These are the two Pokemon I always have leading my team in Omega Ruby, I never deposit them in the PC except when I try the Masuda Method or Chain Fishing for shinies.
They are Muddy the Swampert and Cloudia the Altaria, they are both level 100 and are...quite powerful....
They can both mega evolve :3
I'll be honest....I have a huge personal attachment to these two, because I worked VERY VERY hard to train them since they were in their pre-evolutions and they helped me a lot throughout the main story, the Elite 4 AND the Delta Episode. ;w;
The best pokemon I ever had in a Pokemon game ;w;
