Thundercats # 47 is a comic book released by Marvel UK and is based on the original cartoon series. It contains the first-part of the story called 'Rampage!'
Synopsis
While out collecting wood to make a table for a banquet the Thundercats were going to host that night, Tygra is bitten by a bug that resembles a tiny scorpion. At the time, he merely assumes he got a splinter from the axe handle and goes on as normal. Later that night, during the feast at the Lair, Tygra looses his mind. He smashes the table, tosses some Berbils around and hurts his own friends. Everyone is baffled, especially when the tiger cannot be reasoned with. Willa explains his behavior means he was likely bitten by the Wood Lucifer bug, which causes inexplicable madness in its' victim. She shockingly recommends Lion-O "put him to the sword" to put him out of his misery, as the cure isn't worth the sacrifice. Of course, Lion-O refuses and inquires about this cure.
Willa tells the tale of her own mother, and how she too was bitten and went mad. The maidens took her, in a cage so she couldn't hurt anyone, to the forest of silence and waited for the quiet to cure her. However, the maidens who stayed with her lost their sanity in the silence. However, Lion-O is willing to risk it to save his friend.
Everyone heads out to look for Tygra, but he returns to the Lair while they're out and attacks the Kittens who were left behind to stand guard - hurting WilyKit badly.
