Some big things were released in this months CoroCoro:
First of all, there are four new pokemon:
1. Gogoat which is a grass type riding pokemon. It is 1.7m and 91.0kg. You can actually ride this Pokémon in the field. It can learn Horn Leech
2. Helioptile which is an electric/normal lizard. It is 0.5m and 6.0kg. It has a new move called Parabola Charge which heals the user while damaging opponents. It uses solar rays to generate electricity.
3. Fletching which is a normal/flying bird and is the Japanese Robin Pokémon. It is 0.3m and 1.7kg. It announces itself with a beautiful voice. It can use the move Flame Charge. Im assuming this is the pidgey/hoothoot/taillow/starly/pidove of Gen 6 but this is just an assumption.
4. Pancham which is a fighting type panda. It is a naughty pokemon and is 0.6m and 8.0kg. It has a new move called Parting Remark which lowers the opponent's attack and special attack and causes the user to switch out.
Pictures of all of them are below.
