Odd question, but I'll do my best.
The typical way of getting a Pokemon to level 100 is to train them yourself. I like to just sweep the Elite 4 over and over again until I get there. The Elite 4 eventually level up their own Pokemon (they go from around 40-60 to 50-80) which will make it faster.
Remember, traded Pokemon get an experience boost, meaning they grow a lot more quickly than Pokemon you've captured or hatched yourself.
However, in the Resort Area, using a super rod, you can catch Pokemon up to level 100, though I think they're mainly magicarp.
I suppose you could also use Action Replay, but where's the fun in that? :)
Have the Niational Dex and Super Rod, then go to the Resort Area Use the Super Rod. Eventually you'll catch one.
These magikarp are found in the water in the resort area, use a super rod or surf and use the super rod and it will come up sooner or later, really it's luck.
The strongest Pokemon I met is a 100 lvl Magikarp in Resort Area(I call it King Magikarp :D )

You train your Pokemon to lvl 100 or you can find some at the battle frontier in the place where you rent Pokemon and select open level in Pokemon platinum

Its not a TM. Your Pokemon has to learn it. like Gastly :) (Gengar in lvl 100 with hypnosis is pwnage :p)
You need a member card, wich is obtained via an Pokemon event or hack. PS i have a darkrai lvl 100 obtained that way (at lvl 50)
