Yes it is quite rare
Go to the right of Azalea Town. Heracross are rare in the grass, and you can headbutt the trees.
In Pokemon Crystal Version, a Heracross will occasionally appear when you use headbutt on trees.
Heracross is the Bug horned Pokemon. It can only be found in honey trees but still they are very rare. Sincerely Chicken Lord
yes they are preety rare in crystal they are really rare in gold and silver
NO!
Heracross is in the Safari Zone. Use an Acro Bike to get across the poles (white lines) and go North. The areas there hold Heracross (they are rare and hard to catch so beware).
Yes! It is found at the Safari Zone. Though it is slightly rare!
Heracross does NOT evolve.
You can catch Heracross at around level 30 in pattern bush on one of the sevii islands. I don't think he's too rare.
get rare Pokemon and beat him with them!
wait and the tree will start shaking then there might be a rare Pokemon like combee,heracross or even a munchlax. PS. munchlax is super rare on a tree
Route 14, however, it is rare.
