Name: Lark Athlai
Age: 19
Birth Date: October 1st, 2003
Gender: Nonbinary (they/them)
Personality: A trickster by trade, Lark likes to play good-natured pranks. Not anything too heinous, just enough to spice up the day. They’re generally friendly with most people, and quick on their feet despite constantly looking like they need a nap… or twenty. Quick to laugh, slow to anger, they’re squeezing every drop out of every day and living life to the fullest.
Powers:
Time Manipulation - Lark can travel forwards and backwards in time to create stable time loops (continuity is important). When traveling to a time they already exist in, they can choose to remain where they are or be pulled to where the current version of themself is. They are unable to travel to any time that’s past the time of their death, although they freely venture into the distant past. The activation of their powers doesn't require much energy, but the actuality of living out more time than any human should be able to leaves them drained if they don't return to the present to recharge.
They can also pause time for a few seconds at a time, though that takes more concentration and willpower. Time doesn't like to be stopped, and will fight to restart if they pause it for too long, leaving them with a terrible headache. One handy side-affect of their powers is that, while displaced from time, they don't age, as their body is put in a sort of stasis until they are back in the present. However, they must continue with the main timeline regardless, as much as they would rather live in the past.
They can sense when time is being manipulated, whether it be their own doing or another traveler. This most often appears in the form of faint music only they can hear, emanating from the source of the disturbance. They also have an always-accurate internal clock, but that's a less impressive power.

Equipment:
Lark, despite being more of a vigilante than a true hero, has their own ‘hero outfit’ - it’s mostly just a reinforced shirt, gloves, sturdy boots, and a skirt. They are fooling absolutely no one, but there isn’t much difference between them in and out of costume, anyways.
Their favored weapon is the shuriken, though they know how to use several kinds of sword and are a decent marksperson. They don't tend to get into any fights they aren't sure they can win. Usually, they travel light, trusting in future versions of themself to supply them with anything they might need.
Fun Facts:
Lark knows when they're going to die and has accepted it as well as they can. Every loop comes to an end. They plan on using the remaining time they have to its fullest, often running several loops within a single day to stretch it out for as long as they can. You can often spot several Larks hanging around the time of a particularly nice moment.
Growing up as an only child, they would often be visited by future versions of themself, keeping them company and keeping them entertained. Because of this, future versions of Lark often keep that same older/younger sibling dynamic with past versions, no matter how small the difference.
