OC: 'Traveller'

(Humanoid avatar created by Gaia Avatar Maker)

So here's an OC I made whom I plan to give a story to.

Long story short, it's about a cosmic-level being that hops the dimensions, observes what goes on, and tries to make friends with some of the stranger denizens. Among the things it interacts with are living locations, living realms, beings that cause supernovae as their form of language, and other plain weird entities.

Weapons:
"Parts"/"Forms": For each set of observation mediums, "Traveller" displays a different set of extra "parts" that can only be seen when viewed via said medium. Parts are not invulnerable but can only be damaged if one can see/perceive them, and can be regenerated at the cost of the Traveller's health. Parts that get corrupted will be discarded/detached immediately. These are actually part of the being itself. While parts may be invisible to those who do not use the proper medium, "Traveller" can still attack using them, and it can also make its parts visible to all forms of detection if needed.

• To the naked eye, it resembles a chrome spaceship. 
  
• If viewed through glass or transparent substance, "Traveller" has some lights on its surface. These lights can fire out lasers, create holographic projections up to unlimited sizes, as well as solid light projections, again of near-unlimited size.
• If viewed in a mirror, "Traveller" has eldritch-looking tentacles with "eyes" on them claw-like "mouths" at the end of each. These can spawn worm-like tentacle creatures from them, and can be used to attack.
• If viewed via a digital camera, "Traveller" has strange bars and pillars in a huge vicinity around it, all made of energy. These are aligned with its X, Y and Z axes pertaining to its direction, and each bar/pillar is composed of green boxes with a core in them.
• If viewed via magical vision or Ki-based vision, it is covered in metallic-looking plates, which actually serve as armor as well as respawnable dronelike entities. These drones have a variety of abilities
• If viewed via Heat vision, strange "clouds" of unusually high temperature would appear in its vicinity.
• If viewed under Ultraviolet light, it would have a weird glowing aura that can be shaped to attack.
• If viewed via echolocation or sound-based vision, it will initially appear to be in a dodecahedral cage with a metal "plate" at each corner.
• If scryed on, it will be covered in opaque fog.
• Certain advanced forms visible to only specialized methods of observation tend to be even more eldritch and otherworldly. Reported forms include different kinds of entire locations of warped space, a strange presence, beams of light appearing in its vicinity, alien geometrical shapes that should not exist, weapons that can manipulate existence and reality itself, etc.

Abilities and Strengths:
Near-unlimited arsenal: For each method of observation that can be used to view it, it has a different set of Forms/Parts that have their own attacks. As the number of observation methods is nearly limitless, this gives it a near-unlimited arsenal.
Copy Protection: Those who attempt to copy its "parts" ability will be able to do so, and even be able to use them... at a nasty cost. If their "original form" isn't Traveller or its avatars, having those parts will begin to eat away and destroy them down to their very existence within minutes, shortened further per number of "parts" copied. Furthermore, only "parts" that they are "visible" to them can be copied.
Observation Awareness: When "Traveller's" parts are being successfully observed by another being, it will be informed on which beings are observing it, as well as their locations and various statistics.
Invincible main body: The main body of the Traveler is invulnerable to all forms of damage and harmful effects, not even a supernova or black hole can destroy it.
Flight: Using some kind of unknown energy, it can fly at any speed and change direction at will against the laws of inertia.
Space-time Hopping: "Traveller" can immediately teleport to a location in space-time and alternate reality across any multiverse.
Temporal/Spatial Immunity: As a being beyond time and space, "Traveller" is immune to time and space based effects. This allows it to teleport anywhere in the timeline without drastic effects- for example, teleporting from the past to the future would remove all traces of it (and its "parts") in the past, although any actions it has performed may persist.
Omniglot: It is able to understand the "language code" of entities, or the meaning of their words, and easily translate them. Furthermore, it "talks" by sending out "language code" messages that convey meaning, and the recipient will receive a mental, spiritual or electronic message in their most proficient language they understand.
Truesight: As an observer of the multiverse, it has the ability to see through all illusions or cloaking abilities. This also means that it can see its own parts- all of them.
Infinite Memory: As a being that is made to observe and record events, it requires an infinite memory in order to do so.
Immunity to mental/emotional control: Due to having such an alien mind and "coding", it is invulnerable to all forms of mental and emotional control.
Avatar production: "Traveller" is able to produce humanoid (pictured above) and other shaped avatars by detaching a chrome blob from its own body which then shapes itself into a form. Said avatars have similar powers to "Traveller" itself, except weaker, and can communicate with "Traveller" even from an alternate universe.

