I didn't mean it that way (Isn't this the second time you misunderstand me already?)
I mean that i opened the box to see if all the eggs where there, and realized that the eggs themselves had nicknames, one of with was "Hippopotas". Because i now knew Hippopotas was in that egg, but not what was in the others, i decided to use Hippoptas as the first.
I mixed up the others when i realized that they maybe where in the order you mentioned the RPG characters (Hippopotas was the last egg in line, fitting that the last on your list was "someone who is defensive")
For the egg's nicknames, i mean that if you not do so, you may be able to see whats inside right when you get them, as the default nickname is whats inside (Seems to be another of pokegen's flaws, as its actually made for making compettitive teams, not eggs )
