I was bored the other night and so decided how hard it'd be to run through Crystal with one Pokémon.
The result? It was actually quite easy. A couple of gyms gave me trouble, like the 1st one; but as I gained levels it got eaiser and eaiser. I did have other pokemon, but only to use the HM moves I didn't want to teach to my Meganium.
About this battle: It went smoother than I thought, I did worry about the Sunny Day + Flamethrower (as such, had to toss in some scapegoats to absorb damage) and I completly forgot about the snorlax, but all in all it was rather simple and shorter than the red battle I did in my LP.
