Those are legendary or "exotic" pokemon, so they're kind of "too strong" for the battle tower.
The code for no banned Pokemon at the battle tower in poikemon diamond is: 120F7EF2 00000000 C0000000 00000009 020F7EF4 00000000 DC000000 00000004 D2000000 00000000 I hope this helps.
No, you cannot.
Legendary Pokemon are banned from the Battle Subway.
No way to you hacking noobs
Yes.
Yes. Go to the Union Room and ask the person you link with if they wanna battle ya. Pokemon over level 30 are banned. So go to the colosseum room and choose Single Battle then choose No Resrictions. None of your Pokemon will be banned.
if u mean a party that would be 6 until u battle in the battle tower where they are banned
Legendaries and Eggs are not able to enter into the Battle Frontier. Legendaries can easily defeat the opponents, because of their high stats and powerful moves and Eggs cannot battle.
Lugia and most legendaries have been banned because you are not a real trainer if you walk around with Pokemon like those. The battle frontier is for real trainers, sorry if that sounds like an insult...
They are tagged as being 'Uber' or too powerful for use, I guess.
Because the people there are complete noobs, and they realize that you would win with all legendaries.
I don't think there is one I think the code is only for platinum.
