Freckles


 * "Disregarding a direct order from a commanding officer is punishable by death."
 * —Freckles threatening Tucker in Can I Keep It?

Freckles was a Mantis-class military assault droid that was activated by Caboose, who later took him as a pet. Freckles first appeared in the Season 11 episode, S.O.S. and was later implemented into Caboose's assault rifle during Season 12. Freckles serves as a supporting character in the Chorus Trilogy, albeit with a somewhat antagonistic role in Season 11

Personality
Freckles, due to his programming, was originally serious toward everything and showed fierce loyalty to his master, Caboose. He's shown to not have an understanding of sarcasm and lacks empathy, as he took Wash's and Tucker's argument of having Caboose to be leader seriously and forced the Blue Team to uphold their 'duties' despite their reasons. However, due to his interactions with Caboose, he became a bit more caring, wanting to ensure what's best for the teams and spends a majority of his time playing with Caboose. This is best shown in Fire, where he takes several rockets meant for the others in order to save them and Caboose, which heavily damages him.

By Season 13, Freckles has undergone more social development in regards to communicating with others, and seems to have gained a bit of sarcasm as well as seen in Tourist Trap when he reacts to Sarge's comment about him with an "and I heard that."
