I believe everyone has seen the film "venom". I dare say that many friends also want to have such a handsome symbiotic partner. When the venom is running, its own speed can exceed that of a helicopter, while when it is running with four limbs, it is twice the speed of running with two legs.
Venom is a thoughtful symbiont of alien life, which appears almost in liquid form. It needs to be combined with a host to survive, and can give the host powerful superpowers. As long as the venom is attached to a host, it can replicate the host's ability through genes, such as the death attendant's self-healing and spider man's super ability, but the replication ability needs a certain attachment time.
