if the legenaries dont join you team the first time, then yes, you will have to start again.
It seems any legendaries you failed to catch will come back after you beat the Elite Four (if you've already done it, go beat them again).
You can't find Palkia in Pokemon Diamond, but you can in Pokemon Platinum. After you catch Giratina, go back to Spear Pillar, and one of the two legendaries should appear. After you catch the first one, go back again to get the other one.
The 2012 season of Deadliest Catch will start in April 2012!
you win the game! but, you can always go back a fight him again, and do many other things like: complete pokedex catch legendaries train Pokemon
As far as I'm aware, it's impossible to trade Event Legendaries across the globe.
Season 10 (coming June 2011 - final season)
First you have to get the flute. Wake him up to start the battle. Wear him down and then catch him. Save before you try so you can go back again if you don't get him.
In what game? In any game but Mystery Dungeon, YOU CAN'T. Heatran is a legendary, legendaries appear ONLY ONCE. I blew my chance with Uxie. I forgot to save at the start. So the answer - Trade from someone else, Heatran's Gone!
NO... in fact, you can usually catch a good "Going Back To School" sale
probbly i think you can do it any time,i mean i did but you never actually finish or beat the game until you complete the national dex including the LEGENDARIES!!!-zapdoes and the others included!
You need to go back to Sootopolis City where the other legendaries where fighting. He will then break up the fight
Deadliest Catch did come back in 2013. It was also renewed and came back for its 10th season in 2014.
