Lieutenant is fiercely loyal to Future Di'angelo, despite him treating the former like dirt. He admits to Di'angelo that it's hard working for his future self, but he does it anyway. This may be most likely because Future Di'angelo won't be merciful on him if he were to disobey him. He usually tries to warn Future Di'angelo of some problem or revolt, to which the latter usually dismisses or doesn't take too seriously, as he thinks he can handle anything with his army or just by himself. Lieutenant usually handles any situation with extreme alarm and panic (which is most likely why Future Di'angelo doesn't pay him much mind, as he handles situations calmly and swiftly), telling to tell Future Di'angelo what he should do or how to handle the problem, and usually gets shot down ("I don't pay you to tell me what to do.").
Lieutenant is a pudgy, short yellowish-tan pug, with light black coloring on his ears and around his mouth, and a long, tightly coiled tail. He wears a pale medium brown shirt and a round beanie-like hat. His eyes seem to be a grayish-brown.
- Lieutenant doesn't seem to have a name other than Lieutenant. Rigbybestie has said that she'll confirm a name for him soon, but it's unknown as of now.
