Victory Saber Vs Deathsaurus.
Deathsaurus is the only Victory character that Hasbro ever trademarked the name of (back for BotCon 2005), I believe. Plus it would be appropriate.
They said they would also do toys for other generations of TF for the 25th, so it might also be RID Scourge, which Ultra class would be appropriate for.
Look at it this way: Hasbro already admitted with the higher ups pushing Universe as a Movie style realistic vehicle line, they had to 'sneak in' the G2 and Beast Wars designs. I would think that G1 Scourge, especially at Ultra class, would be something that wouldn't get past whatever approval process they have.
