Koopa is not a playable character in Super Smash Bros Melee and you cannot unlock him.
If you are looking for the Koopa trophy, you can get that either through adventure mode or through the trophy machine.
To get Marth you have to beat Classic mode with all the characters, then one last time with Luigi. Then you battle Marth.
And:
To get Roy, Marth's brother/friend, you have to beat Classic mode with Marth without losing any of your lives.
You can't play as Koopa in SSBM and not in any other game

You can unlock him simply by beating Liam Johnston up in fourth grade then beat master hand.BAM! Instantly you unlocked Koopa Kid in super smash bros melee!

Airships in Super Mario Bros. 3 are the Koopa Kid's way of transportation. Although it's design is quite ridiculous, it can fly. It is basically a large boat or ship with several propellers. Defending the Koopa Kids are two strange creatures, the Rocky Wrenches, and Mini Bowser-Bots. Plus, there are cannons and fire engines, which both damage Mario. Once Mario enters the silver pipe at the end of the airship, Mario and a Koopa Kid are locked in battle. Every Koopa Kid's weakness is their head. Jump on their head three times, and the Koopa Kid will hand over the magical wand.
Well Bowser has 7 son's but the most common one is Bowser jr. Others call him"Koopa Bowser Jr.", "Koopa kid", or Baby Bowser, although Baby Bowser is a different character but hes mostly called Bowser jr. Because he looks more like Bowser then Bowser's other kids his other sons are Ludwig Von Koopa, Morton Koopa Jr., Larry Koopa, Iggy Koopa, Lemmy Koopa, and he has one daughter: Wendy O. Koopa
