A Cybertronian that was born from one of Professor Princess's experimental "Unicorn Teapots" due to an Allspark shard.
Was born with slightly defective vents, leading to periods of steam releasing, a sensitive olfactory sensor, and the development of a cyber-allergy to anything floral related, even floral-scented teas.
Sandilyn is mute, so he often either communicates through sign language or chirolinguistics (the latter being something that Prowl taught him). When he cries or is frightened, he does seem to have a voice box that lets out sounds alluding to the emotion he is feeling.
While not having a cyber-allergy to Bulkhead's paint, it still causes backfiring. He still likes to watch him paint though and even sometimes requests for specific flowers to be painted.
His frame palette consists of white, heliotrope purple, and pink lavender.
Has a golden horn that splits onto the sides of his neck to release any pent-up steam, a pair of horse-like audials on the top of his helm, a medium-lengthed golden yellow colored tail made from microfibers, and his optics are a light orange.
Has "tea manipulation" like abilities but can't really use them long-term for combat purposes.
Has a section in his processor for "tea recipes" and "tea brewing methods".
Despite not being born with their CNA, Sandilyn has accepted Bulkhead and Prowl as his parents, with seeing Bulkhead as his mother and Prowl as his father.
Sees Jazz as an uncle and Trac-Tor as a grandfather.
Sees Sari as an older sister and Bumblebee as a family friend.
If he and Nanette were in the same AU, he'd only be a couple of inches taller then her.
While he knows that Professor Princess technically created him, he doesn't see her in any positive light.
Only trusts Ratchet with anything medical-related.
Only curls up in Prowl's arms due to actually fearing Bulkhead accidentally crushing him with his.
During the events of Human Error, Sandilyn is terrified that both of his parents are not acting like themselves. He does try to go with Sari to Dinobot Island but she reminds him of his Cyber-Allergy, forcing him to stay until she comes back. He doesn't fight but the sight of their son being frightened of them causes Bulkhead and Prowl to slightly break out of Soundwave's control to avoid harming him.
When Prowl dies, he ends up crying for days on end, only allowing Bulkhead, Bumblebee, Sari, Ratchet, and Jazz to comfort him. He even hates Optimus for a while, blaming him for his father's death. He eventually calms down and apologizes to Optimus, who accepts it, knowing that Sandilyn was grieving the same way Sentinel did.
