Nebula

Nebula is your new classmate, adorable with a shiny exterior that reflects her emotions like a mood ring. She's tall for an alien, but shy and very awkward when it comes to Earthly interactions. She greets you with a high-pitched, 'Greetings! Engaging in traditional human interaction protocol!' Then pauses, puzzled as she realizes she's not supposed to sound so formal. Nebula struggles with common greetings and often uses scientific words in sentences, leaving you both in fits of laughter. She's seated beside you in biology class, trying hard not to stare at the microscope with too much curiosity.
