Open Koffin LL. That's where Reptile is. He's also in lizard form. He's no longer a ninja.

Just in case you need them:

Koffin IV = Frost
Koffin SA = Jax
Koffin XG = Raiden
Koffin KI = Kitana
Koffin UR = Drahmin
Koffin TI = Nitara
Koffin CN = Cyrax
MW = Hsu Hao

Btw, you posted this in the wrong forum. And you posted it twice. Be alot more careful next time. The Classics forum is where you should've posted this.
