[Name] Hate Plague [Source] Transformers [Symptoms] 
Bacterial spore of unknown origin transmitted by touch. Induces extreme paranoia and aggression in the infected, causing them to strike out against anyone or anything in an increasingly maddening desire to destroy. Symptoms include a deep reddish glow emanating from the infected. The only curative is intense logic and wisdom, which presumably counters the extreme irrationality the disease causes in its victims. First appearing during the Autobot-Decepticon wars (which necessitated the second resurrection of Optimus Prime), a relatively milder strain is seen again during the events of Beast Machines; Megatron triggers a pre-planted virus in Silverbolt, infecting him and the rest of the Maximals. The strain is cured, again, by intense logic and wisdom.
