The lives of our heroes from "Heroes Reborn" are in danger, thanks to Epic, a weapon developed by Renautas. In the coming episode of the NBC series, we will see how the threat propels all Evos into greatness –or death.

In Episode 5 "The Lion's Den", Tommy (Robbie Kay), the young Evo will learn that he is destined for greatness. In the promo for the episode, we see Tommy asking "Why am I so important" frustrated at being thrust into a fate he is not ready for. However, he will need to buck up and tap into his powers soon, because he is the one "going to help save the world".

The world will need it too, considering the ominous warning Erica (Rya Kihlstedt) gets regarding her weapon at the beginning of the promo. We are talking about a calamity so severe that it wipes out 96% of all species on earth, and the three people who can save our world are Tommy, Miko (Kiki Sukezane) and Malina (Danika Yarosh).

While Miko tried to retrieve her father's sword, she lands herself in trouble. But she and Ren (Toru Uchikado) are persistent in their quest. Meanwhile, we get to see a little bit more of Malina, whose gift seems to be, that of giving life. She is seen growing a full tree and even bringing some butterflies back to life.

Noah (Jack Coleman) and Quentin (Henry Zeborwski) will be seen digging into Renautas, searching for more answers and stop the evil conglomerate from continuing their Evo hunt. They know that Noah's daughter Claire (Hayden Panettiere) is not dead, but is used as a weapon by Renautas, like Molly Walker (Francesca Eastwood), and is now referred to, as "The Shadow".

Carlos (Ryan Guzman) will be seen breaking out of his upgraded El Vengador costume and car to save his nephew Jose (Lucius Hoyos) and Father Mauricio (Carlos Lacamara), who have been captured by Evo hunter Captain Dearing (Dylan Bruce). He will also gain an unlikely new ally in his mission in Episode 5.

Meanwhile, the ex-Evo Hunter Luke (Zachary Levi) will have to face his old demons when he returns home, after his wife Joanne (Judith Shekon) abandons him on learning that he is an Evo.

Watch out for Season 1 Episode 5 of "Heroes Reborn" at 8.00pm (EST) on Thursday, 15 October on NBC. You can also live stream "The Lion's Den" via NBC Live.
