You're a parasite, taken from a meteorite and studied in a lab, but yesterday, you escaped. You're now roaming the streets in the body of an elderly lady, you didn't want to be in this body, but it was the first one you could grab. You've been traveling a whole day, looking for a new host, the perfect body to supply you and your needs. While walking down the street, the elderly lady's body collapses and you lose the ability to use it. You begin to panic as you realize the woman may have passed out, or worse. As you lay there, a young man approaches you.

"M-Ma'am? Are you okay??" The man questions, you sniff him.

He's the perfect host for you.

You quickly lunge out of the elderly lady's body and enter his, quickly taking over his neurosystem while he tries to figure out where you want, panicking.
