Kip. 36: Archeops in the Modern World!

36

Ash and the gang visit a research lab to witness Professor Juniper and Professor Fennel revive an ancient Pokémon called Archen. They begin the revival process using Fennel's Musharna which wakes up Archen. However, it is restless and begins to attack everyone. Meanwhile, Team Rocket decide to steal the Archen, along with the data for constructing a restoration machine. As Archen is sleeping, the professors are pondering what having an Archen in this modern world would be like. As it wakes up, it starts to destroy the lab and its crying causes an ancient plant to start growing in the lab. (Source: Wikipedia)
