Cyndaquil / Riolu Fusion Line

Cyndaquil/Riolu -> Quilava/Lucario -> Typhlosion/Mega Lucario

This pokemon evolution line is known for its intelligence and bravery. It can sense the auras of nearby pokemon and humans, but also their heat signatures as well. The last stage is quite aggressive in the wild; use caution when approaching. It tends to challenge anything it sees, and its sought-after, overwhelming strength is no joke.
