It's a level 100 Magikarp.
Your best bet would be to use the "all Pokemon shiny" code for your game then go fishing in the Resort Area for the level 100 Magikarp that can be caught there. In Platinum, that is.
I think level 100 but why don't you just go catch a gyradoas?
Magikarp evolve at level 20.
Magikarp evolves into Gyarados at level 20.
simply....... no
It is a level 100 Magikarp.
mostly magikarp
level 100 magikarp!?!?
That is a legend. Although, you can catch a Magikarp with an old rod on level 5. Then use a cheat to get numerous rare candies then you can put it on level 100. Or you can just train it to level 100, but that would take forever. Also why would you want a level 100 Magikarp when you could have a level 100 Gyarados. Gyarados is much better and is actually one of the best Pokemon is each game. So my suggestion to you is to have a level 100 Gyarados. I hoped this helped!
There are only Magikarps' in the water at the resort area. If you use a Super Rod, you can hook a Level 100 Magikarp. A level 100 Magikarp can never evolve into a Gyarados because.... its at level 100 unless you use a hack.
You wait to evolve a Magikarp til level 100
dotto the level cap is only up to level 100
