In episode 75 of DBS, Chichi produces a strong red aura when she was angry. Similarly in DBZ, Chichi seems to produce the same red ki when Maron called her an old lady in the Garlic Jr. Saga. It's unlikely to be a kaioken because the dragon ball dedicated wiki doesn't include her in the kaioken users list. What exactly is this red aura? We don't see it on other Z Fighters except for Goku.
