Can you still catch Reshiram/Zekrom in the Dragonspiral if you accidentaly released or traded them?

Lets say for example: you catch Reshiram in N’s Castle (in Black, I’m not talking about Black/White 2) and after you beat the game you go into your PC and release Reshiram, or if you have traded him away, can you still re-catch him in Dragonspiral Tower? Im asking this because #1: Nobody has ever asked this (which I’m kind of suprised at) and #2: one of my friends traded his Reshiram away for a Zekrom, which he found out it was hacked (it was shiny, Reshiram and Zekrom are always shiny locked) so he can’t transfer it to his Y version (the hack will be detected) So can you recatch it, or is your chance gone?

It only matters if you catch it.

Doesn’t matter if you trade it or release it or whatever, once you get that Zekrom/Reshiram in the PokeBall, you will never find it again. When you apply logic, there should only be one in existence in the game as it is a legendary Pokemon. Sorry for your friend.

Hope I helped. :)Sourceand Logic

You can only catch a legendary Pokemon once in a game.

No, there is no way to catch either of them again unless you restart your game.

Recatching Zekrom/ Reshiram only works if you knocked them out and beat the E4 again.
