Probopass. Need 3 psy power in the Chroma Ruins.
To get through that blue energy wall in Pokemon Ranger Shadows of Almia in the Almia castle, capture Froslass as a boss, have 2 Riolu's in the party and use it's power.
Darkrai is the answer because he made Darkness power and when you catch him he will cut all power. Or something like that.
Probopass In the Chroma Ruins Requires Psy Power 3
probopass is in the chroma ruins, its in the cave next to umbreon (you'll need a psy power 3)
You complete every quest(you also must beat the game, which is after darkrai gets caught)
Regigigas, definantly. Whenever he walks, this ring of power comes up and if your styler hits it, 18 damage. I suggest electric type poke assits!
There are alot, these are the ones I know of : Gengar, Gardevoir, Dusclops, Dusknoir and Mismagius!
A lot of pokemon. Ramparados in Peril Cliffs has the highest tackle power of 5. Piloswine in Hia Valley has a Tackle Power of 3, and after the game, you can find a Torterra with a Tackle Power of 4 in disguise at Vien Forest.
Personally, I like Munchlax's power, and flying types are also helpful. Water comes in handy, and grass does zilch for me. It all depends on who youre fighting and how good you are.
Gengar uses psy power 3 , you can find it in Hippowdon temple,Altru building and Altru tower. Gardevoir uses psy power 3 too , but you can only find one in Altru tower. Mismagius knows it too , you can find it in Almia Castle. I hope I helped! :)
