I think I found a way to have...

[thunderhero4]

A pokemon with both a one hit KO move, and a move that guarantees a hit (mind reader and lock on) on pearl or diamond!

ok, so allow me to explain, you will need the following:

~A copy of Red, Blue, or Yellow version
~A copy of Silver, gold, or crystal
~A copy of Ruby, Sapphire, or Emerald
~A copy of Pearl or Diamond
~2 GBAs and a link cable
~A DS or DS Lite

Ok, now heres what you do:

Get to a certain point in yellow, blue, or red to where you get the TM for fissure (I think its for beating Giovanni, if not then you find it)

Teach that TM to the one pokemon that can learn a lock on move AND a 1 hit ko move! (Poliwrath)

Trade Poliwrath to S/G/C using the link cable

Train him until he learns Mind Reader!

Use the system in R/S/E where you can trade pokemon back and forth pokemon from old and new games...

Then use the migrate thing from P/D to get that Poliwrath and you have a pokemon capable of KOing anything in 2 moves!

He's right, I've tried in the past with little success.

I thought there was a "trade from past games" option... :|
