no, i don't think it is the last series and no brock and dawn are not in the new series. They are replaced by Iris and Dent.
Brock was in every series of the except for the recent black and white
croagunk, sudowoodo,happiny (who evolves into chansey).
No he doesn't
no, he is at doctor school
its clay as a gym
Because black and white is a reboot; in the original series ash traveled with brock and misty, 2 gym leaders. So in Black and white series ash travels with cilan and iris, also gym leaders.
Yes they are:) i had to get that from my cousin:)
Because he stayed home to help his dad with the gym
no. its siren, the first gym leader.
He never caught one
Well he may be will return for short time but he want to became pokemon doctor
The next series is called pokemon black and white
