Crossover

The Crossover is a ritual in the IDW portion of the Generation 1 continuity family

The Crossover is a Temptorian religious ceremony marking the transition from this life to the next. It is the ultimate expression of Brand loyalty. It requires participants of three distinct species to be properly performed however. Only two results in a "T'Mup". A Crossover that doesn't quite meet the standards of the participants is known as a "one shot".

Fiction

IDW Generation 1 continuity

After the non-conformist Dire Wraith "CONS4EVA" learned about Temptorian religious customs, he sought to enact the Crossover so he could leave the physical plane behind. To that end, he (somehow) joined the Decepticon social media site, The Big Conversation, and befriended Grumpybox eventually asking him to meet him on Earth so they could enact the Crossover. After recruiting the human MP3, the three misfits enacted the ceremony and succeeded in opening an inter-dimensional portal to a higher plane of existence...a portal much too small for anyone to enter. CONS4EVA took this in stride however and told Crankcase that this may have been the Brand's way of telling them all to make the most out of life. Nonetheless, for their first Crossover, the Scavengers had done a bang-up job. Nothing Will Ever Be the Same Again!
