In my first proper "i bought this game myself and it isnt my brothers or my mates" game of pokemon, (soul silver if you want to know), i found an Ekans fairly early on. remembering how cool i though Jessie was with her Arbok, I wanted it. Turns out my little ekans was a tank with lots of defense and hp with shed skin and was fucking boss at nearly all the bosses. I called her Nagini. Ever since then i have always tried to have an ekans on my team, getting very frustrated if there wasn't one in my particular game and getting my friend to get one for me.
I know if i was a gym leader, she'd be my signature pokemon.
Bit of a warm up, colour wise
Pokemon belongs to nintendo
