By battling your rival or to own it trade one from a freinds game
You can never actually "catch" any starter pokemon. charmander is only available as starter in leafgreen, firered, and the gen I games.
You can't, the only way do get them all together at once is to trade.
First, pick the starter then after you get it, check it picture to see if its shiny or not. If it is, good job. If it wasn't, good luck next time. The chances are very VERY slim to get a shiny starter.
use cheats. and in this case it's HOW to get voltorb as a starter pokemon

You can only get arceus without cheats if you go to an event.
