You can't, unless you use some type of hack. I'm warning you: it might corrupt data if you do it wrong.
You cannot steal Pokemon but if you have a gameshark you can put it into your GBA (Gameboy Advance) and enter in a code for stealing the rental Pokemon.
action replay might have something
I've tried to do what it says on u tubebut it didn't workModified by Wyra: There is no legit way to steal a rental Pokemon from the Battle Tent -- "legit" including glitches.

You can't.
no
You have to have an Actionreplay or Gameshark
To steal Pokemon in the Battle Factory you should equip 3 very weak Pokemon first. After getting your rental Pokemon, turn on the magic door cheat for AR or Gameshark. Then you will teleport out of there upon walking through the door and keep the rental Pokemon. BE WARNED because you lose you're Pokemon you had in the party before so only put like 1-3 weak ones there.
