//It was already decided that Nero was going to be the first one. If we switch, then that would upset him. I'm confident enough that we can defeat that Geodude with just Tackles. On a side note, that could be a great achievement for Nero, whom defeated an enemy which is invulnerable against him.
I will leave open what to do though. It's only fair since I chose the Helix fossil.
If no one has any opinion in some hours, though, I will let Nero stay.
