Genus (-virus)

It's about someone who comes to hate the world we live in and decides to cleanse it.

Carefully biding time,

Planning my perfect crime,

Oh, you think I’m shy?

It’s the greatest disguise,

But you won’t expect,

My little project,

All systems checked,

It’s now in effect,

What you really ask?

To destroy this world at last,

I know this place is vast,

Soon it’ll be the past,

You may call me a Tyrant,

I’m strongest with science,

I just released a virus,

Don’t expect survivors
