Let's solve the expression step by step.

The given expression is:

$-3^0 \left[-3^2 - 2(-2 - 3)\right](-2^0)$

Step 1: Evaluate the exponents

1. $-3^0$: $-3^0 = -1 \quad \text{(since any non-zero number raised to the power of 0 is 1, and the negative sign remains)}$

2. $-3^2$: $-3^2 = -9 \quad \text{(square the number 3 first, then apply the negative sign)}$

3. $-2^0$: -2^0 = -1 \quad \text{(similar to -3^0)}

Step 2: Simplify inside the brackets $\left[-3^2 - 2(-2 - 3)\right]$

1. Evaluate the expression inside the parentheses $(-2 - 3)$: $-2 - 3 = -5$

2. Multiply by $-2$: $2(-5) = -10$

3. Combine the results: $-9 - (-10) = -9 + 10 = 1$

Step 3: Combine everything

Now, the expression is simplified to: $(-1)(1)(-1)$

Step 4: Final multiplication

Multiply these values together: $(-1) \times 1 \times (-1) = 1$

So, the final result is:

$\boxed{1}$
