Do you remember the past chapter where Jiraiya was shocked about Hanzou's death and said: no single man can defeat Hanzou.
We also know Pein has 6 bodies in the secret chamber.
My theory is Pein has used several of his 6 bodies to defeat Hanzou. It was kind of 6vs1 so Jiraiya is still right about the fact Hanzou couldn't loose to a single man.
This chapter confirms that theory largely as I believe Pain has summonned 2 of his 5 remaining bodies. From next chapter it's 3vs1.
I also think each of Pain bodies is specialized in one array of ninja arts:
Ninjutsu, Genjutsu, Taijutsu, Summonings...
Would make sense with the Rinnegan theme of the six ways
Pain only used summoning so far, and the reason is he can't use anything else IMO.
Pain possibly switched to that body to fight Jiraiya so that he could summon more bodies if needed.
