Denchura: Starts off as cute bug type but later on becomes a strong powerhouse.
Jiheddo: Hatches from an egg. Haves difficulty with attacking physically until it evolves.
Kurimugan: Caught near the last third of the series with a similar back-story as Tracey's Scyther. Acts as an elder to the trio's Pokémon.