Weaknesses:
Not Authorized to fight (unless specific conditions are met): As its directive is to observe the universe without interacting in ways that can cause drastic changes, it prefers to not fight at all. The only times it will fight are if it's threatened directly, if a universe or reality is threatened, or if somebody wants to have a training fight in which case it will reduce and adjust its power by using weaker parts. (Yes, that means that if the villain goes after a friend, it cannot fight back, although it will try to save the friend by getting them somewhere else. Either that or talk the villain into directly attacking it)
"Parts" Vulnerability: While its body is invulnerable, its "parts" are not, and it costs the Traveller's (thankfully regenerating) health to regenerate its "parts". Once the Traveller's health is depleted, it will die and be erased from existence itself.
Humanlike Thinking: While his mind is otherworldly, it has a somewhat humanlike way of thinking when it comes to interactions, and as such can make false judgements and assumptions, be naive at times, and clever people can easily manipulate via talking if it does not know their intentions well (compounded by inability to read minds)
Can't directly manipulate emotions/mind: Although certain "parts" can induce madness and sensory overload, it cannot reverse those effects as it is unable to perform any mental or emotional control. If it wants to make friends, it has to get into a conversation- no mental or emotional tricks are available.
Can't create life: One of the few things it cannot create are living objects. Its own avatars are nonliving beings that only share its consciousness.

Weaknesses (Avatar):
Fragile Body: While being powerful and heaving similar, if not weaker weapons that the actual entity itself, its avatars have fragile bodies and can be taken down with ease if damaged enough. They can regenerate if insufficient damage is dealt, however.
Limited Arsenal: The Avatar can only carry lesser/weaker "parts", and their powers are toned down too.

Fighting Style:
When "testing" others, "Traveller" will use one or more sets of "parts" that is appropriate for fighting the opponent. If its parts are destroyed, or if it is heavily damaged in the case of an avatar, it will concede defeat.

If facing a lesser being that tries to attack it unsuccessfully, it will usually not bother unless the being persists. Once this happens, and after a few warnings are given, it will either attempt to incapacitate them or destroy them with weaponry the opponent is unable to perceive.

If facing a being that's a threat to a realm or universe, it BRINGS OUT THE BIG GUNS. These are not limited to creation devices, reality erasers, nullification fields, and even abilities that erase targets from the space-time continuum.

If enough parts are destroyed to put it into critical health, the Traveller will retreat to another dimension to regenerate.

Personality:
"Traveller" tends to be laid back, relaxed, polite, welcoming, and actively attempts to avoid trouble. It tends to "talk" in short, to-the-point sentences, although it can "talk" in longer sentences if the recipient desires so. It may be slightly bored and mischievous at times, playing harmless pranks on others every now and then via its incredible powers.

If threatened, however, what appears to be a defenseless chrome ship will show its assailant a very good reason not to trifle with it.

If he successfully manages to become a trusted friend with someone else, his friend will often receive a great benefit, be it some powerful artifact or powers, especially if said friend is willing to journey with it. Deep down, it feels quite lonely, and one of its hidden desires is a nonromantic partner that can stick with it to the very end.

If disturbances or potential huge disturbances to a universe or reality are found, it will try to get the problem solved via diplomacy or force.

Likes
Interacting with others, making friends, entertainment, new technology or magic, species it hasn't observed.

Dislikes
Huge, unnatural disruptions in the Multiverse, jerks in general.

Extra notes
Would really love a partner that it can travel with for eternity.
