Good Luck Necklace

Young girl stalks giant robot and wears a piece of jewelery that is connected to his very soul. Creepy.

The Good Luck Necklace is a piece of jewelery Alexis wore during the Unicron Battles portion of the Mini-Con War. She claims that it brings good fortune and was the only thing that could keep them safe while they were trapped inside Unicron. Portent

Alexis fashioned it out of the jeweled stone Starscream brought back for her from Mars, and it was symbolic of her seeming crush/admiration of him. Mysteriously, the stone set within the necklace cracked when Starscream was destroyed by Unicron. Cramp

How Alexis managed to fashion a complex piece of jewelery in deep space is also a mystery.

Santa Claus gives bad/annoying children radioactive rocks for Christmas.

In the dub of this Armada episode, Alexis claims to have made it out of a rock she found on Cybertron, despite its symbolism of her relationship with Starscream, and the fact it looks like it was made out of a piece of the Mars rock he gave her. This is most likely an error, given the other errors in the episode.
