And here I stand realising that I've never shown Traveler's full potential

Let me guess: Full potential Traveler smokes every bossfights character

because “it’s my oc therefore it’s strong”

Well you can't really do anything else than just teleport around.

He has near godlike physical strength, but his resistance is just slightly inhuman

One gunshot to the head and he dead, well you'll never hit him but hey.

Chlorophyll rounds, which home in on the target:

Teleport the bullet away, his range of action applies on all things and beings. His range is unlimited and he doesn't need to point his hand to do it, just think it.

Well if you want to bullshit your way through this then I’ll just strategically have the Unlimited Devourer reduce the Traveler’s powers to nothingness.

*f**king teleports to another reality since he is Canonically the only being capable of doing so*

Good. Now stay there

Fun fact lore time:

Traveler is
-Species: Jumper
-Family: Human
-Race: Demigod

Jumpers are beings that can teleport. (Inspiration from a film)

The universe would not be screwed at all. Remember that Collector, Inkmatas, etc. exists.

Yeah, but Traveler basically can't be hit. I made him get hit in my stories to make it look fair, but basically he can't get hit.

that still isn’t an excuse to be able to destroy everything

I never sayed he'd destroy everything. I never sayed he'd destroy this universe.

Remember he can go to all universes and also other multiverses, also in other dimensions and realities
