My idea for a dragon/bug pokemon will always be the same
>early route dungeon is full of the typical weak regional bugs, ie Caterpie, Wurmple, etc
>has an area that you can't access right away
>when you get the HM or equivalent by badge 5 or so you get access to that area
>its the regional pseudo legendary that looks exactly like what you'd expect the weak regional bug to look like
>it evolves in high 20s/early 30s and late 40s for the final form
>the final form is stated to be a protector of the weaker bug mons that can't fend for themselves
Only thing I can't decide on would be for it to be a physical or special attacker
