Throbb

Throbb is a Vampyrum Spectrum bat and is Goth's brother-in-law (in the cartoon series). Throbb is the second villain in Silverwing.

Silverwing
Goth and Throbb were captured by humans and put in the same cell. Goth hated Throbb because he had no royal blood in him and several times he decided to kill him, but decided against it, believing Throbb could be useful in his plan to escape. Eventually the two ripped open an air vent and escaped through it. They attacked several pigeons on their way out and ate them. This caused the owls and pigeons to think the bats the native bats were behind the attack.

When two bats, a Silverwing named Shade and a Brightwing named Marina, were attacked by an owl, Goth and Throbb killed it and told the two that they wanted to help them and wanted the two to lead them to the Silverwing colony. In reality, Goth and Throbb planned to feast on the colony when they found them, lead them to the Vampyrum Spectrum colony so they would become the Spectral bats slaves.

After Marina became suspicious of the Spectral bats, Goth ordered Throbb to kill her. However, Throbb saw another Brightwing and assumed it was Marina, so he killed it. Shade saw him and flew away. Goth and Throbb were shot with darts by humans and the native bats escaped. Goth and Throbb escaped the humans and Throbb told Goth he failed to kill Marina and Shade knew they are cannibals, much to Goth's fury.

Goth and Throbb froze during the winter and starved. Goth wanted to eat Throbb but restrained himself. The two eventually found a group of banded bats that Shade and Marina met earlier and ate them before finally they captured Shade and Marina and Goth almost manipulated Shade to lead them to his olony. Shade pretended to accept and the Spectrals caught a bat. Shade dripped a drug into the bat and when Goth and Throbb ate the bird, they fell asleep. Shade and Marina outwitted the larger bats again.

When they woke up, Goth and Throbb chased after Shade and Marina and caught them at a Thunderhead. Marina's band is ripped off. Goth threatens to rip Shade's wings off unless he tells them where the colony is. However, the elctricity raced through Goth and Throbb's bands and they were electricuted. Throbb was reduced to ashes and Goth was heavily injured, allowing Shade and Marina to escape and find their colony
