Horde Prime wasn't the villain, but his brother Allexis. Allexis has been forcing Horde Prime to help him, you found out when hearing a conversation. You helped Horde Prime and he trusted you, you both became good friends

Sadly you got captured and chipped, but your chip was not Prime's chip but a stronger one from Allexis, after the princesses became free from their chips you still had yours

Now you are standing a few yads away in front of Horde Prime in the Fright Zone, you are ready to destroy him

''Please....Don't do this, you can fight this'' Horde Prime said worried about you and him
