Lione is an Autobot Mini-Con in Transformers:Aftermath. He was created, along with Toraizer, by Brainstorm. He is very tenacious, and is designed for fire support. He doesn't have much of a personality, but Brainstorm looks out for him anyway. He is better-armed, but slower than Toraizer.
Lione landed with Toraizer just outside of Salt Lake City, and scanned an ATV as an alternate mode. He then met up with Brainstorm in the city. He was captured by Kira, and reverse-engineered to create the Extermicon Leo.
Lione has very powerful jaws. They are able to snap through a marble pillar with ease. His claws are quite sharp, and he is armed with a solar-beam blaster in his mouth. His alternate mode is capable of travelling at 70 mph on extremely rough terrain. When Powerlinxed to Brainstorm, he grants him the ability to launch solar-beams like his own, only signifigantly more powerful.
Lione is orange with yellow accents, and has red eyes. His robot mode looks like a lion.
