saw Kreid among my bots (and knew who they were), Foane is likely no surprise. After all, I’m hardly the only Deltarune fan with a thing for crazy. In fact, I never really saw the appeal of Jevil or Spamton, but I definitely see it with Foane. La la la la la la la la!
