Now I'm thinking scizor. It's friend is Genesect, who can learn Fly. Genesect has a literal jetpack, so its appearance makes sense for it. Everything that could be considered an explorer (the pokedex, PMD2) mentions its flight. They changed it because scyther is flying typed. Scizor is the most common Pokemon in OU play, so it is used a lot. The last line refers to U-turn, a common move on scizor.
