Heracross’ Mega Stone (Heracronite) can be found on Route 127. You can pick up the Mega Stone on the route’s southeastern beach area.
Route 127 is directly south of Mossdeep City, so you’ll need to have access to Mossdeep first before you can pick up the Mega Stone.
Heracronite Location (Step-by-Step)
Route 127 is a water route located directly south of Mossdeep City.
On Route 127’s southeast side, you can find a small beach area with a lone Black Belt walking around. In this spot you can pick up Heracross’ Mega Stone lying in a corner on the beach.
For a step-by-step guide of the exact location, start by flying to Route 127.
Step 1: From the Route 127 sign, turn right and get off the island by using HM03 Surf.
Step 2: Start surfing straight down.
Step 3: When you pass by an Ace Trainer, start heading southeast.
Step 4: Go through the narrow opening on the southeast side of this area.
Step 5: Swim straight down until you land on a small beach area.
Step 6: Turn left and walk towards the bottom-left corner. Then interact with the sparkling item in the corner to obtain the Heracronite.
Is Mega Heracross Good?
Mega Stones like the Heracronite are held items that allow certain Pokémon to Mega Evolve, granting them a massive boost to their base stats.
Most Mega Evolutions also change the Pokémon’s ability, which lasts until the battle concludes.
When Heracross Mega Evolves into Mega Heracross, it changes its ability to Skill Link, which makes multi-hit moves always hit five times.
Heracross can learn the following multi-hit moves that could be worth using in its Mega Evolved state:
And here’s another fun fact:
Mega Heracross has the second-highest base Attack in the game, next to Mega Mewtwo X.
It also has impressive defensive stats to go along with its gargantuan Attack stat, making it an excellent wallbreaker.
But Skill Link makes Mega Heracross even more deadly. With reliable moves like Bullet Seed, Pin Missile, and Rock Blast, even Pokémon holding a Focus Sash aren’t safe.
However, it does have a glaring x4 weakness to Flying-types. Mega Evolving also lowers its Speed by 10, making it very easy to outspeed.
