Summary: Once Erik finally allows himself to decide that Charles is pretty much the best thing since sliced bread, he spends the next week being incredibly bitter that he's Charles' cat and not his boyfriend. ~10,000 [Note: Kitten AU! Written for this 1stclass_kink prompt. Basically, mutant supremacist Erik gets transfigured into a kitten, human Charles takes him in, and Erik really can't help falling in love.]
Charles was an unremarkable professor teaching at the University of Genosha. He wished only for a peaceful life when one night, he caught the eye of Lord Erik 'Magnus' Lensherr, the ruler of Genosha and champion of mutants all over the world. Naturally, everything stopped making sense from there.
At the end of X3, a still depowered Erik travels back in time to meet 1962 Charles. Cue angst, desperate kissing and happy endings for all. Written for the x-men kink meme.
