Why are the metric and the Levi-Civita tensor the only invariant tensors?

Why don't we consider the "most general" spin 1 Lagrangian, but only a special case?

$(c^{\mu}\partial_{\mu}-m)\phi(x)=0$ not Lorentz-invariant?

Derivative interaction: $\mathcal{H}_\mathrm{int}\neq - \mathcal{L}_\mathrm{int}$. Question about Feynman Rules

How does Weinberg conclude that momentum and angular momentum are unperturbed by interaction terms?

How can a generic potential transform under Lorentz transformations?

Invariance under boosts but not rotations?

Existence proof of Lorentz transformation from lightlike to lightlike vectors

What exactly does it mean for a scalar function to be Lorentz invariant?
