After Cell's absorption of Android 17, Android 16, knowing that he is now well outmatched, attempts to flee with Android 18, but Cell easily intercepts them, thanks to the added speed of Android 17.

In a display of his new power, he takes a direct hit from Android 16 without injury and then easily blasts the Android away, nearly destroying his head effortlessly. Cell turns to Android 18, but she threatens to self-destruct before joining him if he approaches, which will leave him unable to attain his complete form. In an attempt to pacify her, he pretends to be Android 17 by mimicking his voice (a trait probably gained from his absorption) and tells her how wonderful it is to be part of Cell and fulfilling "the great" Dr. Gero's vision. 

REQUIREMENTS - Voice must be very close to the original English American dub.

Here are some examples:
